Economic RS485 Digital Optical Fluorescence Dissolved Oxygen Sensor DO Probe

Digital Optical Fluorescence Water Dissolved Oxygen Sensor DO RS485 sensor

>>Technical Parameter

The dissolved oxygen sensor employs the fluorescent method to measure dissolved oxygen. It emits blue light that illuminates the fluorescent layer, exciting the fluorescent material to emit red light. The oxygen concentration is inversely proportional to the time it takes for the fluorescent material to return to its ground state. This measurement method eliminates oxygen consumption during operation, ensures stable and reliable data output, avoids interference, and features simple installation and calibration.

The product is widely used for dissolved oxygen monitoring in wastewater treatment plants, water supply facilities, monitoring stations, surface water systems, aquaculture operations, industrial applications, and other related fields.
