Q1: What is a gas detector?
A1: 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: Fixed vs. Portable Nitric Oxide (NO) Detector
The fixed nitric oxide detector is mainly used to detect the concentration of nitric oxide in the air. It is fixed in one position and used 24 hours a day, with real-time monitoring and real-time transmission, which can effectively avoid the harm caused by high nitric oxide concentration to the human body.
Handheld nitric oxide detectors are mainly used in confined space operations. When operators enter a nitric oxide site, they must carry a portable nitric oxide detector to avoid nitric oxide poisoning accidents.
