19.5%～21%，在富氧環(huán)境下不得大于23.5%。硫化氫作業(yè)：當(dāng)硫化氫濃度低于40ppm時可以佩戴過濾式防毒面具作業(yè)，并在濾毒罐表面注明適用物質(zhì)；　　當(dāng)硫化氫濃度大于40ppm或濃度不明或二氧化硫濃度高于2ppm的區(qū)域內(nèi)作業(yè)時應(yīng)使用正壓式空氣呼吸器；　　嚴禁任何人不佩戴合適的防護用品進入可能含有硫化氫氣體的區(qū)域，禁止在有危險區(qū)域內(nèi)摘除防毒用具。

style="text-indent:25px">在氣體檢測儀上我們經(jīng)常看到上面標(biāo)注的有“PPM”、“LEL”，那么什么是“PPM”、“LEL”呢，也許很多人都不是太清楚，現(xiàn)在我們來詳細介紹這兩個詞的具體含義。 “PPM”是體積比濃度?！癙PM”是溶液濃度的一種表示方法， PPM 表示百萬分之一。對于溶液：即1升水溶液中有1/1000毫升的溶質(zhì)，則其濃度為1 PPM 。對于氣體：對環(huán)境大氣中污染物濃度的表示方法之一。體積濃度表示法：一百萬體積的空氣中所含污染物的體積數(shù)，即PPM ，大部分氣體檢測儀器測得的氣體濃度都是體積濃度（ PPM ），而按我國規(guī)定，特別是環(huán)保部門，則要求氣體濃度以質(zhì)量濃度的單位表示，我們國家的標(biāo)準(zhǔn)規(guī)范也都是采用質(zhì)量濃度單位表示。它是利用一些金屬氧化物半導(dǎo)體材料，在一定溫度下，電導(dǎo)率隨著環(huán)境氣體成份的變化而變化的原理制造的。自貢氣體檢測儀器哪家好</p><p style="text-indent:25px">巴中氣體檢測儀器價格</p><p style="text-indent:25px">氣體檢測儀器是一種氣體泄露濃度檢測的儀器儀表工具，主要是指便攜式/手持式氣體檢測儀器。主要利用氣體傳感器來檢測環(huán)境中存在的氣體種類，氣體傳感器是用來檢測氣體的成份和含量的傳感器。一般認為，氣體傳感器的定義是以檢測目標(biāo)為分類基礎(chǔ)的首先步是將氣體探測器安裝在可能有氣體泄漏的區(qū)域中，氣體探測器安裝必須牢固，且安裝位置根據(jù)被測氣體相對于空氣比重大小決定，因被測氣體比重小于空氣，探測器應(yīng)安裝在距頂棚30～60cm處。用Φ8膨脹螺絲將探測器固定在墻壁上。巴中氣體檢測儀器價格</p><p
