    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: Why use hydrogen cyanide detectors in factories?

    Hydrogen cyanide (HCN) is a colorless and transparent liquid under normal temperature and pressure. It is easy to disperse evenly in the air and can be incinerated. When the content of hydrogen cyanide in the air reaches 5.6% to 12.8%, it is explosive. Therefore, the factory must install a sisco hydrogen cyanide detector to prevent damage caused by the leakage of toxic gas.
