Product Overview

The SUP-DO700 Optical Dissolved Oxygen Meter uses advanced fluorescence technology to provide accurate, stable dissolved oxygen measurement without consuming oxygen during testing. Unlike traditional electrochemical sensors, it requires minimal maintenance, offers excellent long-term stability, and is ideal for continuous monitoring in water treatment, aquaculture, and industrial process applications.

Key Features

  • Provides accurate dissolved oxygen measurement without oxygen consumption during testing.
  • No electrolyte replacement or membrane maintenance, reducing operating costs.
  • Factory calibrated with stable performance and typically requires calibration only once per year.
  • Built-in NTC temperature compensation improves measurement accuracy across varying conditions.
  • Supports MODBUS RS485 communication and dual 4–20 mA analog outputs for PLC/DCS integration.
  • IP68 optical sensor and IP65 transmitter designed for demanding industrial environments.
