General Description & Intended Use
HI98129
&
HI98130
are compact pH, EC/TDS and temperature
testers. They feature a two-buttons operation system and are easy
to use. The compact and waterproof casing is designed to float if
accidentally dropped in water. The testers measure temperature in
both °C and °F. All pH and EC/TDS measurements are temperature
compensated automatically (ATC). EC/TDS measurements have
user-selectable EC/TDS conversion factor (CONV) and temperature
compensation coefficient (ß). The testers display a stability tag ( )
that will disappear once the reading has stabilized.
Battery level and low-battery indicator are clearly displayed on
the LCD to alert the user in the event that low battery power could
adversely affect readings.
BEPS (Battery Error Prevention System) Testers will automatically
shut off if there is not enough power to get an accurate measurement.
pH Probe:
HI98129
&
HI98130
are supplied together with
HI73127
pH replaceable electrode with a stainless steel round connector and
extendable cloth junction. This design has no pins to line up or that
can break.
Temperature Sensor:
The stainless steel temperature sensor
facilitates faster and more accurate temperature measurement.

Operational Guide
Turning the Tester ON / OFF
Press and hold /MODE. All LCD segments will be displayed for a
few seconds followed by battery life percentage indicator. To turn the
tester off, from measurement mode, press /MODE. “OFF” will be
displayed on the second LCD line and then the tester will turn off.
HOLD Mode
From measurement mode, press and hold SET/HOLD until “HOLD” is
displayed. pH, EC/TDS or temperature readings will be frozen on the
LCD. Press either buttons to resume measurement mode.
Setup
Setup mode allows the selection of temperature unit and pH buffer set. To
enter the setup mode, select pH mode and press /MODE until “TEMP”
and the current temperature unit are displayed (e.g. “TEMP °C”). Then:
• Press SET/HOLD to select temperature unit. After the temperature
unit has been selected, press /MODE to select the buffer set. To
return to measurement mode, press /MODE twice.
• After setting the temperature unit, the tester will display the current
buffer set: “pH7.01 BUFF” (for pH 4.01/7.01/10.01) or “pH6.86
BUFF” (for NIST pH 4.01/6.86/9.18). Press SET/HOLD to change
the buffer set and press /MODE to resume measurement mode.
pH Calibration & Measurement
It is recommended to calibrate the tester frequently, especially if high
accuracy is required. More frequent calibrations may be required depending
on the type of sample being tested. The tester should be recalibrated:
• whenever the pH electrode is replaced
• at least once a month
• after testing aggressive samples
From measurement mode, press and hold /MODE until “CAL” is
displayed. The tester enters calibration mode and displays “pH 7.01
USE” or “pH 6.86 USE”, if NIST buffer was selected. Buffer value
will be displayed on the first LCD line and “REC” message will be
displayed on the second line. If used buffer was not valid, “USE”
message will be displayed for 12 seconds and replaced by “WRNG”
indicating measured sample is not valid.
• For one-point calibration using pH 4.01, 10.01 or 9.18 buffer solution,
once the reading has stabilized, the tester automatically accepts the
calibration point. Accepted buffer point and “OK 1” message are
displayed and then the tester returns to measurement mode.
• For one-point calibration using pH 7.01 (or 6.86) buffer solution,
press /MODE after calibration point has been accepted. The
tester will display “pH 7.01” (or “pH 6.86”) and “OK 1” and then
return to measurement mode.
• For a two-point calibration using pH 7.01 (or pH 6.86) buffer solution,
after the first calibration point has been accepted, “pH 4.01 USE” will
be displayed for 12 seconds (unless a valid buffer is recognized).
• If valid buffer solution is recognized (pH 4.01, 10.01 or 9.18),
the calibration point is accepted and the accepted value and “OK
2” are displayed. The tester then returns to measurement mode.
• If no valid buffer solution is recognized, “WRNG” message is displayed.
Note:
When the calibration procedure is completed, the “CAL”
tag is turned on.
Exiting Calibration & Resetting Default Values
• When in calibration mode, it is possible to exit calibration
procedure by pressing /MODE, before first-point calibration
has been accepted. The tester displays “ESC” and returns to
measurement mode and last calibrated data.
• When in calibration mode, it is possible to clear a previous
calibration and return to default values by pressing SET/HOLD,
before the first calibration point has been accepted. The tester
displays “CLR” on the second LCD line, “CAL” tag dissappears and
tester returns to default calibration.
