OPERATIONAL GUIDE
INITIAL PREPARATION
The instrument is supplied complete with rechargeable batteries. Proceed with
a complete charging process before starting (see page 58).
To prepare the instrument for field measurements close the serial communication socket and all unused connector sockets with proper stopper (to ensure
waterproof protection) (HI 98183/4/5 only). Use the holed temperature
rubber cork for the temperature socket when temperature probe is connected
(HI 98183/4/5 only).
Connect the pH electrode and the temperature probe to the BNC and temperature sockets on the top of the instrument. Push the pH electrode sleeve to cover
the connector accomodation. The temperature probe is used in conjunction
with the pH electrode to utilize the instrument's ATC capability, but it can also
be used independently to take temperature measurements. If the probe is
disconnected, temperature can be set manually with the ARROW keys (see
page 13 for details).
Turn the instrument ON by pressing ON/OFF key.
At start-up the display will show the Hanna logo for a few seconds followed by
the percentage indication of the remaining battery charge, then enters the
measurement mode.
After measurement switch the instrument off, clean the electrode and store it with
a few drops of HI 70300 storage solution in the protection cap (see page 62).
The auto-off feature turns the instrument off after a set period (default 30 min)
with no button pressed to save battery life. To set another period or to disable
this feature, see SETUP menu on page 33.
The auto-off backlight feature turns the backlight off after a set period (default
1 min) with no buttons pressed. To set another period or to disable this
feature, see SETUP menu on page 33.
pH MEASUREMENTS
To take a pH measurement remove the electrode protective cap and simply
submerge the tip of the electrode (4cm/1½”) and the
temperature probe into the sample to be tested.
If necessary, press RANGE until the display changes to
the pH mode. Use Mode key to select the pH resolution.
12
Allow for the electrode to adjust and reading to stabilize (hourglass symbol
turns off).
On the pH screen are displayed:
• pH reading with the selected resolution.
• Temperature reading in the selected unit (ºC or ºF).
• Temperature compensation mode (MTC - manual, ATC - automatic).
While in MTC mode the indicate that the temperature can be
manually changed using ARROW keys.
• Electrode condition during the calibration day.
• The buffers used in last pH calibration (if feature is enabled in SETUP).
• Battery level indicator.
• Available functional keys in according with the model.
In order to take more accurate pH measurements, make sure that the
instrument is calibrated (see page 16 for details).
It is recommended that the electrode is always kept wet and rinsed thoroughly
with the sample to be measured before use.
The pH reading is directly affected by temperature. For accurate pH measurements, temperature must be taken into consideration. If the sample temperature is different from the temperature at which the pH electrode was kept, allow
a few minutes to reach thermal equilibrium.
To use the instrument's Automatic Temperature Compensation feature, submerge
the temperature probe into the sample as close to the electrode as possible and
wait for a few seconds.
If manual temperature compensation (MTC) is desired, the temperature
probe must be disconnected from the instrument.
The display will show the default temperature of 25 ºC, the last measured
temperature reading, or the last set temperature, with the “MTC” indication.
The “MTC” indication and the symbol light up on the LCD to indicate that
the instrument is in MTC mode and the ARROW keys can be used to enter the
desired temperature value.
Note: When in MTC the user can press and hold the ARROW keys, and the
instrument will start incrementing /decrementing the temperature value.
The instrument keeps measuring and the display is updated periodically.
13
ORP MEASUREMENTS (not for HI 98180)
To perform ORP measurements, connect an optional ORP electrode (see “Accessories“
section) to the instrument and turn it ON.
If necessary, enter the mV mode by pressing RANGE
until the display changes to mV.
Submerge the ORP electrode tip (4cm/1½”) into the
sample to be tested and wait a few seconds for the
reading to stabilize.
Measurements are displayed with 0.1 mV resolution.
The “ATC” (or “MTC”) message is turned off because mV readings are not
temperature compensated.
For accurate ORP measurements, the surface of the electrode must be clean
and smooth. Pretreatment solutions are available to condition the electrode
and improve its response time (see “Accessories” section, page 65).
RELATIVE mV MEASUREMENTS (not for HI 98180)
To enter Relative mV mode, press “MODE” while in mV measurement mode. The
relative mV reading will be displayed along with the Absolute mV value and
the current temperature readings.
The relative mV reading is equal to the difference between the absolute mV input
value and relative mV offset established in the relative mV calibration.
Note: If using the pH electrode while in mV mode, the instrument will
measure the mV generated by the pH electrode.
ISE MEASUREMENTS (HI 98184, HI 98185 only)
To perform ion concentration measurements, connect an optional ISE electrode
and the corresponding reference (if necessary) to the instrument and turn it
ON.
14
Enter the ISE mode by pressing RANGE until the display changes to ISE
range.
Submerge the ISE electrode tip (4cm/1½”) into the sample
to be tested and wait a few seconds for the reading to
stabilize.
The ISE reading will be displayed along with the current
temperature reading.
The “ATC” (or “MTC”) message is turned off because ppm readings are not
temperature compensated.
In order to take accurate ISE measurements, make sure that the appropriate ISE
electrode type and ISE unit were set in SETUP menu (HI 98185 only), or the
proper ion charge is set (HI 98184 only), and the instrument was calibrated
(see ISE CALIBRATION for details, page 27).
Notes: • When the reading is out of range, the display will flash the closest
full-scale value.
• The instrument will display “----” on the primary LCD if it is not
calibrated. Perform at least a one-point calibration in order to
take ISE measurements.
• Changing the ISE electrode or the ion charge will need ISE range
calibration.
TEMPERATURE MEASUREMENTS
Connect the HI 7662 temperature probe (HI 98180/1/2) or the temperature
connector (HI 98183/4/5) to the appropriate socket. Immerse the temperature
probe (HI 98180/1/2) or pH electrode (HI 98183/4/5) into the sample and
allow the reading on the secondary LCD to stabilize.
Note: The temperature can be displayed in Celsius degrees (ºC) or in Fahrenheit
degrees (ºF) (see SETUP for details, page 33) (not for HI 98180).
BACKLIGHT FEATURE
The instrument is provided with a Backlight feature, which can be easily
toggled on and off through the keyboard by pressing LIGHT.
Note: The backlight automatically shuts off after a set period (see SETUP
for details, page 33) with no buttons pressed.
15
p H CALIBRATION
It is recommended to calibrate the instrument frequently, especially if high
accuracy is required.
The pH range should be recalibrated:
• Whenever the pH electrode is replaced.
• At least once a week.
• After testing aggressive chemicals.
• When calibration alarm time out is expired - “CAL DUE” blinks (if feature
is enabled in SETUP).
• If “Outside Cal Range” message blinks during pH measurement (the
measurement range is not covered by current calibration, if feature is
enabled in SETUP).
PROCEDURE
All the familly instruments offers a choice of 7 memorized buffers (1.68, 4.01,
6.86, 7.01, 9.18, 10.01 and 12.45 pH). HI 98182/3/4/5 allow the user to set
up to 5 custom buffers. The set custom buffers are the buffer values at 25 ºC.
When a custom buffer is selected during calibration, the “Custom” functional
key is displayed on the LCD. Press Custom key in order to enter custom buffer
changing mode. Use ARROW keys to change the value in a ±1.00 pH
window, in according with the temperature reading and then Accept. Press
ESC to leave custom buffers value unchanged.
For accurate pH measurements, it is recommended to perform a calibration in
maximum allowed points. However, at least a two-point calibration is suggested.
The instrument will automatically skip the buffers used during calibration and
the buffers which are in a ±0.2 pH window, around one of the calibrated buffers.
• Pour small quantities of selected buffer solutions into clean beakers. For
accurate calibration use two beakers for each buffer solution, the first one for
rinsing the electrode and the second one for calibration.
• Remove the protective cap and rinse the electrode with some of the buffer
solution to be used for the first calibration point.

is broken or clean it following the Cleaning Procedure (see page 65). Check the
quality of the buffer. If necessary, change the buffer.
Wrong slope
The calibration cannot be confirmed.
The evaluated slope is less than the lowest accepted value (80% of default
slope).
The evaluated slope is more than the highest accepted value (110 % of default
slope).
21
Wrong old slope
An inconsistency between new and previous (old) calibration is detected. Clear
old calibration parameters and proceed calibration from the current point. The
instrument will keep all confirmed values during current calibration.
Note: For one-point calibration the electrode condition is not displayed in the
measurement screen.
Each time a buffer is confirmed, the new calibration parameters replace the old
calibration parameters of the corresponding buffer.
If current confirmed buffer has no correspondence in the existing stored calibration
and this is not full, the current buffer is added to the existing stored calibration.
If the existing stored calibration is full (five calibration points), after confirming
the calibration point, the instrument will ask wich buffer will be replaced by
current buffer.
Press ARROW keys to select another buffer to be replaced.
Press CFM to confirm the buffer that will be replaced.
Press CAL or ESC to leave replace mode. In this case, the buffer will not be
memorised.
Note: The replaced buffer is not removed from calibration list and it can be
selected for the next calibration points.
22
WORKING WITH CUSTOM BUFFERS
If at least one custom buffer was set in SETUP menu, it can be selected for
calibration by pressing the ARROW keys. The Custom functional key will be
displayed.
Press Custom if you want to adjust the buffer value according with current
temperature.
Use the ARROW keys to change the buffer value.
Press Accept to accept new value or ESC to exit changing mode.
Note: Custom buffer value can be adjusted in a ±1.00 pH window, around
the set value.
WORKING WITH MILI pH BUFFERS
If calibration is invoked from mili pH range, the calibration buffer can be
modified in a ±0.020 pH range in according with the label on the calibration buffer.
Press Change to enter buffer adjust mode.
Use ARROW keys to change the buffer value.
Press Accept to accept new value or ESC to exit adjusting mode.
23
CLEAR CALIBRATION
Press Clear functional key when displayed or CLR key (HI 98180 &
HI 98181) to clear old calibrations.
All old calibrations, are cleared and the instrument continues calibration. The
points confirmed in current calibration are kept.
Note: If Clear calibration is invoked during the first calibration point, the
instrument returns to measurement mode.
ELECTRODE CONDITION
The display is provided with an icon, and a numeric value (unless the feature
is disabled) which gives an indication of the electrode status after calibration.
The “condition” remains active until the end of the calibration day.
Note: The electrode condition is evaluated only if current calibration includes
at least two standard buffers.
CLEAN ELECTRODE WARNING
Each time pH calibration is performed, the instrument internally compares the
new calibration with the one previously stored.
When this comparison indicates a significant difference, the “Clean electrode”
warning message is displayed to advise the user that the pH electrode may
need to be cleaned (see ELECTRODE CONDITIONING & MAINTENANCE section for
details, page 61).
After cleaning, perform a new calibration.
Note: If the calibration data are cleared, the comparison is done with the
default values.
24
p H BUFFER TEMPERATURE
DEPENDENCE
The temperature has an effect on pH. The calibration buffer solutions are
affected by temperature changes to a lesser degree than normal solutions.
During calibration the instrument will automatically calibrate to the pH value
corresponding to the measured or set temperature.

I S E CALIBRATION
(HI 981
84 & HI 981
98184
98188 55))
It is recommended to calibrate the instrument frequently, especially if high
accuracy is required.
The ISE range should be recalibrated:
• Whenever the ISE probe or ion charge is changed.
• At least once a week.
• After testing aggressive chemicals.
• When calibration alarm time out is expired- “CAL DUE” tags blinks (if
feature is enabled).
Due to electrode conditioning time, the electrode must be kept immersed a few
seconds to stabilize. The user will be guided step by step during calibration
with easy to follow tags on the LCD. This will make the calibration a simple and
error-free procedure.
PROCEDURE
Select the proper ISE probe in SETUP menu (only for HI 98185) or select the
proper Ion Charge (see SETUP for details, page 33).
Note: If ISE probe is not calibrated in at least one point, the “----” will be

30
GOOD LABORATORY PRACTICE (GLP)
GLP is a set of functions that allows storage and retrieval of data regarding the
maintenance and status of the electrode.
All data regarding pH, Rel mV or ISE calibration is stored for the user to review
when necessary.
EXPIRED CALIBRATION
The instrument is provided with a real time clock (RTC), in order to monitor
the time elapsed since the last pH calibration.
The real time clock is reset every time the instrument is calibrated and the
“expired calibration” status is triggered when the instrument detects a
calibration time out. The “CAL” “DUE” tags will start blinking to warn the
user that the instrument should be recalibrated.
The calibration time out can be set (see SETUP for details, page 33) from 1 to
7 days or can be disabled.
For example, if a 4 days time out has been selected, the instrument will issue
the alarm exactly 4 days after the last calibration.
However, if at any moment the expiration value is changed (e.g. to 5 days),
then the alarm will be immediately recalculated and appear 5 days after the
last calibration.
Notes: • When the instrument is not calibrated or calibration is cleared
(default values loaded) there is no “expired calibration”, and
the display always shows the “CAL” “DUE” tags blinking.
• When an abnormal condition in the RTC is detected, the instrument
forces the “expired calibration” status.
LAST pH CALIBRATION DATA
The last pH calibration data is stored automatically after a successful calibration.
To view the pH calibration data, press GLP when the instrument is in the pH
measurement mode.
The instrument will display a lot of data including calibration buffer, offset,
slope, electrode condition.
Note: Buffers displayed in video inverse mode are from previous calibrations.
The custom buffers are marked with an “*” on the right side of the buffer value.
“No user calibration” message is displayed if all calibration are cleared or
the instrument was not calibrated in the pH range.
31
LAST RELATIVE mV CALIBRATION DATA
Last Relative mV calibration data is stored automatically after a successful
calibration.
To view the Relative mV calibration data, press GLP key while in Relative mV
measurement mode.
The instrument will display the Relative mV GLP information: calibration date,
time and offset.
LAST ISE CALIBRATION DATA
Last ISE calibration data is stored automatically after a successful calibration.
To view the ISE calibration data, press GLP while in ISE measurement mode.
The instrument will display the ISE calibration information: calibration date,
time, slope, calibration status and electrode type.
Notes: • Press GLP or ESC at any moment and the instrument will return
to measurement mode.
• If calibration has not been performed, the instrument displays
“No user calibration” message.
• The calibration standards from previous calibration are displayed
in video inverse mode.

BATTERIES
RECHARGING/REPLACEMENT
The instrument is ready with rechargeable batteries inside.
First time you start working with the instrument or when the rechargeable
batteries are changed with new ones, perform the following procedure:
• Work with the instrument until the rechargeable batteries are fully discharged
• Perform a complete charging cycle (about 16hours).
Repeat this procedure 3 times.
It is recommended to recharge the rechargeable batteries as soon as the
battery indicator does not show full scale before starting in field measurements
or every time you finish your work with your instrument.
If the battery capacity is less than 20 % the serial communication and the
backlight feature are not available.
To replace the rechargeable batteries, follow the next steps:
• Turn OFF the instrument.
• Unscrew the screw from the bottom side of the instrument.
• Remove the battery holder and the old batteries.
• Insert four new 1.2V AA 1300 mAh NiMH rechargeable batteries in the
battery compartment while paying attention to the correct polarity.
• Push the battery holder and tighten the screws.
58
To recharge the rechargeable batteries, follow the next steps:
• Connect the 12VDC power adapter to the main line and to the main line of the
battery recharger. The front LED will turn ON.
• Place the instrument in the battery recharger case. A charging animation will
be displayed if the battery capacity is less than 100 %.
• The complete charging process takes about 16 hours.
Notes: • As the charging process is performed at low current, the instrument can be left on the recharger more than 16 hours, without
damaging the rechargeable batteries.
• It is recommended to turn off the instrument while recharging the
batteries. The measurements can be affected by the recharging
process.
• Batteries recharging must only take place in a non hazardous
area, using the HI 710042 inductive recharger.
WARNING:
Do not replace the rechargeable batteries with normal alkaline batteries.
Do not put ever the instrument with alkaline batteries inside on the recharger.
The manufacturer don’t assume any obligation for malfunctioning appeared
as a result of using alkaline batteries.
Note: The instrument is provided with the BEPS (Battery Error Prevention
System) feature, which automatically turns the instrument off when
the batteries level is too low to ensure reliable readings.

TEMPERATURE CORRELATION
FOR p H SENSITIVE GLASS
The resistance of glass electrodes partially depends on the temperature. The lower
the temperature, the higher the resistance. It takes more time for the reading to
stabilize if the resistance is higher. In addition, the response time will suffer to a
greater degree at temperatures below 25 ºC (77 ºF).
Since the resistance of the pH electrode is in the range of 50 – 200 Mohm, the
current across the membrane is in the pico Ampere range. Large currents can
disturb the calibration of the electrode for many hours.
For these reasons high humidity environments, short circuits and static discharges
are detrimental to a stable pH reading.
The pH electrode’s life also depends on the temperature. If constantly used at
high temperatures, the electrode life is drastically reduced.
Typical Electrode Life
Ambient Temperature
1 – 3 years
90 ºC (194 ºF)
Less than 4 months

Alkaline Error
High concentrations of sodium ions interfere with readings in alkaline
solutions. The pH at which the interference starts to be significant depends
upon the composition of the glass. This interference is called alkaline error and
causes the pH to be underestimated. Hanna’s glass formulations have the
indicated characteristics.

ELECTRODE CONDITIONING
& MAINTENANCE
Not present in gel electrodes.
PREPARATION PROCEDURE
Remove the electrode protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal
with electrodes and they will disappear when rinsed with water.
During transport tiny bubbles of air may have formed inside the glass bulb.
The electrode cannot function properly under these conditions. These bubbles
can be removed by "shaking down" the electrode as you would do with a glass
thermometer.
If the bulb and/or junction are dry, soak the electrode in HI 70300 Storage
Solution for at least one hour.
61
For refillable electrodes:
If the filling solution (electrolyte) is more than 2½ cm (1”) below the fill hole, add
HI 7082 or HI 8082 3.5M KCl Electrolyte Solution for double junction or HI 7071
or HI 8071 3.5M KCl+AgCl Electrolyte Solution for single junction electrodes.
For faster response, unscrew the fill hole screw during measurements.
For AmpHel ® electrodes:
If the electrode does not respond to pH changes, the battery run down and
the electrode should be replaced.
MEASUREMENT
Rinse the pH electrode tip with distilled water. Immerse the tip (bottom 4
cm /1½”) in the sample and stir gently for a few seconds.
For a faster response and to avoid cross-contamination of the samples, rinse
the electrode tip with a few drops of the solution to be tested, before taking
measurements.
See that the sleeve holes of the ORP probe are completly submerged.
STORAGE PROCEDURE
To minimize clogging and assure a quick response time, the glass bulb and the
junction of pH electrode should be kept moist and not allowed to dry out.
Replace the solution in the protective cap with a few drops of HI 70300 or
HI 80300 Storage Solution or, in its absence, Filling Solution (HI 7071 or
HI 8071 for single junction and HI 7082 or HI 8082 for double junction
electrodes). Follow the Preparation Procedure on page 61 before taking measurements.
Note: NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED WATER.
PERIODIC MAINTENANCE
Inspect the electrode and the cable. The cable used for connection to the
instrument must be intact and there must be no points of broken insulation on
the cable or cracks on the electrode stem or bulb. Connectors must be perfectly
clean and dry. If any scratches or cracks are present, replace the electrode.
Rinse off any salt deposits with water.
pH Probe Maintenance
For refillable electrodes:
Refill the reference chamber with fresh electrolyte (HI 7071 or HI 8071 for
single junction or HI 7082 or HI 8082 for double junction electrodes). Allow the
electrode to stand upright for 1 hour.
62
Follow the Storage Procedure above.
pH CLEANING PROCEDURE
• General
Soak in Hanna HI 7061 or HI 8061 General
Cleaning Solution for approximately ½ hour.
• Protein
Soak in Hanna HI 7073 or HI 8073 Protein
Cleaning Solution for 15 minutes.
• Inorganic
Soak in Hanna HI 7074 Inorganic Cleaning Solution
for 15 minutes.
Rinse with Hanna HI 7077 or HI 8077 Oil and Fat
• Oil/grease
Cleaning Solution.
IMPORTANT: After performing any of the cleaning procedures, rinse the
electrode thoroughly with distilled water, refill the reference chamber with
fresh electrolyte (not necessary for gel-filled electrodes) and soak the electrode
in HI 70300 or HI 80300 Storage Solution for at least 1 hour before taking
measurements.
