GENERAL DESCRIPTION
HI 98129 and HI 98130 are waterproof pH, EC/TDS
and temperature meters. The housing has been completely sealed against humidity and designed to float.
All pH and EC/TDS readings are automatically temperature compensated (ATC), and temperature values
can be displayed in °C or °F units.
For EC/TDS readings, the EC/TDS conversion factor
(CONV) is selectable by the user, as well as the
temperature compensation coefficient β (BETA).
The meters can be calibrated at one or two points for
pH (with auto-buffer recognition and against five
memorized buffer values), and at one point for EC/
TDS.
Measurements are highly accurate with a unique
stability indicator right on the LCD.
A low battery symbol warns the user when the batteries are to be replaced. In addition the Battery Error
Prevention System (BEPS) avoids erroneous reading
caused by low voltage level by turning the meter off.
The HI 73127 pH electrode, supplied with the meters,
is interchangeable and can be easily replaced by the
user.
The stainless steel encapsulated temperature sensor
facilitates faster and more accurate temperature measurement and compensation.

Recommendations for Users
Before using this product, make sure that it is entirely suitable for the environment in which it is used. Operation of
this instrument in residential areas could cause unacceptable interferences to radio and TV equipment.
The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times.
During operation, ESD wrist straps should be worn to avoid
possible damage to the electrode by electrostatic discharges.
Any variation introduced by the user to the supplied equipment may degrade the instrument’s EMC performance.
To avoid electrical shock, do not use this instrument when
voltages at the measurement surface exceed 24 VAC or 60
VDC. To avoid damages or burns, do not perform any measurement in microwave ovens.

OPERATIONAL GUIDE
To turn the meter on and to check battery status
Press and hold the MODE button for 2-3 seconds. All
the used segments on the LCD will be visible for a few
seconds, followed by a percent indication of the
remaining battery life. Eg. % 100 BATT.
Calibration procedure
From measurement mode, press and hold the MODE
button until CAL is displayed on the lower LCD.
Release the button. The LCD will display pH 7.01 USE
or pH 6.86 USE (if you have selected the NIST buffer
set). The CAL tag blinks on the LCD.
To change the EC/TDS conversion factor (CONV)
and the temperature compensation coefficient β
(BETA)
• From measurement mode, press and hold the
MODE button until TEMP and the current temperature unit are displayed on the lower LCD. Eg. TEMP
°C.
• Press the MODE button again to show the current
conversion factor. Eg. 0.50 CONV.
• Press the SET/HOLD button to change the conversion factor.
• Press the MODE button to show the current temperature compensation coefficient β. Eg. 2.1 BETA.
• Press the SET/HOLD button to change the temperature compensation coefficient β.
• Press the MODE button to return to normal measuring mode.
Remove the probe by rotating it counterclockwise and
then pulling it out.

To change the temperature unit
To change the temperature unit (from °C to °F), from
measurement mode, press and hold the MODE button until TEMP and the current temperature unit are
displayed on the lower LCD. Eg. TEMP °C.
Use the SET/HOLD button to change the temperature
unit, and then press MODE button twice to return to
normal measurement mode.
bration) or pH 6.86 BUFF (for NIST 4.01/6.86/9.18
calibration).
• Press the SET/HOLD button to change the buffer
value.
• Press the MODE button to return to normal measuring mode.
To freeze the display
Press the SET/HOLD button for 2-3 seconds until
HOLD appears on the secondary display.
Press either button to return to normal mode.
To turn the meter off
Press the MODE button while in normal measurement
mode. OFF will appear on the lower part of the
display. Release the button.
Notes
Notes:
• Before taking any measurement make sure the
meter has been calibrated.
• To clear a previous calibration, press the MODE
button after entering the calibration mode. The lower
LCD will display ESC for 1 second and the meter will
return to normal measurement mode. The CAL symbol
on the LCD will disappear. The meter will be reset to
the default calibration.
• If measurements are taken in different samples
successively, rinse the probe thoroughly to eliminate
cross-contamination; and after cleaning, rinse the
probe with some of the sample to be measured.
• For a single-point pH calibration, place the electrode
in any buffer from the selected buffer set (eg. pH 7.01
or pH 4.01 or pH 10.01). The meter will recognize
the buffer value automatically.
If using pH 4.01 or pH 10.01, the meter will display
OK for 1 second and then return to measurement
mode.
If using pH 7.01, after recognition of the buffer the
meter will ask for pH 4.01 as second calibration
point. Press the MODE button to return to measurement mode or, if desired, proceed with the 2-point
calibration as explained below.
Note
Note: It is always recommended to carry out a twopoint calibration for better accuracy.
• For a two-point pH calibration, place the electrode
in pH 7.01 (or 6.86 if you have selected the NIST
buffer set). The meter will recognize the buffer value
and then display pH 4.01 USE.
Rinse the electrode thoroughly to eliminate crosscontamination.
Place the electrode in the second buffer value (pH
4.01 or 10.01, or, if using NIST, pH 4.01 or 9.18).
When the second buffer is recognized, the LCD will
display OK for 1 second and the meter will return to
normal measurement mode.
pH MEASUREMENTS & CALIBRATION
The CAL symbol on the LCD means that the meter is
calibrated.
Taking measurements
Select the pH mode with the SET/HOLD button.
Submerge the electrode in the solution to be tested.
The measurements should be taken when the stability
symbol Ÿ on the top left of the LCD disappears.
EC/TDS MEASUREMENTS & CALIBRATION
The pH value automatically compensated for temperature is
shown on the primary LCD
while the secondary LCD shows
the temperature of the sample.
Calibration buffer set
• From measurement mode, press and hold the
MODE button until TEMP and the current temperature unit are displayed on the lower LCD. Eg. TEMP
°C.
• Press the MODE button again to show the current
buffer set: pH 7.01 BUFF (for 4.01/7.01/10.01 cali-
Taking measurements
Select either EC or TDS mode with the SET/HOLD
button.
Submerge the probe in the solution to be tested. Use
plastic beakers to minimize any electromagnetic interferences.
The measurements should be taken when the stability
symbol Ÿ on the top left of the LCD disappears.
The EC (or TDS) value automatically compensated for temperature
is shown on the primary LCD
while the secondary LCD shows
the temperature of the sample.
Calibration procedure
• From measurement mode, press and hold the
MODE button until CAL is displayed on the lower
LCD.
• Release the button and immerse the probe in the
proper calibration solution: HI7031 (1413 µS/cm) for
HI98129 and HI7030 (12.88 mS/cm) for HI98130.
• Once the calibration has been automatically performed, the LCD will display OK for 1 second and the
meter will return to normal measurement mode.
• Since there is a known relathionship between EC
and TDS readings, it is not necessary to calibrate the
meter in TDS
The CAL symbol on the LCD means that the meter is
calibrated.
pH ELECTRODE MAINTENANCE
• When not in use, rinse the electrode with water to
minimize contamination and store it with a few drops
of storage (HI 70300) or pH 7 (HI 7007) solution in
the protective cap after use. DO NOT USE DISTILLED
OR DEIONIZED WATER FOR STORAGE PURPOSES.
• If the electrode has been left dry, soak in a storage
or pH 7 solution for at least one hour to reactivate it.
• To prolong the life of the pH electrode, it is
recommended to clean it monthly by immersing it in
the HI 7061 cleaning solution for half an hour.
Afterwards, rinse it thoroughly with tap water and
recalibrate the meter.
Insert a new pH electrode following the above instructions in reverse order.
BATTERY REPLACEMENT
The meter displays the remaining battery percentage
every time it is switched on. When the battery level is
below 5%, the - + symbol on the bottom left of the LCD
lights up to indicate a low battery condition. The batteries must be immediately replaced. If however the battery
level is so low as to cause erroneous reading, the Battery
Error Prevention System (BEPS) will automatically turn
the meter off.
To change the batteries, remove the 4 screws located on
the top of the meter.
Once the top has been removed, carefully replace the 4
batteries located in the compartment while paying attention to their polarity.
Replace the top, making sure that the gasket is properly
seated in place, and tighten the screws.
