目前可燃气体探测器大多数采用的是催化燃烧原理。
At present, most of the flammable gas detectors are based on the catalytic combustion principle.
当被测气体的环境氧气含量较低，或者含有易使催化元件中毒的某些背景气体时，催化燃烧原理探测器的使用就受到了一定的限制。
When the detectors are used to measure the gas of low oxygen environment, or certain background gas which can easily poisoned the catalyze components, they have certain limits.
