FAQs
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 do the units PPM, %LEL, %VOL mean in the gas detector?
- PPM: PM refers to parts per million, a unit of gas volume concentration.
For solution: it means that there’s 1/1000 ml solute in the 1L aqueous solution, so its concentration is 1ppm.
For gas: it’s one of the representation methods of pollutant concentration in the ambient atmosphere (air).
- %LEL: LEL refers to the lower explosive limit. When the combustible gas reaches 100%LEL, it’s easy to explode, and the explosion occurs as soon as contacting an electric spark. Therefore, 0-100%LEL generally refers to the range of combustible gas measurement. For example, hydrogen: 4%VOL=100%LEL, methane: 5%VOL=100%LEL.
- %VOL: VOL refers to the volume ratio of target gas per volume. It’s generally used for high concentration. 1%VOL is equal to 10000PPM, and generally, it is for oxygen and combustible gases.
