气体检测器是检测毒气、可燃气和氧气含量的仪器,分固定式和便携式两种。以往,人们对便携式气体检测器的要求,仅限于在有毒有害气体的浓度构成之前报警;而且传统的便携式检测器只能检测一种气体或固定2～3种气体。尽管设计入员根据工业生产中最常见的几种气体制成了二合一或三 Gas detector is to detect gas, gas and oxygen content of the instrument, sub-fixed and portable two. In the past, portable gas detectors were only required to alarm prior to the formation of toxic and harmful gas concentrations. Moreover, conventional portable detectors can only detect one gas or two to three gases. Although designers are based on several of the most common gases in industrial production made of combo or triple
