Make quick and accurate readings of conductivity or TDS with TDS meters from Grainger. They are widely used to monitor EC/TDS in drinking water, water conditioning, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquaculture and aquariums, hydroponics and the printing industry. TDS meters feature an amperometric graphite electrode that provides better repeatability since they do not oxidize.Close
