HK-328 pH/ORP Analyzer, 0.00-14.00 pH (CAT#: STEM-AL-4130-ZJF)

HK-328 pH/ORP Analyzer is designed for laboratory or field analysis of pH and oxidation-reduction potential. The instrument measures pH and oxidation-reduction potential using electrochemical pH/ORP measurement. The documented operating or measurement range is 0.00-14.00 pH. Electronic control manages measurement, calculation, and display functions. The interface presents live readings, settings, and available status information. Specified analog, relay, or digital interfaces support integration with external systems where provided. Temperature compensation, calibration, alarm, cleaning, or storage functions are applied according to the model configuration. The sample path, sensor, or reaction module is arranged for the stated online, laboratory, or portable workflow. The instrument supports repeatable analysis within the documented sample and environmental limits.
