pH/ORP | About pH/ORP Measurement
About pH Measurement
pH can be defined by the following equation:
Why is pH Important?
pH = -log [H3O+]
pH is the measure of acidity and alkalinity of a liquid. It is one of the most
common parameters measured in a wide variety of industries ranging
from water and wastewater treatment, chemical production, agriculture
research and production, environmental monitoring, chemical and life
sciences research, biochemical and pharmaceutical research, electronics
production to food processing and other industrial applications.
For instance, the level of pH is crucial during the manufacture of sugar.
An inappropriate pH level can result in the formation of unwanted acids
and very little sugar. pH control is also important in sewage treatment
management as it is undesirable to pollute sewers with highly acidic or
alkaline spills.
Here are examples of pH in a few common industrial and household
products:
14
Copper plating [12.8]
In pure water, the H3O+ ion concentration is 1 x 10-7 Moles/litre. Using the
formula definition above, pH value of pure water is derived as follows:
pH value of pure water = -log [1 x 10-7] = 7
There is an equal concentration of H3O+ ions and OH- ions in pure water
at 25 °C. The equilibrium constant, Kw of water, is the product of the H3O+
ion and OH- ion concentrations:
Kw = [H3O+] [OH-]
Hence,
Kw of pure water is = [1 x 10-7] [1 x 10-7] = 1x10-14
Household dye [13.6]
13
Where [H3O+] = The concentration in Moles/litre of the hydronium ion
in solution.
[13.1] Bottle washing
[12.6] Bleach
The Kw of water must remain constant. Therefore, an increase in either
the H3O+ ions or OH- ions will result in a decrease of the other ions,
resulting in acidity (increased H3O+) or alkalinity (increased OH-).

pH is always measured across a medium.
Although the litmus paper is one of the most common methods of pH
measurement, it can only provide a rough indication which might be
insufficient in most applications.
The more accurate method involves the use of a measurement system
that consists of a pH meter and a pH electrode that has a hydrogen ion
sensitive glass bulb. The most common sensing element used in the
electrode is the glass membrane as it is selective for H+ ions i.e. H+ ions
can permeate through the hydrated layer of glass membrane. However
the electrode body may not necessarily be glass.
The movement of ions into the hydrated membrane changes the
electrochemical effect inside the glass which is measured in mV and then
converted via the pH meter to be reflected as a pH value.

[4.3] Orange juice
Hence depending on the concentration of ions in the solution, the mV
and hence pH varies.

The performance of an electrode is dependent on two parameters
– Offset and Slope.

pH Measurement
0
Theoretically, when placed in pH 7.00 buffer at 25 °C, a pH electrode
produces 0 mV which the pH meter reads as 7.00 pH. The difference
between 0 mV and the electrode’s actual reading is called the offset error
which can be as high as ±25 mV.
In other words, when the electrode is not in measurement or in pH 7
buffer solution, the output (or reading) will be known as the offset.
pH Theory
pH is the measure of how acidic or alkaline a substance is on a scale of 0
to 14. pH values below 7 represent the acidic half of the scale; pH values
above 7 represent the alkaline or basic half of the scale. The pH value 7
is neutral, i.e. neither acidic nor alkaline.

While in theory, the mV value should be zero, however in practice this is
rarely the case because of the following reasons:
• Liquid difference
• Bulb composition
• Wire geometry difference and other factors
pH/ORP | About pH/ORP Measurement
In practice, it is unrealistic to achieve zero offset in electrodes.
The Eutech range of advanced micro -processor based
meters provides offset calibration abilities for consistent and
reliable measurements.
the pH value based on the temperature of the solution. Manual
Temperature Compensation requires the user to enter the temperature
of the solution in order to correct pH readings for temperature. ATC is
considered to be more practical for most pH applications.
Slope in pH Electrode
Most Eutech meters offer ATC capabilities. Models with this feature
include the pHTestr™10, 20, 30 and all the EcoScan, CyberScan
handheld and bench pH meters.
As explained earlier the pH electrode produces different mV in
different solution.
More on pH Electrodes
The slope of the electrode is defined as
Slope = mV/pH unit
A perfect pH electrode, at 25 °C, produces a slope of 59.16 mV per pH
unit. For example, for an electrode with 0 mV offset, when placed in
a solution other than pH 7.00, say pH 4.01, it should read mV value of
177.48 mV. Therefore the slope is calculated to be (177.48 mV - 0 mV) /
3 pH = 59.16 mV/pH. The difference between this perfect slope reading
and the electrode’s actual reading is called the slope error.
These theoretical values are not always achieved, even with brand
new electrodes. New pH electrode slope should be between 92 % and
102 % of 59.16 mV. If the slope falls below 92 %, cleaning of the electrode
may be needed.

pH indicating electrodes traditionally use a tip made of pH sensitive
glass. Inside this electrode is a buffer solution with a fixed pH and ionic
strength. A silver wire coated with silver chloride is immersed inside this
internal solution, and establishes electrical contact between the solution
and the meter. The voltage associated with this wire and the voltage
associated with the pH of the internal solution and the inside wall of the
pH sensitive glass tip remain constant. Therefore, changes in voltage from
this electrode result from the voltage developed between the solution
and the outside of the glass tip.
Reference electrodes typically consist of three elements: an internal
reference electrode, a filling solution, and a reference junction through
which the filling solution can “flow”, and provide electrical contact with
the sample and the internal reference electrode. The most convenient
internal reference electrodes are made from a metal (such as silver or
mercury) and its sparingly soluble salt (silver chloride or mercurous
chloride). The filling solution is most often a concentrated solution
of potassium chloride. Most problems with reference electrodes are
associated with the interruption or blockage of flow of the potassium
chloride fill solution through the reference junction.
An Ideal Electrode in Theory has
the Following Properties:
Offset = 0 mV
Slope = 59.16 mV/pH @ 25 °C
0
The electrode system consists of two half cells: a pH indicating electrode,
which is primarily responsive to the acidity (the hydronium ion
concentration) of a solution, and a reference electrode, which provides
a constant voltage and completes the electrical circuit.
pH
The Ideal Electrode
Temperature Compensation
In a perfect pH electrode – one that is zeroed at exactly pH 7 – there
is no temperature effect on the electrode sensitivity at pH 7 no matter
how much the temperature changes. Most pH electrodes are not perfect,
but the errors from changes in temperature are still very minute when
near pH 7, plus or minus one-tenths of a pH, and can be disregarded.
However, the further from pH 7 the solution is and the greater the
temperature changes, the greater the measurement error due to
changes in the electrode’s sensitivity. For most electrodes, the error
will be 0.003 pH/°C/pH away from pH 7.
For example, if a pH meter is calibrated at room temperature (25 °C) and
is measuring a sample around pH 4 at around 5 °C.
Temperature difference: 25 °C - 5 °C = 20 °C
pH away from neutral: 7 pH - 4 pH = 3 pH
Total error: 0.003 x 20 x 3 = 0.18 pH
To overcome this error, pH meters require some form of temperature
compensation to ensure standardized pH values. Meters and controllers
with Automatic Temperature Compensation (ATC) receive a continuous
signal from a temperature sensing element and automatically correct
Single and Double Junction Electrodes
For many applications, a single junction reference electrode is satisfactory.
However, if samples contain proteins, sulfides, heavy metals or any other
material which interacts with silver ions, unwanted side reactions may
occur. These reactions can lead to erroneous reference signals or to
precipitation at the reference junction leading to a short service life.
A double junction reference design affords a barrier of protection to
combat the above interactions. When in doubt about using single
or double junction designs, the safest approach is to use the double
junction as they can be used anywhere a single junction design can
be used. Conversely, single junction designs should not be used where
double junction designs are needed. In most process applications, it is
recommended to use double junction electrodes.
Eutech’s new range of large screen pocket testers pHTestr™ series
feature double junction electrodes that extend useful life and
provide long term cost savings for users.
Normal Aging
As electrodes are used or stored for long periods they will experience
some deterioration in performance. Offsets will change and slope
error will increase. By using the calibration controls these errors can
be corrected. If an electrode is able to be calibrated and is stable and
responsive, it is still a functional electrode and may be used in service
even though it no longer meets “new” electrode specifications. page | 11
pH/ORP | About pH/ORP Measurement
Storage/Shelf Life
pH electrodes have a limited shelf life. Therefore, it is important to have
a backup electrode. It is important to ensure that the spare electrode is
in working condition when required. Electrodes supplied with soaker
storage bottles with special soaker solutions have longer shelf life than
those supplied dry with small caps.
Most Eutech pH electrodes are supplied with storage solutions for
extended electrode life.
A dry or dehydrated electrode membrane will not respond properly to
changes in acidity. The special solution in soaker bottles provides an
environment that maintains pH glass hydration in an acidic environment
and keeps the reference junction wet. If the original solution is no longer
available, the following are acceptable storage media for pH electrodes
in order of preference:
• 4.00 pH Buffer • 7.00 pH Buffer
Other pH buffers or tap water are also acceptable storage media, but
avoid storage in deionised water.
Note: When pH electrodes are stored in deionised water, ions
from pH glass membranes and reference junction solution are
consumed by the deionised water. Deionized water should only
be used for rinsing.
Electrode Maintenance
pH electrodes are susceptible to dirt and contamination and need to be
cleaned regularly depending on the extent and condition of use. Wash
the electrode and reference junction quickly in deionised water. Close
the refilling hole by returning its rubber sleeve or stopper cap (necessary
for only refillable electrodes). Store the electrode as mentioned above,
or as recommended by the manufacturer.
About ORP Measurement
ORP – Oxidation Reduction Potential
Oxidation-Reduction Potential (ORP) or Redox Potential measurements
are used to monitor chemical reactions, to quantify ion activity, or to
determine the oxidizing or reducing properties of a solution. ORP is a
measurement of the electrical potential of a redox reaction and serves
as a yardstick to judge how much oxidation or reduction takes place
under existing conditions.
ORP electrodes measure the voltage across a circuit formed by the
measuring metal half cell and the reference half cell. When the ORP
electrode is placed in the presence of oxidizing or reducing agents,
electrons are constantly transferred back and forth on its measuring
surface, generating a tiny voltage. The ORP measurement can be made
using the millivolt mode of a pH meter.
Major areas of usage include the treatment of industrial wastes, study of
biological systems, oxidation of cyanide, bleaching of pulp, manufacture
of bleach and reduction of chromate wastes.
The measurement of ORP is also useful in pool water treatment as
an indication of sanitation in relation to free chlorine parameter. ORP
technology has gained recognition worldwide and is found to be a
reliable indicator of bacteriological water quality. The table below
illustrates the Kill Time of E.Coli bacteria as a function of ORP value. With
a value of 600 mV, the life of the bacteria is almost 2 minutes; at 650 mV
it reduces to 30 seconds. Above 700 mV the bacteria is killed within a
few seconds. It is therefore necessary for the water to have an ORP value
of at least 700 mV to ensure good water quality. ���

Electrolyte Replacement (For Refillable Electrodes only)
The reference electrolyte needs to be refilled when the electrode has
been used for an extended period, or when the internal electrolyte has
dried up. The old reference electrolyte can be removed with a syringe
and a flexible tube and replaced with a fresh electrolyte as recommended
for the electrode.
���
���
���
���
Electrode Cleaning
Electrodes that are mechanically intact can be restored to normal
performance by the following procedures.
a Salt Deposits
Dissolve the deposit by immersing the electrode in tap water for 10
to 15 minutes. Then rinse with deionised water.
b Oil/Grease Films
Wash electrode pH glass in a little detergent and water. Rinse electrode
tip with deionised water.
c Clogged Reference Junction
Heat a dilute KCl solution to 60 - 80 °C. Place the sensing portion
of the pH electrode into the heated KCl solution for approximately
10 minutes. Allow the electrode to cool while immersed in pH 4.01
buffer solution.
d Protein Deposits
Prepare a 1 % pepsin solution in 0.1M HCl. Allow the electrode to
stand in this solution for five to ten minutes. Rinse the electrode with
deionised water.

ORP value also depends on the pH of pool water. Normal values lie
between 7.2 and 7.6 pH with a tendency to increase to around 8.0 to 9.0
pH depending on the level of contamination. The pH of the pool water
has to be maintained at the optimum level between 7.2 and 7.6 pH by
dosing appropriate chemicals. If the pH of the swimming pool water is
acceptable and the ORP value is below 700 mV, hypochlorite or other
oxidising chemicals should be added.

ORP values in various educational, laboratory and industrial
applications. These include ORPTestr™ 10 pocket tester, handheld
meters CyberScan Series pH 300, pH 310, pH 11 and pH 110, EcoScan

Conductivity/TDS | About Conductivity/TDS Measurement
Introduction to Conductivity, TDS and Salinity
Electrical Conductivity (EC) meters measure the capacity of ions in an
aqueous solution to carry electrical current. As the ranges in aqueous
solutions are usually small, the basic units of measurements are
milliSiemens/cm (mS/cm) and microSiemens/cm (µS/cm).

Conductivity is used widely to determine the level of impurities in water
supplies for domestic consumption as well as industrial use. Industries
that employ this method include the chemical, semi-conductor, power
generation, hospitals, textile, iron and steel, food and beverage, mining,
electroplating, pulp and paper, petroleum and marine industries.
The Principle of Conductivity Measurement
The principle by which instruments measure conductivity is simple – two
plates are placed in the sample, a potential is applied across the plates
(normally a sine wave voltage), and the current is measured. Conductivity
(G), the inverse of Resistivity (R) is determined from the voltage and
current values according to Ohm’s law. G = I/R = I (amps) / E (volts)
Since the charge on ions in solution facilitates the conductance of
electrical current, the conductivity of a solution is proportional to its
ion concentration. In some situations, however, conductivity may
not correlate directly to concentration. The graphs below illustrate
the relationship between conductivity and ion concentration for two
common solutions. Notice that the graph is linear for sodium chloride
solution, but not for highly concentrated sulfuric acid. Ionic interactions
can alter the linear relationship between conductivity and concentration
in some highly concentrated solutions.

About Conductivity Measurement
Specific applications include chemical streams, demineraliser output,
reverse osmosis, stream boilers, condensate return, waste streams,
boiler blowdown, cooling towers, desalinisation, laboratory analysis, fruit
peeling and salinity level detection in oceanography.
The total TDS is a mass estimate and is dependent on the mix of chemical
species as well as the concentration while conductivity is only dependent
on the concentration of chemical species. Some applications require
the measurement of Total Dissolved Solids (TDS) in mg/L, parts per
million (ppm) or parts per thousand (ppt). The TDS concentration can
be obtained by multiplying the conductivity value with a factor which
is empirically determined.
Eutech offers meters that allow the direct reading of TDS values.
These include the TDSTestr™ series, EcoScan TDS 6, CyberScan standard
handheld CON 11, CON 110 and waterproof handheld CON 410. Bench
meters for advanced level laboratory research are the CyberScan
CON 510, CON 1500 and colour touchscreen research-grade CON 6000.
Salinity measurements are common in industries like agriculture,
aquaculture, hydroponics, food, pools and spas where it is necessary to
monitor the salt level constantly. The values are usually read in parts per
thousand (ppt) or % (1 ppt = 1 gram per litre).
The Eutech salinity pocket testers SaltTestr™ series are specially
developed to provide direct readings in these applications.

Conductivity/TDS | About Conductivity/TDS Measurement
Units of Measurement
Conductivity Cells
The basic unit of conductivity is the Siemens (S), formerly called the
mho. Since cell geometry affects conductivity values, standardized
measurements are expressed in specific conductivity units (S/cm) to
compensate for variations in electrode dimensions. Specific conductivity
(C) is simply the product of measured conductivity (G) and the electrode
cell constant (L/A), where L is the length of the column of liquid between
the electrode and A is the area of the electrodes.
Most conductivity meters have a 2-cell electrode available in either dip or
flow-through styles. The electrode surface is usually platinum, titanium,
gold-plated nickel, or graphite. The 4-cell electrode uses a reference
voltage to compensate for any polarization or fouling of the electrode
plates. The reference voltage ensures that measurements indicate actual
conductivity independent of electrode condition, resulting in higher
accuracy for measuring pure water.
The Eutech EC620165 4-cell conductivity electrode (cell constant
K=1.0) with in-built ATC and DIN connector is available for use
with the bench meters CON 1500, PC 6000, PC 6500 and PCD 6500.
ECCONSEN9203J 4-cell conductivity electrode with ATC and 3 m
cable is available for COND 600, COND 610, PCD 650 and CD 650
handheld meters.
Important Features to Consider in a Conductivity Meter
• Auto-Ranging
Meter automatically selects the appropriate range for measurement.
There is no need to change the dial, multiply values on the display, or
turn the potentiometer.
Figure 1
C = G x (L/A)
If the cell constant is 1 cm , the specific conductivity is the same as
the measured conductivity of the solution. Although electrode shapes
vary, an electrode can always be represented by an equivalent
theoretical cell.
-1
Conductivity Temperature Compensation
Conductivity measurements are temperature dependent. The degree to
which temperature affects conductivity varies from solution to solution
and can be calculated using the following formula:
Gt = Gtstd {1 + α(T-Tstd)}
where:
Gt = Conductivity at measured Temperature T in °C;
Gtstd = Conductivity at Reference (Normalisation) Temperature Tstd in °C;
α = Temperature Coefficient of solution at Tstd in °C;
Tstd = Reference or Normalisation Temperature in °C
All meters have either fixed or adjustable automatic temperature
compensation referenced to a standard temperature – usually 25 °C.
Most meters with fixed temperature compensation use α of 2 % per °C
(the approximate α of NaCl solutions at 25 °C). Meters with adjustable
temperature compensation let you to adjust the α to more closely match
the α of your measured solution.
• Temperature Compensation
A cell with built-in temperature sensor allows the meter to make
adjustments to the conductivity or TDS readings based on changes in
solution temperature.
• TDS Conversion Factor
When a solution does not have a similar ionic content to natural water
or salt water, then a TDS conversion factor is needed to automatically
adjust the readings.
• Adjustable Temperature Coefficients
The TDS of certain samples, such as alcohols and pure water, are affected
by changes in temperature. An adjustable temperature coefficient
allows the user to compensate for temperature changes on the solution
being measured.
• Adjustable Cell Constant
Adjusts the reading on the display to reflect use of a cell with a constant
other than k=1.0 cm-1.
Eutech’s wide range of conductivity meters incorporates these
features for consistent, accurate and reliable measurements.
Conductivity Meter Calibration and Cell Maintenance
<< Photo Development
Conductivity meters and cells should be calibrated to a standard solution
before using. When selecting a standard, choose one that has the
approximate conductivity of the solution to be measured.
>> Industrial Boilers
A polarized or fouled electrode must be cleaned to renew the active
surface of the cell. In most situations, hot water with a mild liquid
detergent is an effective cleanser. Acetone easily cleans most organic
matter, and chlorine solutions will remove algae, bacteria or molds. To
prevent cell damage, abrasives or sharp objects should not be used to
clean an electrode. A cotton bud works well for cleaning but care must
be taken not to widen the distance of cell. page | 31

Dissolved Oxygen : :
The measure of the amount of gaseous oxygen dissolved in a solution.

DO | About Dissolved Oxygen Measurement
About Dissolved Oxygen Measurement
DO Electrodes
What is Dissolved Oxygen?
Dissolved Oxygen (DO) is a measure of the amount of dissolved gaseous
oxygen in a solution. Some gases, such as ammonia, carbon dioxide and
hydrogen chloride, react chemically with water to form new compounds.
However, gases such as nitrogen and oxygen merely dissolve in water
without chemically reacting with it, and exist as microscopic bubbles
between water molecules. There are two main ways in which dissolved oxygen occurs naturally
in water: From the surrounding atmosphere, where oxygen in the
surrounding air dissolves readily when mixed into water, up to saturation,
during water movements; Via photosynthesis when oxygen is produced
by aquatic plants and algae as a by-product of photosynthesis. The
amount of oxygen dissolved in water is usually measured in percent
saturation, or expressed as a concentration in milligrams per litre water.
Accurate measurement of dissolved oxygen is essential in processes
where oxygen content affects reaction rates, process efficiency or
environmental conditions, such as biological wastewater treatment, wine
production, bio-reactions, environmental water testing.
Basic Principle in DO Measurement
In theory, the amount of DO in a solution is dependent on three factors,
namely temperature, salinity and atmospheric pressure.
1.Water Temperature
Solubility of oxygen reduces as temperature increases. Hence, the
colder the water, the more dissolved oxygen it contains. Since
temperature affects both the solubility and diffusion rate of oxygen,
temperature compensation is necessary for any standardized
DO measurements.
All Eutech DO meters come with automatic temperature
compensation for accurate readings even in var ying
temperature conditions.
2.Salinity
The amount of dissolved oxygen increases as salinity level decreases.
In other words, freshwater holds more oxygen than saltwater. Since
the presence of dissolved salts limits the amount of oxygen that can
dissolve in water, the relationship between the partial pressure and
concentration of oxygen varies with the salinity of the sample.
Eutech meters feature manual salinity correction to compensate
for variations in ionic concentration. Simply enter the salinity
of the sample in parts per thousand (ppt) to ensure the correct
DO measurements.
3.Atmospheric Pressure
There is a direct proportional relationship between the solubility
of dissolved oxygen and the surrounding atmospheric pressure. As
pressure decreases with increase in altitude, the amount of dissolved
oxygen found in water reduces.
To ensure that your dissolved oxygen is not affected by atmospheric
pressure, Eutech meters come with manual barometric pressure
compensation, with an Atmospheric Pressure Correction Chart
included in the manuals for convenient referencing.
Eutech DO instruments automatically compensate for
temperature, salinity and barometric pressure. The salinity
value and barometric pressure are either measured by the
instrument or entered by the user.

The measurement of DO requires a special DO electrode that is made
up of an anode, a cathode, electrolyte solution and a gas permeable
membrane. The material of the membrane is specially selected to permit
oxygen to pass through. Oxygen is consumed by the cathode which will
create a partial pressure across the membrane. Oxygen then diffuses
into the electrolyte solution. In short, a DO meter actually measures the
pressure caused by movements of oxygen molecules in water or any
other medium. Currently, galvanic and polarographic electrodes are the
predominant methods for measuring dissolved oxygen.
Galvanic Electrodes produce a millivolt output directly proportional to
the oxygen present in the sample. The electrode reaction is instantaneous
and a result is obtained immediately.
G a l v a n i c e l e c t ro d e s a re av a i l a b l e w i t h m o s t Eu t e c h
Instruments DO meters such as the EcoScan DO 6, CyberScan
DO 110 and DO 300.
Polarographic Electrodes require voltage input from the meter to
polarize the electrodes. Since the voltage from an external source may
take up to 15 minutes to stabilize, polarographic probes usually need to
warm up before use to ensure proper polarization of the electrodes.
Polarographic self-stirring DO/BOD probes are available
for use with the Eutech CyberScan research-grade bench
meters DO 6000 and PCD 6500 in US EPA-approved auto
five-day BOD testings.
Biochemical Oxygen Demand (BOD)
The BOD test measures the molecular oxygen utilized in the
biodegradation of organic material and the oxidation of inorganic
material. By measuring the amount of oxygen dissolved in samples at
the beginning and end of a specified incubation period, the relative
oxygen requirements of wastewaters, effluents, and polluted waters
can be determined.
D -D
BODt (mg/L) = 1 2
P
BODt= Oxygen uptake during incubation period t
D1 = DO of diluted sample immediately after preparation (mg/L)
D2 = DO of diluted sample after incubation period t (mg/L)
P
= Decimal volumetric fraction of sample used
BOD is similar to the Chemical Oxygen Demand (COD), which
also measures relative oxygen-depletion. However, the possible
presence of non-biologically oxidisable may render the COD test to
be less accurate.

Turbidity | About Turbidity Measurement
About Turbidity Measurement
What is Turbidity?
Turbidity refers to the concentration of undissolved, suspended particles
present in a liquid measured in Nephelometric Turbidity Units (NTU). It
is important to note that turbidity is a measure of sample clarity and
not colour.
Water with cloudy or opaque appearance will have high turbidity, while
water that is clear or translucent will have low turbidity. High turbidity
value is caused by particles such as silt, clay, microorganisms, and organic
matter. By definition, turbidity is not a direct measure of these particles
but rather a measure of how these particles scatter light.
Why is Turbidity Important?
This determination of clarity in water is important in many manufacturing
operations such as beverage production, food processing and potable
water treatment plants.
For drinking water application, a turbidity value may give an indication
of presence of bacteria, pathogens, or particles that can shelter harmful
organisms from disinfection process. Therefore, turbidity measurement is
particularly useful for water treatment plants to ensure cleanliness.
In industrial processes, turbidity can be part of quality control to verify
the efficiency in treatment or manufacturing process.
Good Measurement Techniques
Turbidity is a very complex analytical measurement which can be affected
by many factors. Some are inherent in the instrument’s design such as
angle of detection, light beam aperture, incident beam wavelength and
colour sensitivity of the photocell.
However, there are other factors such as stray light, air bubbles and
care of vial, which can be prevented through proper care of equipment
and accessories.
The Eutech CyberScan TB 1000 turbidimeter meets the performance
criteria specified by US EPA method 180.1 for NTU measurement.
In addition, the infrared light source models meet the ISO 7027
standards of measurement. The Eutech waterproof handheld
TN 100 turbidimeter designed for testing on-the-go features
laboratory accuracy and excellent repeatability with US EPA
approved non-formazin standards and is ISO 7027 compliant.
vials can be used for measurement provided their readings with the same
solution are matched. That is, the meter gives identical readings or within
the specified repeatability and accuracy of the meter.
Timeliness of Sample
Samples should be measured immediately to prevent changes in
particle characteristics due to temperature and settling. Temperature
can affect particles by changing their behavior or creating new particles
if precipitates form. Dilution water may dissolve particles or change
their characteristics. It is recommended to take samples only when the
turbidimeter is ready to be operated. Samples should not be drawn and
allowed to sit while the instrument warms up.
Other Important Sampling Techniques
1. Samples should not be violently shaken or agitated as particles can be broken apart or air may be entrapped into the fluid. Gentle agitation such as swirling the sample vial is advisable to
reduce particle settling.
2. Sample vials should be used only with the instruments for which
they are intended. Do not mix and match.
3. Perform a visual observation of the sample vial every time a
measurement is made. Ensure that there are no visible bubbles in
the sample and the vial is clean and free of scratches.
4. Samples placed in the turbidimeter should be at the same
temperature as the process flow samples. Changes in temperature
can cause precipitation of soluble compounds and affect readings.
5. Sample vials should be evaluated with a low turbidity water (after cleaning) to determine if vials remain matched. If the
evaluation determines that a vial is corrupted, discard the vial. It is recommended to conduct this evaluation weekly.
6. When in doubt or question about whether a sample vial is too
scratched or stained, throw it away.
The Eutech CyberScan deluxe bench meter TB 1000 allows
instantaneous sampling without having to transfer samples into
vials hence providing hassle-free laboratory research.
Maintain Sample Vials in Good Condition
Sample vials must be meticulously clean and free from significant
scratches. It should be treated on the outside with a thin coat of silicone
oil. This is to mask minor imperfections and scratches that may contribute
to stray light. Sample vials should be handled only by the top to avoid
dirt accumulation (or deposits) and fingerprints that might interfere
with the light path.
Match Sample Vials
Best accuracy and repeatability of turbidity measurement are achieved
using a single, indexed vial. However, for more convenience, different

Colorimetry : :
The measurement of a parameter whose
concentration is proportional to the colour intensity
after addition of known volume of reagent.

Colorimetry | About Colorimetric Measurement
About Colorimetric Measurement
Introduction to Colorimetry
Colorimetry is defined as the measurement of a parameter whose
concentration is proportional (directly or inversely related) to color
intensity after the addition of known volume of reagent(s).
Different chemical substances absorb different and varying visual
light frequencies. Since the absorbance of a substance is proportional
to its concentration i.e., a more concentrated solution gives a higher
absorbance reading, therefore the concentration of a known solute can
be measured using a colorimeter.
Eutech’s latest range of handheld waterproof colorimeters measure
chlorine (free and total), cyanuric acid, pH, chlorine dioxide, bromine
and ozone. The applications include water analysis in swimming
pools, spas, public utilities, industrial wastewater plants, municipal
water, treated water, water conditioning systems and paper and
pulp mills.
The effectiveness of the disinfectants used depends on your system’s
overall water chemistry, and not just on the disinfectants’ concentrations
alone. The following section provides a brief overview on the
measurement of each parameter:
Bromine
Bromine is often used as a disinfectant in indoor or covered water systems.
Due to lower volatility, bromine is more stable in water than chlorine.
Compared to chlorine, the main advantages of bromine are reduced
odour, and skin and eye irritation. In addition, bromine remains effective
at high temperatures and its disinfecting efficiency is not affected by pH
fluctuations. The disadvantages are that bromine is more expensive than
chlorine and it cannot be stabilised for outdoor use.
Eutech’s C 104 colorimeter measures bromine over the range of
0 ppm to 13.5 ppm.
Chlorine
Chlorine and chlorine-release compounds are frequently used as
disinfectants in swimming pools, drinking water and other water
treatment systems. Routine chlorination kills harmful micro-organisms.
The disinfection efficiency is a direct function of the level of free chlorine
in a system. Total chlorine is the sum of combined and free chlorine.
In applications where there is human contact with the water e.g. in
swimming pools and spas, it is essential that the right amount of chlorine
is present. Insufficient chlorine will decrease the disinfectant efficiency;
while excess chlorine will cause skin and eye irritation and become a
health hazard.
Eutech’s C 401, C 301 and C 201 colorimeters measure free and total
chlorine over the range of 0 mg/L to 6 mg/L.
Chlorine Dioxide
The use of chlorine dioxide as a disinfectant is seeing growth in many
industrial applications. Unlike chlorine, chlorine dioxide remains a true
gas dissolved in solution. The lack of any significant reaction of chlorine
p
age | 60
dioxide with water is partly responsible for its retaining its disinfecting
effectiveness over a wide pH range. This property makes it a logical choice
for cooling systems operated in the alkaline pH range, or cooling systems
with poor pH control. Other applications for chlorine dioxide include the
food processing industry; the pulp and paper industries, and the potable
water and waste treatment industries.
Eutech’s C 103 colorimeter measures chlorine dioxide over the
range of 0 ppm to 11.4 ppm.
Ozone
Ozone is one of the strongest and most rapid oxidisers and disinfectants
available. Ozone does not require any stabiliser. It does not corrode nor
cause scaling. In addition, ozone has no smell, does not cause skin nor eye
irritation and does not pose a health hazard. Although more expensive
than traditional disinfectants like chlorine and bromine, because it
does not cause corrosion nor scaling, the long-term maintenance cost
of a water system which uses ozone as a disinfectant may be reduced
compared to using chlorine. Ozone is gaining popularity in top spas and
certain swimming pools.
Eutech’s C 105 colorimeter measures ozone over the range of
0 ppm to 4.1 ppm.
Cyanuric Acid
In applications where chlorine is used for disinfection, cyanuric acid
is often present as a chlorine stabiliser. Low levels of cyanuric acid are
beneficial as they prevent wastage of free chlorine by the sun’s UV rays.
High levels of cyanuric acid cause the chlorine to take a longer time
to kill the micro-organisms. It is important to test your water sample
to determine how much cyanuric acid should be added to maximise
chlorine efficiency.
Eutech’s C 401 and C 102 colorimeters measure cyanuric acid over
the range of 5 ppm to 90 ppm.
pH
The pH value affects the amount of free chlorine that is formed, and
therefore determines the effectiveness of chlorine as a disinfectant. As
pH increases, the disinfecting power of chlorine decreases. High pH
causes scaling of water surfaces, pipework and fittings; this may result in
cloudy water. Low pH can corrode metals in pipework and fittings; this
may cause metal oxides to stain water surfaces.
Eutech’s C 401, C 301 and C 101 colorimeters measure pH over the
range of 5.9 - 8.2.

Introduction to Thermometry
Thermometry is the measurement of temperature or temperature
changes. Temperature measurements are necessary in various industries
ranging from agriculture, HVAC, chemical and manufacturing, food and
beverage, boiler and cooling towers, schools and laboratories to water
and wastewater treatment. There are various types of thermometers that
rely on different principles of measurement.
Probe Sheath Materials
INCONEL® 600 Sheath is ideal for severely corrosive environments
and at elevated temperatures. It resists progressive oxidation.
Maximum operating temperatures are: continuous – 1149 °C,
intermittent –1371 °C.
304 SS Sheath is for general purpose use. It is corrosion-resistant, and is
good for food service and biological applications. Maximum operating
temperatures: continuous – 899 °C, intermittent – 1399 °C.
Eutech offers the user-friendly and feature-packed EcoScan
temperature meters Temp 5, Temp 6 and Temp JKT for routine
indoor and outdoor temperature measurements. The EcoScan
Temp 5 and Temp 6 are paired with the 100K thermistor
temperature probe and 3-wire RTD Pt 100 temperature
probe respectively.
316 SS Sheath has higher corrosion resistance than 304 SS. It withstands
some strong acids. Maximum operating temperatures: continuous –
899 °C, intermittent – 1371 °C.
What is a Thermocouple?
Eutech offers various probes with ungrounded junction and 304
SS sheath. Models include the Type J and Type K probes available
for general purpose immersions in liquids or penetration in meats,
plastic and other semi-soft materials.
Thermocouple probes are composed of two dissimilar metals, joined to
produce a voltage at a given temperature. Thermocouple thermometers
measure, amplify, linearise and display the proportional voltage signal
generated by the thermocouple probe. Thermocouples are used in
most general purpose applications where precision is not a top priority.
They offer a wide temperature range and come in a variety of metal
combinations or calibrations.
SS Sheath with Coating of HDPE with grounded junction is ideal with
corrosive liquids and atmospheres. It has a longer response time and can
measure temperatures to 260 °C.
Exposed Junction has the fastest response time
making it ideal for measuring rapid temperature
changes. Clear coating on most models provides a
humidity barrier for the thermocouple. However, it
is not recommended for use with corrosive fluids or atmospheres.
Ungrounded Junction has a welded junction
insulated from the protective sheath and is
electrically isolated. Longer response time is
expected. Recommended use for conductive
solutions or where isolation of the measuring
circuitry is required.
Grounded Junction has a junction welded to
tip of sheath. Wires are completely sealed from
contaminants. Good response time.
The J, K and T are three of the most common calibrations available.
Although the maximum temperature differs with the diameter of the
wire used in the thermocouple, each calibration consists of a different
temperature range and environment.
Type J and K Probes:
±1 to 4 °C or ±0.4 % probes of reading above 0 °C, whichever is greater
Type T Probes:
±0.5 to 2 °C or 0.4 % of reading above 0 °C, whichever is greater
Thermocouple Selection
Some of the following criteria determine the selection of a suitable
thermocouple:
• Temperature range
• Chemical resistance of the thermocouple or sheath material
• Abrasion and vibration resistance
• Installation requirements (may need to be compatible with existing
equipment; existing holes may determine probe diameter)
The EcoScan Temp JKT is designed for measurement with the Type J,
Type K and Type T thermocouples. The meter is capable of measuring a
wide range of temperatures and is rugged, dust-proof and splash-proof
to IP54 standards, making it suitable for most industrial applications.
Thermocouple Probe Junction Types
Sheaths with small diameters have faster response times. Sheaths
with larger diameters have longer life and are better for measuring
higher temperatures.
What is a Thermistor?
Thermistors are thermally sensitive resistors which change electrical
resistance due to temperature changes. They have predictable
characteristics and offer long term stability. Although response times are
generally faster than other types of probes, thermistors have a limited
temperature range that usually cannot exceed 150 °C.
The Eutech EcoScan Temp 5 has a measurement range of 40.0 to
125.0 ºC using the 100K thermistor temperature probe.
What is RTD?
RTD or Resistance Temperature Detector refers to the measurement of
temperature by measuring the change in electrical resistance across
metal wires. This resistance value is interpreted by an RTD thermometer.
Although the RTD wire can be made of any metal, platinum is preferred
for its excellent repeatability, stability and resistance to corrosion and
chemicals. RTDs are more accurate and stable compared to other probes
such as thermocouples. However they are not recommended for extreme
temperatures. An RTD probe is chosen where accuracy and repeatability
are important.
The Eutech EcoScan Temp 6 is a RTD temperature meter which can
be used with the 3-wire RTD Pt 100 temperature probe for accurate
and reliable measurements.

Electrodes | About pH Electrodes
About pH Electrodes
Magnitude of error = 0.003 pH/°C/pH unit from pH 7
Basic Theory and Application of pH Measurement
Note: The temperature compensation here refers to electrode related
temperature variation and not solution related variations.
pH refers to the power or exponent of hydrogen where ‘p’ stands for
power and ‘H’ is the symbol of the element Hydrogen.
pH is defined as the negative logarithm of the molar concentration of the
active hydrogen ions, pH = -log H+ .
pH provides a convenient way to compare the relative acidity or alkalinity
of a sample at a given temperature. For example, pure water has a neutral
pH of 7, where the activities of hydrogen and hydroxide ions are equal.
If the activity of hydrogen ion is greater than that of hydroxide ion the
sample is described as acidic. In general, as the level of hydrogen ion
activity increases, the pH decreases. A pH below 7 is known as acidic.
On the contrary, as the level of hydrogen ion activity decreases, the pH
increases. A pH above 7 is known as alkaline or basic.
Use of Electrodes for pH Measurement
pH measurement is usually done with the use of a combination electrode.
The combination electrode is an electrode system formed by a glass sensing
half-cell and an internal reference half-cell. As the reference junction acts
as the medium of conductor between the reference electrolyte and the
sample to be measured, it must allow free movement of electrons through
the junction and into the sample. A potential develops on the membrane
surface when a pH electrode comes into contact with a sample and
its value varies with the pH of the sample. This variation in potential is
measured in mV by a meter and is converted to direct pH values.
Slope
The ‘slope’ is the voltage produced per pH. In theory, the value is 59.16 mV
per pH at 25 °C. Practically, the value ranges between 50 and 58 mV.
Selection Criteria
Eutech combination electrodes offer the convenience of having the
reference and measuring electrodes combined in a single housing. They
are offered in a variety of configurations to suit most laboratory and field
application needs.
Electrode Construction
Glass Body
Glass withstands high temperature of
100 °C or more.

Temperature variations can affect pH. However at a certain pH, usually 7,
temperature will not have an effect on the potential of the system. This
is known as the ‘isopotential point’.
If automatic compensation is not practical, the following equation can
be used to determine error:

Prevents interference between the
inner fill solution and sample.
Electrolyte is free of Ag+ ions. Suitable
for use with biological samples. Can be used in place of calomel
reference electrodes.
Electrodes | About pH Electrodes
Internal Reference Types
| Calomel Reference (Hg/Hg2Cl2) |
Calomel reference electrodes can give potentials accurate to within 0.01
millivolt. The repeatability and potential stability of such electrodes are
superior to those of the Ag/AgCl electrode, although only at a constant
and relatively low temperature. Calomel is subject to a constant and
relatively low temperature fluctuation with a temperature limitation of
80 °C. Calomel is recommended for clinical measurement; for samples
containing protein, tris buffers; and for high purity water applications.
Patented Twist-Cap Design
Unlike conventional designs which use rubber sleeves, Eutech’s 620
series refillable electrodes feature a patented refill-hole with twist-cap
design – easy-to-use and leak-proof. Refilling of reference electrolyte is
hassle-free and quick with no wastage.
| Silver/Silver Chloride Reference (Ag/AgCl) |
Ag/AgCl reference electrodes are largely hysteresis-free and can be used
at a higher temperature with lower temperature coefficients. Ag/AgCl
is the best general purpose reference with a wide temperature range
(-5 to 110 °C).
| Double Junction |
A double junction reference is constructed with an Ag/AgCl inner
chamber and a chemically compatible reference solution in the outer
chamber. It is recommended for samples containing organic compounds,
proteins, heavy metals; and other compounds that interact with silver,
such as bromides, iodides, cyanides and sulfides.
Twist-open the cap to
expose the refilling hole
Refillable Vs Sealed Design
Refillable Design
Refill hole allows reference electrolyte
replenishment.
Can be used many times over.
Needs refilling when fill solution is low.
Pour in reference electrolyte
with the refilling bottle (that is
supplied with all electrodes)
Sealed Design
No refill hole. The reference electrolyte
is usually a gel.
Replacement of the electrode is
necessary when it gets contaminated.
Virtually no maintenance is required.
Reference Construction
Twist-close the cap
| Sealed Reference Cell |
Sealed gel-filed reference electrodes are designed for convenience where
minimal maintenance is required. Slightly lower accuracy and shorter life
must be taken into account.
| Refillable Reference Cell |
Selected for high accuracy, stability, and longer electrode life. Refillable
types sacrifice convenience and ease of maintenance.

Electrodes | About pH Electrodes
Types of Reference Junctions
Annular Junction
Fast electrode response.
General Purpose Vs Specialty Applications
Most electrodes come in different stem lengths and diameters for
specific applications.
General Purpose Applications
Usually measures 120 mm (length) by
12 mm (diameter) and can be used for
general applications.
Porous HDPE Junction
Low electrolyte flow, hence more durable.
Flushable Junction
Cleanses by pumping out electrolyte
to remove residue, thus eliminates
clogging problems in viscous samples.
Open Pore Junction
About 200 times larger than ceramic
junctions, ensures increased electrolyte
flow for stable junction potential.
Reference Junctions
Some glass combination electrodes feature an anti-fouling annular
ceramic junction. The annular junction is formulated with a special
ceramic which encircles the glass bulb. Numerous pores in the ceramic
provide lower resistance and more stable pH readings. The plastic body
combination electrodes come standard with a porous HDPE pin junction.
Sleeve junction provides the highest flow rate for difficult samples.
p
age | 84
Specialty Applications
Effective for specific applications. For
instance the spear tip sensor can be
used for the direct pH testing of semisolids and soft materials. Sleeve type
electrode ensures high electrolyte flow
so it is ideal for low ionic strength and
viscous sample measurements. On the
other hand, a flat surface tip electrode
is used for flat samples like paper or
cloth. Micro-stem electrode fits into
thin stem NMR tubes or small vessels.
For harsh use, a durable tough bulb
electrode that is resistant to breakage
is recommended.
Electrodes | About ISE Electrodes
About ISE Electrodes
Introduction to Ion Selective Electrodes (ISE)
The ISE functions in the same principle as the pH electrode. The pH
electrode is the most commonly used ISE that measures the activity of
hydrogen activity in a solution. Ion Selective Electrodes (ISE) respond to
ionic activity or concentration in a liquid because of the characteristics of
the electrode’s sensing membrane. Ideally, the ISE develops an electrical
potential which is proportional to the activity or concentration of the ion
for which the membrane is selective. For example, the fluoride electrode
can be used to directly sense fluoride ion in drinking water.
Eutech offers a wide selection of ISEs for the measurement of
ammonia, bromide, cadmium, calcium, carbon dioxide, carbonate,
chloride, copper, cyanide, fluoride, iodide, lead, nitrate, potassium,
silver, sulfide and sodium.
Gas Sensing – In general, the sensing element of the gas sensing
electrode is made of a Teflon® membrane. The gas permeates through the
membrane and changes the pH of the KCl filling solution. The change in
pH is directly proportional to the concentration of ions present.
Glass Bulb – Glass body ion selective electrodes are constructed similar
to a pH electrode since they have a glass bulb that is sensitive to the
species in question.
ISEs are also available in single and double junction constructions. While
the single junction electrodes are suitable for clean water applications,
the double junction electrodes are designed for harsher applications
such as solutions with heavy metals and organic materials.
Calibrating and Ionic Strength Adjuster solutions (ISA) in 480 ml bottles are available.
Contact your nearest distributor for more information.
Direct Analysis with Ionic Strength Adjustment
In the direct analysis method, a sample concentration is determined by
measuring the electrode potential and comparing to those obtained
in standard solutions. Normally, an Ionic Strength Adjustor (ISA) and/or
pH adjustor must be added to both the samples and the standards. This
helps in that the closer the standard solution matrix is to the sample
matrix, the more valid is the analysis. A number of standard solutions
are used to standardize a pH/mV/ion meter, or to construct a calibration
curve (by plotting the electrode’s output in mV versus the log of the
concentration). The sample concentration is then read from the meter
or the calibration curve.
The advantages of the direct method of analysis are:
1.Many samples (particularly those with relatively simple ionic
backgrounds) can be quickly measured after a single calibration procedure
2.The technique is valid over a wide range of concentrations
3.Sample volume values are not required, and may also vary over a
wide range
Calibrating and Ionic Strength Adjuster solutions (ISA) in 480 ml
bottles are available for the various ions measured. Please refer to
the accompanying instruction sheet of each Eutech ISE.
Other methods of measurement that may need the use of ISA are
the known addition, known subtraction, analyte addition and
analyte subtraction methods that are applicable with the colour
touchscreen research-grade CyberScan series 6000 bench meters.
For specific application methods, please refer to the accompanying
instruction manuals of the bench meters.
Types of ISE Constructions
Eutech carries ISEs with the following three types of
sensing elements.
Membrane/Solid State – The solid, polished crystalline membrane of
the solid state ion selective electrode is prepared from either a single or
mixture of compounds. Measurement of the potential is taken across
this membrane.

Membrane Glass Types
X-1 is especially suited for low temperature, nonaqueous solutions and pH measurements under pH 12.
X-2 is best suited for most pH measurements where minimal or no Na+ is present. It is a low-resistant glass with a very fast and stable response
and is designed for pH ranges of 0 to 13 and temperatures of 0 °C to 135 °C.
X-3 is especially formulated for continuous, long-term use at high temperatures, particularly in strong alkaline solutions above pH 11. It
experiences negligible Na+ ion error above 13 pH. The impedance of the glass is much higher than other glasses, and a slower response will be
experienced at room temperature and below. Response time increases as the temperature is elevated.

GLP Compliance in Field Research
A common problem with fieldresearch is the amount of storage
facilities available for recording data.
Instruments intended to measure
and record should have enough
temporary storage memory for
sufficient samplings to ensure
integrity of the research.
The Principles of GLP (Good Laboratory Practice) represent an
internationally recognised benchmark of test methods and processes
for non-clinical health and environmental safety studies. It provides a
uniform standard upon which researches are carried out and forms the
basis for mutual acceptance of research data between countries. To
researchers and government agencies for environmental control, being
GLP-compliant is important in lending recognition to the integrity of
their research, as well as ensuring a smooth audit process.
This said, managing the quality of a GLP-compliant research without the
support of laboratory facilities can be a tricky affair, especially in settings
where several factors are beyond the researcher’s influence. Since data
collected from field research essentially forms the fundamental to
research work – and that means that results collected from the field
ought to be as accurate as possible – the process of field data acquisition
must be carefully managed, among external elements outside the
control of a researcher, to ensure GLP compliance.
Because of this, in the context of studies involving surface water analysis,
the meters used during fieldwork are not only important in providing
accurate results, but also instrumental in helping to ensure compliance
during data-acquisition. In particular, the OECD’s published Consensus
Document, “Application of the GLP Principles to Field Studies” (OECD,
1999) underscore the need to place special emphasis on two major
aspects of fieldwork – Equipment and Data Recording in the field:
Equipment
The apparatus employed should be of appropriate design and
adequate capacity. For instruments used in outdoors water analysis,
this translates into a need to measure accurately at a required range
and resolution. Housing of the equipment should also be sufficiently
rugged, and waterproof to survive the outdoors elements. At the same
time, sophistication of the apparatus should be balanced with ease-ofuse so as not to hinder the test processes.
To ensure accuracy, all research instruments must be cleaned, checked,
maintained and calibrated periodically, with calibration benchmarked
against national or international standards of measurements.
The GLP Principles require researchers to keep records of each
maintenance and calibration session for auditing purposes. For instance,
the calibration-due alarm in the CyberScan 600 series alerts on a userdefined calibration date allowing them to keep check of calibration
dates easily. Late calibrations are
reflected in the meter, and all
calibration details can be generated
into a report and saved as an ineditable file in the computer using
the supplied Data Acquisition
Software (see Figure 1).
Figure 1:
The CyberScan 600 Series allows the
generation of a detailed calibration
report that records the time, date,
selected buffer option as well as the
electrode performance slope.
Data Recording
The GLP Principles require raw data generated during the field
research to be documented legibly, directly and promptly. Using the
auto-logging function in a meter can facilitate immediate and accurate
data-entry without the risk of accidental data-loss or human error that
may occur with recording on paper. For full traceability, recorded data
must be stamped with time and date of measure.

age | 94
Figure 2: Raw data
collected from the field is
transferred wirelessly to a
computer in the form of a
comprehensive report.
Until the raw data can be transferred
for analysis and archiving, the data
should be secured from accidental
deletion or editing. For this, password
protection and volatile memory
function on the meter is important to
ensure that the acquired data is wellpreserved, even when the equipment
is out of batteries.
Finally, in the case of where data
is transferred to and generated
using a computer programme, the
designed programme used must
ensure identification of the individual
responsible for data-entry. Figure
2 and 3 illustrate how the data
acquisition software accompanying
Figure 3: Programme

identification person responsible for
the entry. The data, which is directly
and wirelessly transferred to the
computer, is presented in the form
of an in-editable report. Researchers
can transfer the information out
onto another programme for further
analysis. Any changes to the raw data
should not obscure the original figures, and should be fully justified for
by means of documentation in the “Note” section.
Unlike the laboratory setting, the nature of fieldwork makes it more
difficult to implement GLP Principles in the research process.
While a field researcher cannot do more to control the weather,
technology has made it possible to obtain better equipment support. By
choosing the right instruments, complying with GLP can be effortless,
even when conducting researches in the field with external factors,
without the infrastructure of a laboratory.

Pool Water Maintenance & Analysis
When it comes to pool management, nothing is more important
than the chemistries of your water. A well-maintained pool with a
good chemical balance keeps the algae away, ensures long lifespan
for your pool equipments and provides for an inviting swim. Here are
some parameters which you should take note of when maintaining
your pool:
When calcium is too high
• Scales formation and clouding of water
5.Disinfection
Chlorine – Chlorine is the most common sanitizer for swimming pools.
Proper disinfection is paramount to preventing water-borne diseases
from spreading between swimmers and prevents the growth of
unwanted algae and bacteria in your pool.
1.pH
Chlorine which has yet to react with other substances in the water is
called Free Chlorine. pH is the measure of how acidic or alkaline your water is. It is the most
important parameter in pool water electrochemistry and affects all the
other parameters in your water.
Chlorine which has already reacted with other substances and is no longer
available to oxidize organic substances is called Combined Chlorine.
When pH is too low (water is too acidic)
• Corrosion of metallic fittings and etching of plaster walls • Stains
from metal rust • Chlorine residuals dissipates quickly • Eye and skin
irritation occur
When pH is too high (water is too alkaline)
• Cloudy water • Scale deposits • Overworked filtration • Reduced
Chlorine efficiency
| Ideal pH Level: 6.8 - 7.8 pH |
Eutech offers a series of waterproof pH testers that measure up to
2-decimal accuracies and allow you to measure temperature at the
same time.
2.Total Alkalinity
While pH is a measurement of the hydrogen ion concentration, alkalinity
measures the ability of a solution to neutralize hydrogen ions. In other
words, it is the measure of water’s resistance to pH change, or how
“sensitive” the pH level of your water is to changes.
When alkalinity is too low
• pH level is extremely sensitive to introduction of chemical or impurities
in the water. This makes it difficult to control and stabilize the pH level
of your water
When alkalinity is too high
• pH level becomes resistance towards change. This makes it difficult to
adjust your pH level
| Ideal Alkalinity Level: 80 -150 ppm |
3.Total Dissolved Solids (TDS)
TDS refers to the amount of dissolved materials in your pool water.
In other words, the lower your TDS level, the better your pool water
quality. TDS is influenced by many factors, among which includes the
chemicals you’ve added to balance the water chemistries. Although a
TDS level of 4,000 ppm has been observed in clean water on occasion,
the recommended TDS level should not exceed 1,500 ppm.
Free Chlorine = Free Chlorine + Combined Chlorine
On the contrary to common beliefs, it is a lack of chlorine which results
in the strong, pungent smell emitted by combined chlorine. Sufficient
chlorine added will dissipate this odor. On the other hand, excessive
amount of chlorine present can cause eyes and skin irritation and pose
as a health hazard.
| Ideal Chlorine Level: (Total) 0.5 - 2.5 ppm ;
(Free) 0.5 - 2.5 ppm ; (Bounded) < 1.0 ppm |
Eutech’s C 401, C 301 and C 201 colorimeters measure free and
total chlorine over a range of 0 - 6 mg/L.
Bromine – Bromine is very similar to chlorine in terms of chemical
structure. However, because of its high boiling point, bromine is less
reactive than chlorine and hence more stable. As a pool disinfectant,
bromine has many advantages over chlorine – it has fewer odors, is
less likely to cause eyes and skin irritation and more importantly, its
efficiency as a sanitizer is unaffected by pH fluctuations. However, the
higher cost of bromine over chlorine makes it a less popular option for
pool owners and operators.
Measure bromine in 3 easy steps with Eutech’s C 104 colorimeter
which provides a range of 0 - 13.5 ppm.
Ozone – Ozone is one of the strongest and most rapid oxidizer available.
It is odorless, does not cause eyes or skin irritation and does not pose as
a health hazard. Although more expensive as a disinfectant, ozone does
not require any stabilizer and causes neither scaling nor corrosion. In
view of this, many top spas and pool owners are beginning to recognize
ozone as a more economical solution to pool sanitizing in the long run
over chlorine.
Eutech’s C 105 colorimeter provides for fast and simple ozone
measurement over a range of 1.4 ppm to 4.1 ppm.
6.Balancing Your Pool Water
The chemical make-up of your water should strike a harmonious balance.
To balance your chemistries, measure and award points to each of the
parameters in table 1.1. Perfectly balanced water should obtain a score of 12.1.
When TDS level is too high
• Low water hygiene level • Staining of pool surfaces • Scaling • Hard water
| Ideal Alkalinity Level: 80 - 150 ppm |
TDS measurement is a simple one-step process with Eutech’s
TDS waterproof pocket testers. User-friendly and so light, it floats
on water!
4.Calcium Hardness & Lime Balance
Calcium hardness refers to the amount of dissolved calcium salt in
your water.
When calcium is too low
• Your pool water may leach calcium from your walls, causing pits to
form in the plaster surface
pH
6.8 = 6.8
6.9 = 6.9

150 = 1.8
200 = 1.9
250 = 2.00
300 = 2.10
350 = 2.15
Pool maintenance can be a breeze in the long run with a proper
maintenance routine in place. The right water treatment will keep your
pool water algae-, bacteria- and pollution-free. More importantly, it
keeps your water safe for a dip with your family.
