Online cod turbidity sensor

one. How Online cod turbidity sensor works

Online cod turbidity sensor measures the turbidity of water and can easily monitor the turbidity level of drinking water treatment plants, wastewater treatment facilities, industrial water.The sensor uses two light sources for measurement, one COD measurement, and one turbidity measurement.

Because organic matter dissolved in water has an absorption effect on ultraviolet light, COD values can be measured through the transmittance of the light source, and turbidity measurement can be performed automatically, and temperature compensation can be performed at the same time.

3.Online cod turbidity sensor installation

Note: The sensor cannot be inverted when installed, and it must be installed at least 15 degrees of tilt.

Four. Online cod turbidity sensor maintenance and maintenance

Sensor maintenance:

If the sensor needs to be cleaned, you can use warm water and an appropriate amount of detergent to clean it.

Notice:

Avoid strong vibration damage to the front of the transparent glass, and do not scratch with hard products.

five. Online cod turbidity sensor user calibration

The sensor has been carefully calibrated when it leaves the factory, and generally does not require user calibration. If the user calibration is performed, you can execute the instructions to restore the factory.

5.1 Zero Point Calibration

Invade the sensor into the container, use distilled water or purified water for the solution. After the value is stabilized for 30 seconds, perform turbidity zero-point calibration and COD zero-point calibration according to the communication instructions.

5.2 Slope calibration

Invade the sensor into the solution container, and the turbidity value is known. After the value stabilizes for 30 seconds, the turbidity slope calibration is performed according to the communication instructions.
