What is it used for?
Testing coolants and other aqueous samples.
How does it work?
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.
What do the results tell us?
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.
