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: How does a hydrogen peroxide detector work?
The portable hydrogen peroxide(H2O2) gas detector is based on the electrochemical principle. It is a gas sensor based on the detection electrode of the oxidation reaction, the counter electrode of the reduction reaction at the same time, and the reference electrode used to monitor and balance the continuous voltage. The hydrogen peroxide sensor relies on the oxidation reaction between the electrolyte and the detected gas. The higher the concentration of the detected gas, the stronger the response and the greater the signal. The level of gas concentration is measured by the magnitude of the semaphore.
