HK-1351 Online Dissolved Oxygen Monitor, 0-20 mg/L (CAT#: STEM-AL-4108-ZJF)

HK-1351 Online Dissolved Oxygen Monitor is designed for online process monitoring of dissolved oxygen. The instrument measures dissolved oxygen using membrane-electrode electrochemical detection. The documented operating or measurement range is 0-20 mg/L. 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.
