Water Turbidity Sensor DST420


Water Quality Testing Device 1000NTU

Product Description

High-precision Turbidity Meter Air Formaldehyde Tester Water Formaldehyde Tester Water Quality Testing Device 

Product Description


Our turbidity sensors use fiber optic technology to provide superior repeatability and stability, and are less susceptible to ambient light. The automatic cleaning brush with the sensor can effectively eliminate air bubbles and reduce the influence of contamination on the measurement. It has a longer maintenance period and maintains excellent stability for long-term online use.


Before installation, please check the appearance of the cables for damage, and disperse the cables.

1. When using the throw-in sensor, avoid the sensor hitting the wall or other facilities caused by water flow. If the water flow rate is too fast, the sensor must be fixed.

2. There should be no obstructions in front of the measurement. For example, fluorescence sensors should be avoided from light.

3. The water depth position where the sensor is installed should not exceed 2 meters from the horizontal, and the installation should be based on the fluctuation of the water flow. The water depth of the location should not be less than 30 cm. (Adjustable according to the measured water body)

4. The sensor should be installed in a location where there is no air bubbles to prevent air bubbles from affecting the measurement data of the sensor.

5. Do not use the sensor's own cable to hoist the sensor, and install a cable protection device to prevent excessive tension between the cable and the sensor, causing the cable to break.

6. The sensor should not be installed with the measuring side facing upwards, it can be installed vertically downwards or horizontally.

7. If you use this product in the water diversion tank, please consult the company's sales staff to confirm the specific installation requirements.
