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: What is a combustible gas detector?
A combustible gas detector is a device designed to detect the presence of flammable gases in an area. Its main purpose is to alert users to potentially dangerous levels of gas before it reaches a concentration that could ignite or explode. These detectors work by continuously monitoring the air and triggering an alarm when they detect gases such as methane, propane, butane, or hydrogen.
Combustible gas detectors are commonly used in industries like oil and gas, chemical manufacturing, and in households where natural gas or propane is used. They help ensure safety by providing early warnings, allowing for immediate action to prevent accidents.
