Toxic gas detector is an instrumentation tool for detecting the concentration of toxic gas leaks, mainly referring to portable or handheld gas detectors. Toxic gas sensors are mainly used to detect gas species present in the environment. Unlike the combustible gas detector, the toxic gas detector can be used universally. For example, carbon monoxide detector and CL2 gas detector are both called toxic gas detectors, but because the specific gases they measure are different, these two are completely different toxic gas detectors.
