Hydrogen is the smallest known gas in the world, with a density of only 1 / 14 of that of air, that is, at 0°C and a standard atmospheric pressure, the density of hydrogen is 0.0899 g / L. Hydrogen is the substance with the smallest relative molecular mass and is mainly used as a reducing agent. A gas detector is an instrument tool for detecting gas leakage concentration, including: portable gas detectors, handheld gas detectors, fixed gas detectors, online gas detectors, etc.
