ZS-408-S Online Turbidity Sensor
ZS-408S integrated online turbidity sensor is designed and manufactured using the principle of scattered light turbidity measurement. When a beam of light enters the water sample, the light is scattered by the turbidity material in the water sample. By measuring the scattered light intensity in the vertical direction to the incident light and comparing it with the internal calibration value, the turbidity in the water sample is calculated. degree, and output the final value after linearization.
90° angle scattered light principle, built-in temperature sensor
Support RS-485, Modbus/RTU protocol, 4-20mA current output
Optical fiber structure, strong resistance to external light interference
Infrared LED light source, high stability
IP68 protection, water depth within 20 meters
Convenient, fast, stable and easy to maintain
