Which four gases can the four-in-one gas detector detect?

The gases that can be detected are generally CO, H2S, LEL, and O2. They are generally used in closed and semi-closed spaces, as well as post-fire safety inspections at the scene of a fire. There are many fields of application, including petroleum, chemical industry, metallurgy, mining, fire protection, gas, environmental protection, electricity, communications, papermaking, printing and dyeing, grain reserves, urban water supply, sewage treatment, food, scientific research, education, and national defense. The application is relatively wide. Portable detectors are mainly used for inlet and outlet detection or safety inspections. It also depends on the usage to see whether to use the pump suction type or the diffusion type. The pump suction type is mainly used in confined spaces such as hot work inspections.

Four-in-one gas detector HNAG900-4-S is a composite gas detection alarm with superior performance. It can detect combustible gas, oxygen, carbon monoxide, hydrogen sulfide or other gases at the same time. It is suitable for safety detection before entering various industrial hazardous environments and confined spaces. The detector has a large LCD backlight display, sound, two-color light alarm and vibration prompt, ensuring that dangerous gases can be detected even in very unfavorable working environments and prompt operators to take precautions in a timely manner.
