    Q1: What is a gas detector?
     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: What does a gas detector detect?
    A2: 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: What is ppm of gas detector?
    A3: 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 is phosphine (PH3)?

    Phosphine is an inorganic compound with the chemical formula PH3. It is a colorless, highly toxic, flammable liquefied compressed gas stored in cylinders. Pure phosphine gas is colorless and odorless, but when metal phosphide produces phosphine gas, it often has an odor. If encountered in trace amounts of other phosphorus hydrides such as ethyl phosphine, it will cause spontaneous combustion. Inhalation of phosphine can affect the human heart, respiratory system, kidneys, gastrointestinal tract, nervous system and liver, so a phosphine gas detector is necessary.
