pH Meters
|
A great measurement tool for testing water or pH levels in other substances is a digital pH meter. It eliminates the need to use pH test strips and can give very accurate and quick measurements.
A digital pH meter is used first by calibrating the meter to a set buffer solution with a verified pH level. This is done two to three times at different pH levels. Then you just insert the pH meter into your test solution and it will give an accurate measurement of the pH level.
Several pH meters can also measure temperature, electrical conductivity, and TDS (total dissolved solids) depending on the model.
