Gas Detector Software
Q1:Â What is a gas detector?
A1:Â A gas detector is an instrument for gas leakage concentration detection, including a portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc.
Q2:Â What does a gas detector detect?
A2:Â Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3:Â What is ppm of gas detector?
A3:Â Parts per million or "ppm" is often used as a fractional measure of concentration. For example, a methane (molecular) concentration of 2% means that 2 out of every 100 air molecules are methane. Likewise, a methane concentration of 2 ppm means that 2 out of every 1 million air molecules are methane.
Tips for maintaining a portable explosion-proof gas detector
- Check the gas flow rate, usually 30/h. Excessive or too small flow will have a greater impact on the portable gas detector results.
- Replace the filter paper of gas detector: stop the air pump and drain the filter tank.
- Check whether there is any air leakage in the gas system. Whether the diaphragm of the sobbing pump is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and condensate are damaged, etc.
- Cleaning the sampling probe of gas detector and dredging the sampling hole pipeline
- Check whether the condenser is working normally, usually, the temperature is adjusted within 3℃.
- Check the measuring device room to see if it is dirty, and clean it in time.
