    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 a handheld CO2 detector in daily life?

    sisco carbon dioxide detector is of great use in life. In public places such as kindergartens, schools, office buildings, shopping malls, supermarkets, stations, hospitals, etc., the monitoring of carbon dioxide concentration can improve air quality and ensure public safety and health.

    Versatile, user-friendly carbon dioxide monitor
    The handheld CO2 infrared gas detector is a versatile tool for anyone concerned about air quality. I appreciate its flexibility as it has an adjustable range from 0 to 2000/5000/10000 ppm. the device is simple to use and the infrared technology ensures accurate measurements. My only concern is the battery life, which could be extended during extended field use.

    Great carbon dioxide detector
    I am exposed to CO2 gas a lot and this portable gas detector is now my go-to safety tool. It is reliable and accurate, with warnings if concentrations are exceeded.
