How to do the daily maintenance of the gas detector
1. Regularly check the gas flow rate. The general gas flow rate is 30/h. When the flow rate through the instrument is too large or too small, the measurement results of the gas detector will be greatly affected.
2. After a period of use, the filter paper should be replaced regularly: when replacing the filter paper, the air pump should be stopped and the filter tank should be emptied.
3. Check whether there is any air leakage in the air system during use. Whether the diaphragm of the suction pump in the instrument is damaged, whether the sealing ring of the sampling probe is damaged, whether the four-way valve, condensate and other components are damaged, etc., regular inspection and maintenance are very necessary.
4. Regularly clean the sampling probe and dredge the sampling hole pipeline.
5. During the use of the gas detector, attention should be paid to check whether the working state of the condenser is normal. Usually, the operating temperature of the instrument is adjusted within 3 degrees Celsius.
6. It is necessary to regularly check whether there are impurities in the metering room, and it needs to be cleaned in time.
