如何知道PID能否测量某种气体

首先,看气体的IP是否比PID灯的输出能量低:

(1)LEL传感器检测的是爆炸性而非毒性。

LEL传感器测量的是爆炸下限的百分比,例如,汽油的爆炸下限是1.4%,因而, 100% LEL 就是14,000 ppm 的汽油。10% LEL 是1,400 ppm的汽油,1% LEL是140 ppm的汽油。140 ppm是LEL传感器可以检测到的最小的汽油蒸气量。汽油的TWA值(时间加权平均值)是300 ppm 而其STEL(短期暴露水平)是500 ppm,这些,再加上LEL传感器的较差的分辨率都说明LEL不适合于检测汽油泄露。LEL欢乐生肖传感器测量的是爆炸性而不是毒性。实际上,很多VOC(有机化合物)即使在其浓度远远低于LEL传感器灵敏度时就已经具有了很大的毒性。

(2)LEL 传感器是专用于测量甲烷气体的
