Four major issues that should be paid attention to when choosing a gas detector
With the development of the economy and the improvement of people's living standards, people are paying more and more attention to health and safety issues. In addition to paying attention to the safety of daily life, food, housing, and transportation, the hazards of gases are gradually being taken seriously, especially industrial toxic and harmful gases. Therefore, many enterprises have taken many protective measures to protect against toxic gases. For example, employees working in toxic gas environments need to wear corresponding gas masks and protective clothing, install fixed gas detectors at equipment interfaces and valves, and use portable gas detectors to regularly detect and record the concentration of harmful gases in specific areas. The selection of gas detectors should be based on specific situations, and suitable detection equipment should be selected. When using them, four major issues should also be noted:
1. Attention should be paid to the different service lives of gas detectors. When purchasing, it is important to inquire about the service life of the instrument and use it within its warranty period. Some companies, in order to save costs, use a detector for several years without replacing it, and gas detection is only for show, which can ultimately harm others and oneself.
2. We should pay attention to the interference of gas on instrument detection. When detecting gas leaks, we usually use a single gas detector to detect a specific gas, but there is often more than just one gas in the detection environment. Therefore, we need to pay attention to whether other gases will interfere with the instrument's detection and make the detection results inaccurate.
3. Attention should be paid to the concentration range detected by the gas detector. Before detection, in addition to estimating the types of toxic and harmful gases based on experience, it is also necessary to roughly estimate the gas concentration. The gas detector should be set with an alarm value for detection. When the gas concentration exceeds the detection range of the instrument, the detector should be turned off. Prolonged detection of the gas detector in an over range state can cause serious damage to the instrument, leading to inaccurate detection or direct scrapping.
4. Attention should be paid to the maintenance of the instrument. Like other equipment, gas detectors should also be regularly maintained, calibrated and tested irregularly, and stored in a lower temperature environment to extend their service life.
