How to select a Gas Detector

Gas detectors a widely used in petrochemical, environmental protection, gasoline, coal mining, and other industries. For all kinds of different safety production events and testing requirements, the choice of a suitable Gas Detector needs to be very essential for every person engaged in safety and health work.

Confirming the type and concentrated range of the gas to be tested

The type of gas encountered in every production department is distinctive. All possible conditions should be considered when choosing a gas detector.

For example, in the mining surroundings of coal mines, methane, and much less toxic alkanes, it is surely the most suitable choice for the selection of combustible gas detectors. This is not only because the detection principle of the gas detector is simple, the application is huge, but also it has the characteristics of convenient maintenance and calibration.

If there exists a toxic gas inclusive of carbon monoxide, hydrogen sulfide, ammonia, oxygen, hydrogen, phosphine, and different gases, it is desired to pick a single gas detector that concurrently detects CO, H2S, NH3, O2, etc., to make certain worker safety.

If there are more organic toxic and harmful gases, considering the lower concentration of human poisonings, consisting of fragrant hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, fat, and many others., PID photo ionization detector must be selected, and never use an LEL gas detector to cope with, which may additionally lead to casualties.

If the gas type covers the above types of gases, selecting a multi-gas detector may achieve twice the result with half the effort.
