portable infrared (IR) gas detector A portable infrared (IR) gas detector is a compact, handheld device designed to detect the presence of specific gases in the surrounding environment.A variety of gases, including hydrocarbons, carbon dioxide, methane, and others. operate on the principle of infrared absorption. Certain gases absorb infrared light at specific wavelengths, and the amount of absorption is directly proportional to the gas concentration in the sample.Detection Resolution-0.1ppm;Sampling mode-Pumping type;Response time-1 to 5s;Operation temperature-10 to 60℃ for more visit labtron.us
