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: What gases does the NOx gas detector measure?
A portable NOx gas detector is specifically designed to measure nitrogen oxides, primarily nitrogen monoxide (NO) and nitrogen dioxide (NOâ‚‚). These two gases are the major constituents of NOx emissions, commonly produced by combustion processes such as those in vehicles, industrial facilities, and power plants. Depending on the detector model, the device may include separate sensors for NO and NOâ‚‚, allowing for individual readings as well as a calculated total NOx value. Some advanced detectors may also offer additional gas detection capabilities or data logging features for environmental monitoring and compliance testing. Always refer to the product specifications to confirm the exact gases measured and sensor ranges.
