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: Nitrogen Detector in Smelting Industry
Nitrogen is mainly used in the smelting industry. Filling the non-ferrous metal smelting furnace with nitrogen can reduce the amount of oxygen and temperature, reduce oxidation and improve product purity. The molten steel is purged with nitrogen to reduce the hydrogen content in the steel and improve the strength of the product. Therefore, a fixed nitrogen gas detector needs to be installed in the pipeline for nitrogen transmission to detect nitrogen leakage. Some pipelines may leak nitrogen due to aging and loose connection parts. Installing a nitrogen detector can timely obtain leak information reminders, deal with leak points in time, and avoid major leak accidents. Usually, operators also need to carry portable nitrogen monitors with them.
