 Many people notice another value than expected immediately after calibration in a KCl solution. Here is explained why. Many people notice another value than expected immediately after calibration in a KCl solution. Here is explained why.
  
-A Conductivity meter can reflect the absolute conductivity (i.e. not temperature compensated) or the relative conductivity which is the recalculated absolute measurement towards the reference temperature. To obtain the relative value, the meter is using a certain temperature dependent method to convert the absolute measurement. The Consort meters make use of the general accepted international standard **EN27 888** to do so. This temperature compensation assumes the measured value is behaving as a **natural water**. The measured products mostly have another temperature behaviour. This leads to calculation differences, which increase when the temperature difference with the reference temperature is larger.+A Conductivity meter can reflect the absolute conductivity (i.e. not temperature compensated) or the relative conductivity which is the recalculated absolute measurement towards the reference temperature.
