The Ultra Pure Water (UPW) Tester HI98309 from Hanna Instruments is a high-precision pocket tester designed for monitoring the purity of deionized, distilled, and ultra-pure water. It measures in increments as small as 1/1000th of micro-Siemens (µS), ensuring rapid detection of even minute traces of contamination. This tester features an amperometric graphite electrode that reduces polarization effects, offering superior repeatability compared to traditional steel probes. Its factory calibration ensures immediate use with laboratory-grade resolution, and it includes automatic temperature compensation for consistent readings in varying environments.
