一、氫氣氣體檢測儀CQH100礦用帶煤安證防爆證簡 介
氫氣是井下*輕的有害氣體。空氣中氫氣濃度達(dá)到4%~74%時(shí)具有爆炸危險(xiǎn)。井下氫氣的主要來源是變壓器和蓄電池充電。此外，礦井發(fā)生火災(zāi)和爆炸事故中也會(huì)產(chǎn)生。
CQH100用于礦井中氫氣的檢測，如用在變壓器、井下變電站、機(jī)房、可用于礦井火災(zāi)中標(biāo)志氣體的檢測與分析，也可以發(fā)生爆炸后的救援場合，它采用進(jìn)口的電化學(xué)傳感器，反應(yīng)靈敏，準(zhǔn)確可靠。 儀器采用堅(jiān)固的工程塑料外殼和良好的保護(hù)設(shè)計(jì)，能使用在諸如具有瓦斯粉塵的爆炸性環(huán)境中。儀器小巧輕便，能很容易的夾住皮帶，襯衫口袋或**帽上。超大高亮度OLCD液晶在黑暗的井下依然清晰可見，可讀出氣體濃度、時(shí)間、電量等數(shù)據(jù)。如果當(dāng)前氣體濃度值超出預(yù)設(shè)限度值時(shí)，儀器以聲、光報(bào)警提醒用戶。
試用場所：適于有瓦斯爆炸和煤與瓦斯突出危險(xiǎn)的場合，包括井下變壓器、供電站、變電站、礦山救護(hù)、煤礦采掘工作面、回風(fēng)巷道等使用。

Applications:
Single H2S detector is an intrinsically safe and explosion-proof instrument and is designed to deter H2S.
Single H2S detector is a low-cost, maintenance-free single gas monitor designed to protect personnel from dangerous H2S gas exposure in the most extreme conditions. Despite its compact size, the single H2S detector includes features usually found only in larger multi-gas monitors including a large, OLED display, internal audible/visual alarms and simple push-button operation.
The monitor continuously displays ambient combustible gas readings and will alert the user when gas concentrations exceed the preset low or high levels. Added features include adjustable alarm setpoints, calibration gas values, and choice of text-only display selected by the user through a simple, push-button routine. Single H2S detector also has a peak/hold feature to show the highest reading during a shift and includes a special flip-cap calibration adapter for quick and simple calibration. Single H2S detector is covered by a two-year warranty from the date of manufacture.
It is used at the underground coal mine and mine safety inspection mainly. Certainly, it is also applied to fire fighting, confined space, chemical industry, oil and all kinds of environment that needed to measure the combustible gas.
