one. Online cod turbidity sensor working principle

Online cod turbidity sensor requires no reagents and is pollution-free. It can measure cod and turbidity of water quality online for a long time.The sensor uses two light sources for measurement, one for COD measurement and one for turbidity measurement.

Because organic matter dissolved in water absorbs ultraviolet light, the COD value can be measured through the transmittance of the light source, along with turbidity measurement, automatic turbidity compensation, and temperature collection for temperature compensation.

Note: The sensor cannot be installed upside down and must be installed at an angle of at least 15 degrees.

Four. Online cod turbidity sensor maintenance and care

Sensor maintenance:

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

Notice:

Avoid strong vibrations that may damage the transparent glass in front of the ring, and do not scratch it with hard objects.

five. Online cod turbidity sensor user calibration

The sensor has been rigorously calibrated when it leaves the factory, and generally does not require user calibration. If user calibration is performed, you can execute the factory reset command if you want to restore it.

5.1 Zero point calibration

Integrate the sensor into the container. Use distilled or purified water for the solution. After the value stabilizes for 30 seconds, perform turbidity zero point calibration and COD zero point calibration according to the communication instructions.

5.2 Slope calibration

Integrate the sensor into the solution container. The turbidity value of the solution is known. After the value stabilizes for 30 seconds, perform turbidity slope calibration according to the communication instructions.

Integrate the sensor into the solution container. The COD value of the solution is known. After the value stabilizes for 30 seconds, perform COD slope calibration according to the communication instructions.
