A tester measures drinking water from taps or municipal supplies to ensure no contaminants (bacteria, fungi, chemicals, metals).
By using a TDS meter, you can determine the amount of tritium in water. A TDS meter can be used for accurate measurements of substances with a high activity level, such as water.
People can use it to measure conductivity levels and identify hazardous substances. TDS meters require calibrated electrodes, so if you are going on vacation with no family, make sure you bring all the necessary equipment!
It cannot detect other contaminants such as metals and bacteria because they are not soluble. Consider a water testing kit instead if you want more clarity or precision than what TDS meters provide.
