The conductivity of an aqueous solution is the measure of its ability to
carry an electrical current by means of ionic motion.
The conductivity invariably increases with increasing temperature.
It is affected by the type and number of ions in the solution and by
the viscosity of the solution itself. Both parameters are temperature
dependent. The dependency of conductivity on temperature is
expressed as a relative change per degree Celsius at a particular
temperature, commonly as percent per °C.
For manual temperature compensation, refer to the following chart:
For instance, the conductivity values of the calibration solutions at
25°C are 12880 µS/cm, 1413 µS/cm or 5000 µS/cm when using
HI 7030, HI 7031 or HI 7039, respectively.
At 20°C, the values are 11670 µS/cm, 1278 µS/cm or
4523 µS/cm, respectively.
With the solutions at 30°C, the values are 14120 µS/cm, 1548 µS/cm
or 5479 µS/cm, respectively.
