WATER QUALITY SENSOR

The Dissolved Oxygen (DO) Sensor?? leverages cutting-edge fluorescence quenching technology to deliver highly accurate and reliable dissolved oxygen measurements. Based on the principle that oxygen molecules quench the fluorescence of a specially coated film when exposed to excitation light, this sensor calculates oxygen concentration by measuring fluorescence decay time. Combined with ??simultaneous temperature measurement??, it provides real-time data via RS485 and 4–20mA outputs. Engineered for minimal maintenance, it boasts a ??lifespan exceeding 2 years?? without recalibration, making it ideal for demanding environments such as chemical plants, aquaculture systems, and wastewater treatment facilities.
