氟气HF气体检测管156S HYDROGEN FLUORIDE 0.17-30ppm

简要描述:

氟气HF气体检测管156S HYDROGEN FLUORIDE 0.17-30ppm,氟是一种卤族化学元素,它的化学符号是F,它的原子序数是9。氟是一种腐蚀性的淡黄色双原子气体。氟是电负度Z强的元素,也是很强的氧化剂。在常温下,它几乎能和所有的元素化合,并产生大量的热能, 氟是剧毒性气体,能刺激眼、皮肤、呼吸道粘膜。由于它立即与水反应生成氟化氢,所以在大多数情况下显出与氟化氢同样的毒性。

(NOTE)
1)This detector tube is affected by ambient temperature and humidity,therefore, it is necessary to compensate
the reading of gas detector tube with the following equation and correction coefficient table.
Actual concentration=Reading Value×Correction Coefficient
2)In case of 6 pump strokes, following formula is available for the actual concentration.
