Infrared Turbidity Sensor with Auto Brush 0.01-3000NTU RS485 MODBUS

Infrared Turbidity Sensor with automatic brush For water treatment plant
 

The Daruifuno OPTU201 employs a sophisticated infrared absorption and scattering method to measure turbidity with high accuracy. The sensor uses a stable 860nm LED infrared light source to emit light into the water. As light passes through, suspended particles cause it to scatter. The sensor's detectors then measure both the scattered and absorbed light. By analyzing the ratio and intensity of this scattered light, the sensor precisely calculates the turbidity of the water. This advanced principle ensures stable data, reliable performance, and high-precision measurement, even in challenging conditions.
