Product Features:

  • Up to 6 sensors can be installed.
  • The sensors are digital, with strong anti-interference capabilities and long transmission distance.
  • Direct immersion measurement without the need for sampling and pre-processing.
  • Digital automatic cleaning brush for plug-and-play functionality.
  • All electrodes can be replaced by the user on-site, facilitating maintenance.
  • Low operating costs, no reagents, no pollution, a truly environmentally friendly product.
  • Calibration and configuration information are stored in independent sensors, allowing for convenient maintenance of calibration.
  • Universal platform with a unified interface, supporting plug-and-play functionality for any Dongrun sensor.
  • Protection against reverse polarity of sensor power supply.
  • Each sensor compartment is designed separately, so that a leakage or failure in one sensor does not affect the operation of others, and all compartments have internal humidity detection alarm function.
  • Support for active and passive low power modes.
