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.
HI98304P can measure EC upto 19.99 mS/cm
These testers feature an amperometric graphite electrode that provides better 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 affect accuracy. The DiST’s non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results.
When calibration is necessary, simply submerge the electrode tip into calibration solution (5.00 mS/cm or 12.88 mS/cm) and adjust the trimmer on the side of the tester.
