The gas detector is a very precise monitoring instrument with limitations. It is crucial to keep the gas detector clean. During daily use, the detector needs to be anti-fouling, dust-proof and waterproof. Particular attention must be paid to not being contaminated by organic silicon compounds, acidic compounds, lead-containing compounds, etc., to avoid damaging the detector. Therefore, when there are polluting gases or dust in the surrounding environment of the gas detector, the gas detector needs to be cleaned regularly.

Operators need to understand the corresponding relationship and installation location of gas detectors and alarm controllers. At the same time, on-site personnel need to regularly check whether the controller is powered on so that it can truly function. The alarm also needs to be protected from rain to prevent the alarm from being wetted by rain, and to prevent the alarm from being affected by moisture, affecting the performance of the gas detector itself, or even causing damage to the detector. In this regard, staff need to regularly check whether the rainproof facilities of the alarm are intact, and replace or repair them in time if they are found to be damaged or have other problems.

In addition, gas detectors may experience reduced sensitivity or inaccurate measurement results after long-term use. It is necessary to regularly check whether the gas detector is within its service life. Gas detectors should not be in direct contact with high-concentration gases. This is because high-concentration combustible gases will generate a large amount of reaction heat once burned, which will reduce the sensitivity of the detector to a certain extent. Under the action of reaction heat, the detector in the detector The measuring bridge faces the possibility of being damaged. If the concentration of combustible gas in the surrounding environment is high and the concentration of oxygen in the air is low, the combustible gas may not be completely burned and the carbon black produced by combustion will be deposited on the surface of the detector, eventually causing the alarm to malfunction.
