The principle of instrument detection mainly includes catalytic combustion, infrared absorption, and thermal conductivity types. The sampling methods are diffusion and aspiration. The instrument is mainly composed of detection elements, amplifying circuits, alarm systems, and displays, used for monitoring the concentration of combustible gases in the environment.
