The HI98308 Pure Water tester is a rugged and reliable pocket-sized tester that offers quick and accurate readings. The HI98308 Pure Water tester features graphite electrodes to reduce polarization effects and an exposed temperature probe for fast response when compensating for temperature changes. Manual calibration is performed to a single point.

  • Exposed temperature sensor
  • Very low range EC (0.0 to 99.9 μS/cm)
  • Single point manual calibration
The HI98308 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 non-oxidizing 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 adjust the trimmer on the side of the tester.
