Testing coolants and other aqueous samples.
Total dissolved solids (TDS) is a measure of the combined dissolved content of all inorganic and organic substances contained in a liquid in a variety of forms using conductivity, whereby the resistance of the solution between two electrodes is determined to give a TDS value.
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.
