TDS Tester


  • Graphite sensor for enhanced repeatability
  • Complete with protective cap, screwdriver, batteries
  • Simple 1 point Calibration
  • Range: 0-1999 ppm
  • Hanna DiST1
  • Accuracy: +/- 2% F.S.

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.

This tester features an amperometric graphite electrode that provides better repeatability in measurements since they do not oxidize. An amperometric measurement of TDS is based on OhmÆs 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 DiSTÆs non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results.
