Applications： 

Turbidity monitoring of water from waterworks, water quality

monitoring of municipal pipeline network; industrial process

water quality monitoring, circulating cooling water, activated

carbon filter effluent, membrane filtration effluent, etc

Feature：

1.This product is a circulating turbidity digital sensor, which can directly output RS485 signal.

2.The internal structure can effectively eliminate water bubbles and improve the measurement accuracy and stability.

3.When the outlet joint module is disassembled, the optical path lens and the inner wall of the flow groove can be

cleaned, and the maintenance is more convenient.

4.The internal upgrade of the sensor can effectively prevent the internal circuit from dampness and dust accumulation,

and avoid damage to the internal circuit.

5.The transmitted light adopts stable invisible near-monochromatic infrared light source, which avoids the interference

of chroma in liquid and external visible light to sensor measurement.And built-in luminosity compensation,

improve the measurement accuracy.

6.The use of quartz glass lens with high light transmittance in the optical path makes the transmission and reception

of infrared light waves more stable.

7.Wide range, stable measurement, high precision, good reproducibility.

8.Without meter, the sensor can be set online through software, from the machine address and baud rate, online

calibration, restore factory, RS485 output corresponding range, modify the range, proportional coefficient and

incremental compensation Settings.
