An infrared gas detector is an advanced device that uses infrared light to detect gases in the air. The detector works by emitting infrared light through a gas sample; gases absorb specific wavelengths of light, and the detector measures this absorption to determine the type and concentration of the gas. Infrared detectors are highly accurate, reliable, and require minimal maintenance. They are commonly used in industries such as oil and gas, chemicals, and manufacturing for safety, ensuring early detection of hazardous gas leaks.
