ZS-406 integrated online turbidity sensor is designed and manufactured using the principle of scattered light turbidity measurement. When a beam of light is incident on a water sample, the light is scattered by the turbidity substance in the water sample, and the intensity of the scattered light in the direction perpendicular to the incident light is measured and compared with the internal calibration value to calculate the turbidity in the water sample. Degree, linearized to output the final value.

90° angle scattered light principle, built-in temperature sensor
Support RS-485, Modbus/RTU protocol
Optical fiber structure, strong resistance to external light interference
Infrared LED light source with high stability
IP68 protection, water depth within 20 meters
Convenient, fast, stable, and easy to maintain
