DiST’s are rugged and reliable pocket-sized testers
that offer quick and accurate readings of
conductivity or TDS.
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 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 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 and adjust
the trimmer on the side of the tester.
