The Economic RS485 Digital Optical Fluorescence Dissolved Oxygen Sensor utilizes advanced fluorescence technology for precise dissolved oxygen measurement in various water applications. This DO probe offers reliable performance with minimal maintenance requirements.

This sensor employs the fluorescence quenching method where blue light excites fluorescent material, causing red light emission. The dissolved oxygen concentration is determined by measuring the fluorescence lifetime, providing accurate readings without oxygen consumption during operation.

• No oxygen consumption during measurement
• Stable and reliable data output
• Minimal interference from other substances
• Simple installation and calibration process
• Anoxic water calibration and air calibration options
• Robust IP68 waterproof construction

Widely used for dissolved oxygen monitoring in:

• Wastewater treatment plants
• Water supply facilities and monitoring stations
• Surface water systems (rivers, lakes)
• Drinking water monitoring
• Environmental monitoring systems
• Aquaculture operations
• Industrial process monitoring
