Sulfur dioxide (SO2) is a common, simple and irritating sulfur oxide. Moderate intake of sulfur dioxide will not cause harm to the body, but once it is excessive, it will cause adverse effects on the body. At this time, we need to use a sulfur dioxide detector to detect whether the concentration of sulfur dioxide (SO2) in the air exceeds the standard, so as not to cause harm to the human body. However, no matter what kind of instrument product is used, it needs to be maintained in order to better complete the relevant testing work. So what are the maintenance specifications for Sulfur Dioxide Detector ? The following is a brief introduction by yi yun Tian:

Maintenance Specification for Sulfur Dioxide Detector:

1. Regularly check the sulfur dioxide detector, calibration and impact test.

2. Keep away from dust and keep the environment around the sulfur dioxide detector clean.

3. The ambient temperature is moderate and should not be too high or too low to avoid affecting electronic components.

4. It is forbidden to use harsh chemicals, detergents or cleaning agents in high concentration.

5. When maintaining the sulfur dioxide detector, be sure to pay attention to the detection interference between various sensors.

6. It is feasible to use a soft cotton cloth dipped in a small amount of water and wipe the instrument, and it needs to be dried in time.

7. Keep the surface of the sulfur dioxide detector dry and clean, away from moisture, rain and corrosive liquids.

8. For air leakage in the air circuit system, check whether the air pump diaphragm is damaged, check whether the sealing ring is damaged, and whether the condensed gas or the four-way valve is damaged.

9. the detection hole of the sulfur dioxide detector should be wiped frequently to keep the hole tube unblocked and prevent liquid from flowing into the detection hole. Once the liquid flows in, it will be placed down so that the liquid will automatically flow out.

10. Check whether there is air leakage in the sulfur dioxide detection gas circuit system. Whether the diaphragm of the sobbing pump is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and cold condensate are damaged, etc.

In summary, it is the maintenance specification for the sulfur dioxide detector.In addition to the above aspects, we also pay attention to the service life of various types of sensors, such as electrochemical specific gas sensor life is usually one to two years; like the life of the photoionization detector is four years or more; and the life of the LEL sensor can usually be used for about 3 years. The life of the oxygen sensor is about one year.
