Some of the gases are necessary and non-hazard for human survival, but some of the gases are toxic and dangerous, and therefore need to use gas detectors for these hazardous gases and in the unit space. The concentration is effectively detected. However, since the occasion of use and the type of gas are not likely to be different, it is necessary to select a suitable gas detector to use.

Gas type

When selecting a combustible gas detector, various possibilities are taken into consideration. If the gas to be detected is methane and a less toxic alkane gas, then a detector such as LEL can be selected for testing. However, when hydrogen sulfide or a toxic gas such as carbon monoxide is required to be tested, it is necessary to select a specific gas detector to ensure the safety of the operator. If the organic gas is to be detected, since the gas may cause a poisoning reaction of the operator at a low concentration, a composite multifunctional gas detector is selected.

2. The degree of closure of the occasion

The gas detectors that need to be selected for different occasions are different. For example, in a more open space, technicians can use a portable gas detector that can be carried, because the detector can display continuously. The gas concentration in the on-site environment, the monitored gas data is not only highly accurate but also real-time. However, if gas detection is required for a closed chamber such as a reaction tank, it is necessary to select a multi-gas detector with a built-in sampling pump.

It can be seen that the safe and accurate detection of various gases cannot be too casual when selecting a gas detector. The correct selection method is based on the type of gas to be detected and the concentration range, and the degree of openness of the inspection site. The choice, in order to be prepared, allows the operator to use the gas detector for safe detection.
