Thermo Scientific Alpha pH 2000D

Differential pH/ORP Controller/Transmitter:

pH/ORP:

The Alpha pH 2000D Controller/

Transmitter and combination electrode system employs differential pH measurement technology.

What’s unique about this system is the differential electrode, which uses a pH glass bulb in place of the conventional reference system, making it more resistant to contamination or fouling in harsh wastewater applications. Replaceable salt bridge and reference solution add lifespan to the electrode when junction clogs.

The result: a reliable, long-lasting and cost-saving pH measurement system for demanding environments.

The pH Differential Electrode:

• Cost Savings, Reduced Downtime and Maintenance Costs –

soiled salt bridge and buffer reference solution can easily be replaced at a fraction of the cost of a new combination electrode

• Automatic Temperature Compensation

–

built-in temperature electrode

• Use Any Buffer Standard from 2 to 10 pH as a Reference –

very useful for applications that require adjustable isopotential points

• Built-In Electronic Amplifier

provides a low impedance output from the electrode, and allows analyzers to be located up to 3000 feet away from the electrode

• Ground Rod Minimizes Electrical

Interference

from motors, pumps, transformers and ground currents

• Wide pH range of -2.00 to 16.00 pH at two-decimal accuracy

• ORP mode measures in mV or % concentration, with independent calibration modes

• Control and measure pH and

ORP simultaneously with master-slave operation by placing two controllers side by side

• Wall mount, pipe mount or panel mount options. Compact design of electrode with universal 1.5”

NPT mounting threads enables optimal mounting positions

Easy replacement of salt bridge

Active (process) pH/ORP electrode

Ground rod shields active pH/ORP electrode from electrical noise

Reference electrode

Viton ® reference o-ring offers excellent resistance to aggressive chemicals

Universal 1.5” NPT threads for optimal mounting

Short 6” body with six wrench flats for easy assembly

Smooth surfaces reduce chances of fouling

Larger refillable internal reference chamber minimises effects of dilution and extends electrode life

Replaceable quad junction salt bridge

Better protection of sensing electrode


About Differential pH Measurement:

The Conventional

Combination Electrode:

The conventional combination electrode consists of two parts: the glass electrode and the reference

(Figure 1)

.

The glass electrode contains a silver wire immersed in conductive solution. During measurement, the glass bulb and stem are the only parts which come in contact with the sample. Hence, contamination of the silver wire and conductive solution does not occur.

The reference electrode, on the other hand, is constructed simply with a porous junction and a silver wire. This porous junction allows the reference electrolyte to flow from its chamber to the sample, establishing a connection between the two. However, the porosity also allows contaminants to flow into the reference chamber, reacting with the electrolyte and/or silver wire.

The reference electrode is also susceptible to clogs. In the case of conventional combination electrodes, the entire electrode must be replaced due to a clogged reference electrode.

When contamination and clogging occurs, performance of the entire electrode is compromised.

The Differential Electrode:

The differential electrode replaces the exposed silver wire with a design built on the benefits of a pH glass electrode

(Figure 2)

.

Quadraple junction salt bridges and an electrolyte-filled chamber act as barriers to prevent contaminants from entering the inner chamber, while at the same time, allowing connection between the reference electrolyte and the sample.

In the event of clogs, the salt bridges and electrolyte are easily replaceable, reducing downtime and cost of maintenance.

An individual liquid ground is also built into the electrode, effectively eliminating noises from ground loops potential

(Figure 3)

:

(E1 – E3) – (E2 – E3) = E1 – E3

With these design improvements, the differential electrodes enjoy a longer lifespan in harsh wastewater environments as compared to conventional electrodes.

Measurement of pH in wastewater poses several challenges, one of which is fouling of the reference electrode system

Electrode

Asymmetrical mode works well in environments with where there is little or no electrical noise. When there is electrical noise, the noise acts as a common signal and is picked up by both the pH and the reference electrodes. However, since the reference electrode is grounded to the ground potential of the amplifier, electrical noise will be present only on the pH electrode.

This noise is amplified along with the pH signal, which causes reading fluctuations in an electrically noisy atmosphere. Electrical noise from a DC source (as in an electroplating tank) will typically result in stable but incorrect values.

Symmetrical mode avoids grounding the reference electrode by reconfiguring the input to a floating differential mode. The electrical noise appears equally on the pH and reference electrodes, and is therefore rejected by the operational amplifier.

The Alpha pH 2000 transmitter offers an option for Symmetrical Mode of Operation. To take advantage of

Symmetrical operation, you must have an electrode with a solution ground (potential matching) pin.

If your electrode does not have a solution ground, be sure to set the controller to Asymmetrical mode.

Thermo Scientific Alpha DO 2000

Dissolved Oxygen Controller/Transmitter:

Dissolved Oxygen:

With a wide measuring range of 0 to 20 ppm or 0 to 200 % saturation, Alpha DO 2000 controller/ transmitter is ideal for use in a variety of applications, ranging from water treatment and monitoring to pharmaceutical and food processing.

Meter comes in both Galvanic and

Amperometric versions.

• Readings values in mg/L or % air saturations, selectable from menu options

• Quick, easy calibration using atmospheric air as calibration media for 100 % air saturation

• Pressure, Salinity and Automatic

Temperature Compensation

The Galvanic Electrode

(ECDOGEN-S & ECDOTPII-S)

The Amperometric Electrode

(EC237150 & EC237450)

Rugged and long-lasting, the galvanic electrode requires no warm-up time and prevents zero drift by recreating H 2 O within the electrode. This prevents change of pH to the electrode and allows it to recycle within the probe. The result: galvanic sensors have long lifespans and require low maintenance costs.

The amperometric dissolved oxygen electrode contains special membranes that are designed to require almost zero maintenance. These unique membranes stay stable even under harsh ambient conditions and high pressure. This enables the sensors to capture accurate

DO readings within short response time at required flow as low as 0.02 m/s.

Sensor Installation Tips

There are two main sensor installation configurations:

1. In-line Installation where electrodes are installed into the piping system

• In-line installation is best in a location which is always flooded.

It is recommended that the electrode be installed in the dead leg of a pipe tee fitting

(Figure 4)

This reduces the velocity of the

. fluid as it flows into and around the electrode before flowing upwards and away

• Take into consideration the amount of cleaning and calibrating your application imposes on the electrode. In-line mounting may mean the process has to be shut down, or that a portion of the pipe must be drained in order to remove the electrode

• Remove cables before unscrewing electrodes from the pipes to avoid twisting and damaging wires or shielding

2. Submersible Installation where electrodes are submerged in tanks

• Use a baffle in submersible installation to avoid air bubbles from being trapped inside or around the electrode, distorting readings

(Figure 5)

. Install your electrode away from mixers, sparges and inlets

• Mount electrodes near outlets of the tank, away from points where reagents are introduced.

This allows time for reagents to mix thoroughly and react with your effluent water. Some applications, such as neutralization processes that require pH control, are best executed with submersible configuration than with in-line configuration, where both pH and flow are variables

• Some sensors must be mounted at a ±30 ° angle

(Figure 6)

. This ensures that the electrolyte remains in contact with sensing tips, and prevents bubble entrapment within the electrode membrane. Some electrodes, however, like our DO Sensor,

EC237450, can be installed even upside-down – very useful for measurements in tanks that are nearly empty

• Keep connection between electrode and preamplifier dry and clean at all times. Moisture in this area may cause permanent damage

Whether you’re considering an in-line or submersible configuration, the principle considerations are to avoid air bubble entrapment, as well as to ensure maximum exposure of the sensor to your process water.

In processes when temperature and pressure of the process liquid exceeds the sensor ratings, a sidestream system may be used, where a portion of the process liquid is constantly directed to the sensor.

Applications

pH Application

The pH neutralization system is crucial in the back-end process of treating effluent water in industries such as pharmaceutical, F&B manufacturing, electroplating and seawater desalination etc.

In a neutralization system, effluent water flows into a tank where a pH electrode picks up the pH level of the process water. When this pH level goes below or above set limits, the electrode sends a signal to the meter, which in turn, adjusts the pH level in the tank by operating two chemical pumps that release acid or alkali into the tank as needed.

pH & ORP Application

In applications where pH and ORP must be measured and controlled simultaneously, two Alpha pH/ORP 2000 meters can be placed side by side where the pH meter acts as the primary controller – the ORP controller will only operate its pumps when pH is within set limits.

Conductivity Application

In the back-end process of the electroplating industry, conductivity monitoring systems monitor the conductivity of rinse water in metal finishing facilities, maintaining chemical concentrations at levels that provide adequate rinsing and at the same time, prevent excessive dragin to subsequent process tanks. When rinse water conductivity exceeds set limits, the meter activates a valve that introduces more water into the rinse tank, reducing conductivity of the rinse water.

pH & DO Application

In biological wastewater treatment, both dissolved oxygen level and pH level are vital in ensuring efficient breakdown of biological waste in the effluent water.

A dissolved oxygen sensor picks up the temperature and

DO level of the process water in the biological wastewater tank. It then relates this information to the DO meter, which controls an air pump to increase or reduce the amount of oxygen level that goes into the effluent water.
