The DiST® family are rugged and reliable
pocket-sized testers that o+er 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.
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 a+ect accuracy. DiST® non-oxidizing
graphite pins are able to provide an optimal
surface for accurate, dependable results.
