Details

DiSTs are rugged and reliable pocket-sized testers that offer quick and accurate readings of conductivity. The DiST® family of testers is widely used for monitoring EC 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 better repeatability in measurements, since they do not oxidize. An amperometric measurement of EC 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 affect accuracy. The DiSTs non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results. When calibration is needed, simply submerge the electrode tip into calibration solution and adjust the trimmer on the side of the tester.
