Pure Water Tester (0.0 - 99.9 µS/cm) - HI98308

Ships within 1-2 Business Days

The HI98308 Pure Water Test (PWT) uses a conductometric measurement to determine the purity of distilled or demineralized water in laboratory or industrial environments.

  • 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 for better measurement repeatability. The non-oxidizing graphite pins provide an optimal surface for accurate, dependable results. When calibration is needed, submerge the electrode tip into calibration solution and adjust the trimmer on the side of the tester.

PWT is suited for all areas where distilled, demineralized or pure water is used. This tester is housed in durable casing that provides excellent protection against harsh industrial environments.
