固定式六合一气体检测仪标识的PID是什么意思-金沙集团186cc(中国)有限公司官网

固定式六合一气体检测仪标识的PID是什么意思呢?实则PID指的是一种传感器原理，目前PID传感器主要是用途于检测有机化合物挥发性TVOC气体浓度的，不过小伙伴要注意，固定式六合一气体检测仪对于测TVOC气体的，检测原理上区分有PID和FID，很多用户经常都会把这两者搞混，PID又别称为PID光离子，而FID，别称为FID火焰离子，那他们在检测原理上有什么不一样呢?一般气体检测仪PID原理是采用一个紫外灯来离子化样品气体，从而检测其浓度。而FID原理是采用氢火焰的办法将样品气体进行电离，这些电离的离子可以很容易的被电极检测到其浓度。
