Frequently Asked Questions
Q1: What is a gas detector?
A1: A gas detector is an instrument for gas leakage concentration detection, including portable gas detectors and fixed gas detectors.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas, acetylene, pentane, alkynes, toluene, etc. Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: What is the ppm unit of the gas detector?
A3: ppm represents the volume concentration of the gas, meaning the volume of pollutants contained in one million volumes of air. For example, if the concentration of ammonia is 30ppm, it means that the volume of ammonia in one million volumes of air is 30.
