What is the explosion-proof type of 1. gas detector?

The gas detector depends on whether it has reached the explosion-proof level, the general explosion-proof grades of the detector are BT3, BT4 and CT3, so we can look at these explosion-proof grades when purchasing and testing.

What gases do 2. gas detectors routinely detect?

Gas detectors can detect hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone and combustible gases.

3. gas detector what is the reverse measurement of nitrogen with oxygen

oxygen and nitrogen are relatively common gases. the main components in air are 30% oxygen and 70% nitrogen. due to the relatively high price of nitrogen special sensors, some people will choose to use the oxygen sensor to counter-measure nitrogen, in fact, it is possible, that is, to use 100 minus the oxygen content value, that is, the oxygen content value.

4. the difference between natural diffusion type and pumping type of gas detector

Gas detectors all know that there are two most common detection methods, the 1 is natural diffusion type and the 1 is pumping type, but I don't know what is the difference between the two. The natural diffusion type is to slowly sense the gas without applying any external force. The pump suction type is to use a self-priming pump to inhale spontaneously. For example, the human nose reacts faster, so when choosing What detection method should be identified to effectively detect the gas.

which gases are contained in the standard four-in-one gas detector for 5.

some people are not very clear about the standard four-in-one gas and some detection range of the commonly mentioned gas, simply say the standard four-in-one gas: flammable (methane) 0-100% LEL, carbon monoxide 0-1000PPM, oxygen 0-30% VOL, hydrogen sulfide 0-100PPM.

6. gas detector application range;

is widely used in petrochemical, coal, metallurgy, chemical industry, municipal gas, environmental monitoring and other places on-site detection. It can realize the measurement needs of special occasions; it can detect the gas concentration or leak detection of tunnels, pipelines, tanks, confined spaces, etc.
