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 for Installing Hydrogen Sulfide(H2S) Detector
- The density of hydrogen sulfide gas is heavier than air, and the installation height of the hydrogen sulfide detection probe should be 0.3-0.6m away from the floor (or floor).
- The hydrogen sulfide detection probe should be installed in a place without impact, vibration and strong electromagnetic field interference, and a space of not less than 0.3m should be left around.
- The installation and wiring of the hydrogen sulfide detector shall be carried out in accordance with the requirements specified by the H2S detector manufacturer and shall comply with the relevant regulations on the installation and wiring of explosion-proof instruments.
