CONDUCTIVITY VERSUS

TEMPERATURE CHART

The conductivity of an aqueous solution is a 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 solutions 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 Celsius degrees at a particular
temperature, commonly as %/ºC.

The following table lists the temperature dependence of HANNA EC
calibration standards.
