SH-SS200 Total Suspended Solids digital sensor
Overview
SH-SS-200 Total Suspended Solids digital sensor is an intelligent device to measure the concentration of suspended matter in the water body. The sensor adopts infrared light scattering method, i.e. light scattering occurs on the surface of suspended particles after the incident light enters into the water body, the intensity of the scattered light is detected on the light path which is in a certain angle direction with the incident light, and the concentration of suspended matter in the water body is obtained through the proportional relationship between the intensity of the scattered light and the concentration of suspended matter.
Product features
