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 VOC gas detector detect?
- The VOC gas detector can detect VOCs components with strong odors (such as methyl mercaptan, methyl sulfide, and dimethyl disulfide). The escape of these components into the air will cause intense discomfort to people.
- The portable VOC detector can detect VOCs components related to ozone and haze. This type of VOCs components can generate ozone and PM2.5 in photochemical reactions with nitrogen oxides, which directly cause environmental pollution and lead to poor air quality.
- The VOCs gases that are toxic and harmful to human health mainly refer to the VOCs components that can cause the formation of cancer (such as benzene series such as stupid and xylene) and are toxic to the human body (such as vinyl chloride).
