Product Overview

The SUP-DO7018 Optical Dissolved Oxygen Sensor utilizes advanced fluorescence quenching technology to provide highly accurate and reliable dissolved oxygen measurement without consuming oxygen during operation. Unlike conventional electrochemical sensors, it requires no electrolyte replacement, is unaffected by flow rate, and offers excellent long-term stability with minimal maintenance.
Featuring automatic temperature compensation, RS485 Modbus communication, and an IP68-rated titanium housing, the SUP-DO7018 is ideal for continuous monitoring in aquaculture, wastewater treatment, environmental monitoring, food & beverage processing, and chemical industries.

Key Features

  • Advanced fluorescence quenching technology provides stable and accurate dissolved oxygen measurement without membrane or electrolyte replacement.
  • No oxygen consumption, no electrolyte replacement, and minimal routine maintenance reduce operating costs.
  • Built-in NTC temperature sensor automatically compensates for temperature variations to improve measurement accuracy.
  • Provides fast response (approximately 10 seconds) with annual drift below 1%, ensuring long-term measurement stability.
  • Supports RS485 communication with Modbus RTU protocol for easy integration with PLC, DCS and SCADA systems.
  • Replaceable sensor cap simplifies maintenance and extends product service life.

FAQ

What is the SUP-DO7018 used for?

The SUP-DO7018 is designed for continuous dissolved oxygen monitoring in aquaculture, wastewater treatment, rivers and lakes, marine environments, food & beverage processing, and chemical industries.

Why choose an optical dissolved oxygen sensor instead of an electrochemical sensor?

Optical dissolved oxygen sensors require no electrolyte replacement, consume no oxygen during measurement, and are less affected by flow rate or hydrogen sulfide, resulting in lower maintenance and improved long-term stability.

Does the sensor require frequent calibration?

No. The SUP-DO7018 supports one-point and two-point calibration and is designed for low drift and minimal maintenance under normal operating conditions.

Does the sensor support industrial automation systems?

Yes. The sensor supports RS485 communication with Modbus RTU protocol, making it compatible with PLC, DCS, and SCADA systems.
