PRELIMINARY EXAMINATION
GENERAL DESCRIPTION
HI 83140 is an hand-held pH/mV/°C meter designed for
simplicity of use in taking pH, mV (ORP) and temperature
measurements.
The pH, mV and °C ranges are easily selected using a
membrane keyboard on the front panel.
Calibration procedure is very simple and adjustments are
easily made with two trimmers on the front panel.
The meter is also provided with Probe Check feature, which
allows the user to easily check the probe calibration status
at any time.
The built-in temperature sensor in the pH electrode allows
automatic temperature compensation of pH readings.
Moreover HI 83140 has been designed with a low battery
detector feature and a lightweight ABS plastic housing.
FUNCTIONAL DESCRIPTION
SPECIFICATIONS
1) DIN connector for combination pH or ORP electrode.
2) Liquid Crystal Display.
3) Green and Red LED’s for Probe Check.
4) Check key.
5) mV key, to display the mV (ORP) readings when
using an ORP electrode or the mV equivalent to pH
values when using a pH electrode.
6) OFFSET trimmer for pH calibration.
7) SLOPE trimmer for pH calibration.
8) °C key, to display the temperature measurement.
9) pH key, to display the pH value.

(*) The max. operating temperature of the HI 121700 pH electrode is 80ºC.
To perform measurements at higher temperature use adequate electrodes.
BATTERY REPLACEMENT
When the battery becomes weak, the
meter displays a blinking additional deci-
mal point on the left side of the LCD.
When the low battery indicator appears only a few hours of
battery life is remaining. A low battery level may also result
in unreliable measurements. It is recommended to replace
the battery soon.
Unscrew the 3 screws on the back of the meter, remove the
battery cover and replace the battery while paying atten-
tion to its polarity.
Replacement must only take place in a non-hazardous area
using an alkaline 9V battery.
