HK-368 Acid/Alkali Concentration and Conductivity Analyzer, 0-2000 mS/cm (CAT#: STEM-AL-4111-ZJF)

HK-368 Acid/Alkali Concentration and Conductivity Analyzer is designed for laboratory or field analysis of conductivity and related water-quality values. The instrument measures conductivity and related water-quality values using the analytical or process method documented for the model. The documented operating or measurement range is 0-2000 mS/cm. 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.
