Description
This Pool Line Tester features an amperometric graphite electrode that provides improved repeatability in measurements, since it does not oxidise. An amperometric measurement of EC/TDS is based on Ohm’s Law l + V/R, where R depends on the distance between two pins and their surface. Oxidation changes both the distance and surface, which will directly affect accuracy. The non-oxidising 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 the meter will auto calibrate. Features Waterproof Automatic temperature compensation (ATC) Automatic one-point calibration Measurement Stability Indicator Temperature measurement Range 0.00 to 20.00mS/cm Resolution 0.01 mS/cm Accuracy ±2% F.S.
