Testing coolants and other aqueous samples.
The electrical conductivity of a liquid sample is determined by the resistance of the solution between two electrodes within the meter.
It essentially measures how well electricity flows in a given solution.
Generally the results tell us about the levels of conductive ions from salts and other inorganic material within the sample. It can be a good indicator of the presence of corrosion-causing compounds and impurities in a sample.
