Temperature Source
To set the
temperature source:
Note:
The
HI 76312
sensor has an integrated temperature sensor and will provide the best conductivity
measurement. Use Automatic to use sensor or Manual. When manual, the value will have to be adjusted using
when in measurement mode.

Temperature Compensation
The user can choose from the following options:
Linear - the meter will automatically compensate the conductivity using the following formula:
where:
C
ref
- conductivity at reference temperature
C
I
- conductivity at temperature of measurement
α
- compensation coefficient
T
I
- temperature in °C
T
ref
- reference temperature
Non-Linear - recommended for measuring the conductivity of the natural water in accordance with the ISO-788-
1985. It provides compensation in the range of 60 to 1000 µS/cm over a temperature range of
0 - 35 °C.
Disabled - the meter will display the Absolute conductivity with no temperature compensation.
