Gas concentration detector is a gas leak detection instrument tool, is mainly refers to a portable/handheld gas detector. Main use gas sensors to detect environment that exist in gas species, gas sensor is used to detect the composition and content of the gas sensor. It is generally believed that the definition of a gas sensor is based on detection of target classification, that is, those who used to detect gas composition and concentration of sensor is called gas sensor, whether it is to use physical methods, or with chemical methods. For example, detection of gas flow sensor is seen as a gas sensor, but it belong to important thermal conductivity type gas analyzer gas sensors, although they sometimes use broadly consistent detection principle.
