BWS-OW Oil-in-Water Online Sensor

The Oil-in-Water Online Sensor is a water quality online analysis instrument developed based on the OSA optical water quality analysis platform. Utilizing a high-sensitivity photoelectric sensor to capture faint fluorescence signals, it converts these signals into oil concentration measurements. Designed with a digitalized and intelligent sensor philosophy, it automatically compensates for the effects of voltage fluctuations, component aging, and temperature variations on measurements. With RS485 output supporting standard Modbus protocol, it enables easy networking and is widely used in surface water monitoring and related industries.

●High-brightness LED light source for long-term stable operation.
