                      丙烯腈氣體檢測管184S ALLYL ALCOHOL (+) CH2=CHCN 0.1-3.5%

                      簡要描述:

                      丙烯腈氣體檢測管184S ALLYL ALCOHOL (+) CH2=CHCN 0.1-3.5%,氣體檢測管是用來檢測某種氣體在某一環(huán)境中所含濃度的簡易檢測裝置,通過檢測劑與被檢測氣體的反應(yīng)而出現(xiàn)顏色變化,來表示所測環(huán)境中的氣體濃度。在不用任何能源、電源的情況下,具有操作簡單、使用范圍廣、檢測準(zhǔn)確、即時性強(qiáng)和經(jīng)濟(jì)的特點。
