style="text-indent:25px">如今大家是否了解我們?nèi)粘Ｉ钪惺褂玫乃暮弦粴怏w檢測(cè)儀該怎樣確定安裝高度嗎？相信大家都不是那么的了解，那沒(méi)下面就請(qǐng)跟隨四合一氣體檢測(cè)儀小編去了解吧。(1)四合一氣體檢測(cè)儀安裝距地面及墻壁不易太近，且周圍留下不小于0.3m的凈空。便于標(biāo)定時(shí)安裝氣罩。另外，墻表面易吸收毒性氣體，并隨著溫度、濕度的變化向外釋放，影響傳感器的正常工作。(2)四合一氣體檢測(cè)儀的有效覆蓋水平平面半徑，室內(nèi)宜為7.5m;室外宜為15m。(3)室外安裝應(yīng)考慮風(fēng)雨情況，安裝防雨罩及防曬板(安裝支架帶有防曬板)。(4)安裝高度應(yīng)根據(jù)被測(cè)氣體的密度來(lái)確定，對(duì)于密度大于空氣的氣體將其安裝高度應(yīng)距地坪(或樓地板)0.3～0.6m。若該區(qū)域經(jīng)常用水沖洗或經(jīng)常下雪，應(yīng)將探測(cè)器安裝的高些，以保證傳感器不被浸濕或被積雪掩埋。</p><p style="text-indent:25px">氣體檢測(cè)儀怎么分類的：按使用方法分類：1、便攜式有害氣體檢測(cè)儀儀器將傳感器、測(cè)量電路、顯示器、報(bào)警器、充電電池、抽氣泵等組裝在一個(gè)殼體內(nèi)，成為一體式儀器，小巧輕便，便于攜帶，泵吸式采樣，可隨時(shí)隨地進(jìn)行檢測(cè)。袖珍式儀器是便攜式儀器的一種，一般無(wú)抽氣泵擴(kuò)散式采樣，干電池供電，體積極小。2、固定式有害氣體檢測(cè)儀。這類儀器固定在現(xiàn)場(chǎng)，連續(xù)自動(dòng)檢測(cè)相應(yīng)有害氣體(蒸氣)，有害氣體超限自動(dòng)報(bào)警，有的還可自動(dòng)控制排風(fēng)機(jī)等。固定式儀器分為一體式和分體式兩種。一體式固定有害氣體檢測(cè)儀：與便攜式儀器一樣，不同的是安裝在現(xiàn)場(chǎng)，220V交流供電，連續(xù)自動(dòng)檢測(cè)報(bào)警，多為擴(kuò)散式采樣。分體式固定有害氣體檢測(cè)儀：傳感器和信號(hào)變送電路組裝在一個(gè)防爆殼體內(nèi)，俗稱探頭，安裝在現(xiàn)場(chǎng)(危險(xiǎn)場(chǎng)所)；包括數(shù)據(jù)處理、二次顯示、報(bào)警控制和電源，組裝成控制器，俗稱二次儀表，安裝在控制室。探頭擴(kuò)散式采樣檢測(cè)，二次儀表顯示報(bào)警。按可檢測(cè)的氣體數(shù)量可分為單一氣體檢測(cè)儀和多種氣體檢測(cè)儀。</p><div
