Overview

The measurement principle of GNST-SS232 online suspended solids sensor is based on infrared scattering light technology, which involves irradiating the sample solution with a beam of light and scattering it by the suspended solids in the solution. As shown in the figure below, the infrared light source emits light at a certain angle to the detection light, and the intensity of the light received by the detector is related to the suspended solids in the measured water body. Therefore, the concentration of suspended solids in the measured water body can be calculated by measuring the intensity of the scattered light.

Product Details

GNST-SS232 online suspended solids sensorUsing infrared light scattering method, the incident light enters the water and scatters on the surface of suspended particles. The intensity of the scattered light is detected on the light path at a certain angle to the incident light, and the concentration of suspended particles in the water is obtained by the proportional relationship between the scattered light intensity and the concentration of suspended particles.

Application field

The instrument is widely used in industries such as sewage treatment plant treatment process and discharge outlet water quality monitoring, other industrial wastewater treatment processes and discharge outlet water quality monitoring, and has received high praise from a large number of users.
