Anti-interference.

Note: Brush the optical glass surface of the sensor with a brush every two months.

Features:

Good antifouling property: the optical surface of the sensor adopts nano antifouling materials with self-cleaning function. The surface of the sensor is still very new after continuous use in the sewage environment for 2 months;

Strong anti-interference ability: the sensor adopts modulated light source, which can be used directly without special shading equipment in the environment without direct sunlight.

Working principle:

Clear water turbidity sensor (0~4000NTU):

Turbidity is caused by the suspended particles in water, which will reflect the incident light diffusely. Usually, the scattered light in the direction of 90 degrees is used as the test signal. In this way, the unit tested is called NTU. After several experimental studies and theoretical calculations, it is found that the ratio of scattered light to transmitted light is in line with turbidity. In the sensor, the ratio of scattered light to transmitted light is used instead of simply scattered light to measure turbidity. The accuracy and reliability of the sensor are improved, the maintenance is simpler, and anti-pollution property is enhanced.

Sewage turbidity sensor (0~10000NTU / 0~20000mg/l):

The concentration of suspended matter particles in sewage is very high. If traditional 90-degree scattering measurement is adopted, it is difficult to obtain accurate measurement results because suspended particles block a large amount of incident and scattered light. Therefore, we use 30-degree scattered light for measurement. The sensor's optical surface is coated with a unique nano antifouling coating that ensures the sensor doesn't require maintenance for two months.

Application:

Water's Turbidity Sensor is a highly accurate submersible instrument for in-situ environmental or process monitoring. Applications for the turbidity sensors include: water quality testing and management, river monitoring, stream measurement, reservoir water quality testing, ground water testing, water and wastewater treatment, and effluent and industrial control.
