The DiST® family of testers is widely used for monitoring EC/TDS in drinking water, water conditioning, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquaculture and aquariums, hydroponics, and the printing industry. These testers feature an amperometric graphite electrode that provides improved repeatability in measurements since they do not oxidize.

An amperometric measurement of EC/TDS is based on Ohm’s Law, I = V/R, where R depends on the distance between two pins and their surface. Oxidation changes both the distance and surface, which will directly affect accuracy. DiST® non-oxidizing graphite pins can provide an optimal surface for accurate, dependable results. When calibration is needed, simply submerge the electrode tip into the calibration solution and the meter will auto-calibrate.
