Zhongang applies fiber optic technology to turbidity sensors, making the sensors have better repeatability and stability, and less susceptible to the influence of ambient light. The automatic cleaning brush in conjunction with the sensor can effectively eliminate bubbles, reduce the impact of contamination on measurement, prolong maintenance cycles, and maintain excellent stability even during long-term online use.

Application areas: rainwater, municipal sewage, industrial wastewater, surface water, drinking water, seawater, natural water bodies, water treatment industry, industrial process control, and other fields.
