The gas detector needs to be calibrated regularly.
For the accuracy and safety of use, we need to calibrate the gas detector regularly. The core component of the gas detector is the sensor. The service life of the sensor is counting down from the first day it is produced. Even if you don't use the gas detector, you need to do calibration inspection or replace the sensor in three months or six months or a year. In addition, all gas detectors adopt the method of relative measurement, so they all need to be maintained and corrected in time. Only by correcting at any time according to the manufacturer's requirements can we get the expected accurate results. This kind of calibration can be done in the National Metrology Institute, and it can also be sent to the after-sales service department of the manufacturer in China. The reports issued by them are different, but they can make the instrument work normally.
In addition, in order to ensure the accuracy of the gas detector and prolong its service life, we should pay attention to the following problems when using the gas detector.
1. Use the portable gas detector reasonably, and always check whether there is any abnormality in the components. If there is any abnormality, timely repair or replace it with a new one to ensure its normal use.
2. The gas detector is flame-proof and explosion-proof equipment, and shall not be used beyond the prescribed scope.
What gases can a portable gas detector detect?
1. COmbustible gases: such as hydrogen (H2), carbon monoxide (co), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2) and propyne (c2h8).
2. Toxic and harmful gases: chlorine, ammonia, nitrogen oxides, phosgene, hydrogen fluoride, sulfur dioxide, sulfur trioxide, dimethyl sulfate, nitrogen, methane, ethane, ethylene, carbon monoxide, nitrobenzene vapor, hydrogen cyanide, hydrogen sulfide, etc.
