My conductivity meter has a temperature compensation option called ‘Non-linear function’. What does this mean and should I use it for my measurements ?

by

Many better quality conductivity meters are programmed with this option for environmental testing.  If the conductivity meter is programmed with a non-linear temperature compensation function that conforms to ISO 7888, this type of temperature compensation will give a reasonable estimate of what your sample’s conductivity value would be at 25ºC.  There are strict conditions for applying ISO 7888 temperature compensation – the sample conductivity must be between 60 – 1,000 µS/cm and the measurement temperature must be between 0 – 35ºC.

More detailed technical information on the effects of temperature on conductivity measurement is given in our Technical Paper: The Effect of Temperature on Conductivity Measurement.
