The choice of gas detector becomes very important. When choosing, choose suitable testing equipment according to the specific situation.
1. Pay attention to the service life of the instrument
Different gas detectors have different service life. When purchasing, ask about the service life of the instrument and use it within the warranty period. In order to save costs, individual companies use a detector for several years without replacing it. Once a gas leak occurs Prone to safety accidents.
2. Pay attention to the interference of different gases
When we detect gas leakage, we usually use a single gas detector to detect a specific gas, but there is often more than one gas in the detection environment, so we should pay attention to whether other gases will interfere with the detection of the instrument and make the detection results Inaccurate.
3. Pay attention to the measure range
Before testing, in addition to estimating the types of toxic and harmful gases based on experience in advance, it is also necessary to roughly estimate the gas concentration, and set the alarm value through the gas detector for detection. When the gas concentration exceeds the detection range of the instrument, turn off the detector. If the gas detector is in an over-range detection state for a long time, it will cause serious damage to the instrument, which will cause its detection to be inaccurate or directly scrapped.
4. Pay attention to the maintenance of the instrument
The gas detector is the same as other equipment. It is also necessary to pay attention to regular maintenance. It should be calibrated and tested from time to time, and stored in a lower temperature environment to extend its service life.
