HM Digital Water Quality Meters and Testers

HM Digital manufactures economical hand-held and in-line water quality meters and monitors. They can be used for residential and light commercial applications, such as measuring if Reverse Osmosis membranes operate properly. Typical water meters measure TDS, pH, electrical conductivity, temperature and more. TDS meters measure total dissolved solids (TDS) levels. A TDS meter is an effective way to compare rejection rates and gauge reverse osmosis membrane, water filter and water purification performance.
