氟氣HF氣體檢測管156S HYDROGEN FLUORIDE 0.17-30ppm

簡要描述:

氟氣HF氣體檢測管156S HYDROGEN FLUORIDE 0.17-30ppm,氟是一種鹵族化學(xué)元素,它的化學(xué)符號是F,它的原子序數(shù)是9。氟是一種腐蝕性的淡黃色雙原子氣體。氟是電負度Z強的元素,也是很強的氧化劑。在常溫下,它幾乎能和所有的元素化合,并產(chǎn)生大量的熱能, 氟是劇毒性氣體,能刺激眼、皮膚、呼吸道粘膜。由于它立即與水反應(yīng)生成氟化氫,所以在大多數(shù)情況下顯出與氟化氫同樣的毒性。

(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.
