SZ-HJ-DO

Product catalog summary
Summary:
The SZ-HJ-DO series is an online dissolved oxygen sensor that utilizes a battery-type oxygen sensing electrode and an internal electrode for automatic temperature compensation and digital signal conversion. It offers rapid response, low maintenance, and real-time online measurement capabilities. The sensor supports the Modbus RTU (485) protocol, operates on a 24V DC power supply, and uses a four-wire mode for easy integration into sensor networks.
Features:
  • Stable long-term operation with an online oxygen sensing electrode.
  • Built-in temperature sensor for real-time temperature compensation.
  • RS485 signal output with strong anti-interference capability and an output distance of up to 500 meters.
  • Standard Modbus RTU (485) communication protocol.
  • Simple operation with remote settings and calibration capabilities.
  • Powered by a 24V DC power supply.
