Product Overview

The SUP-DM2800 is an industrial online dissolved oxygen analyzer designed for continuous monitoring of dissolved oxygen concentration in water treatment and process control applications.
It simultaneously measures dissolved oxygen, oxygen saturation, oxygen partial pressure, and temperature while providing automatic temperature compensation for improved accuracy. With isolated analog output, MODBUS RTU communication, programmable alarms, and multiple calibration functions, the analyzer is ideal for wastewater treatment, environmental monitoring, power plants, food processing, and aquaculture systems.

Key Features

  • Simultaneously measures dissolved oxygen, saturation, oxygen partial pressure, and temperature for comprehensive process monitoring.
  • Supports both automatic and manual temperature compensation to improve measurement accuracy under changing process conditions.
  • Provides isolated 4–20 mA analog output and MODBUS RTU communication for easy integration with PLC and SCADA systems.
  • Supports convenient air calibration and zero-point calibration for reliable long-term measurement performance.
  • Configurable high and low alarm relays help operators respond quickly to abnormal dissolved oxygen conditions.
  • Built for stable 24/7 online monitoring in demanding industrial and municipal water treatment environments.
