丁基甲基酮氣體檢測管237S Methyl butyl ketone 5-80ppm

簡(jiǎn)要描述:

丁基甲基酮氣體檢測管237S Methyl butyl ketone 5-80ppm 醋酸乙烯酯CH3(CH2)3COCH3氣體檢測管237S VINYL ACETATE 在煤礦和石油化工行業(yè),大多存在可燃性易爆氣體、有毒氣體及窒息性氣體,使
用檢測管可以快速準確地檢測空氣中有毒有害氣體。檢測管廣泛用于生產(chǎn)設備動(dòng)火前和進(jìn)入密閉設備前的安全分析;用于檢查生產(chǎn)設備管道泄漏情況;用于大氣、水質(zhì)等環(huán)境監測和工業(yè)設備廢水污染監測;用于各種地質(zhì)勘探和礦山開(kāi)采中地下溢出的氣體和污染分析;也可在汽車(chē)尾氣排放
