一、氢气气体检测仪CQH100矿用带煤安证防爆证简 介
氢气是井下*轻的有害气体?？掌星馄ǘ却锏?%~74%时具有爆炸危险。井下氢气的主要来源是变压器和蓄电池充电。此外，矿井发生火灾和爆炸事故中也会产生。
CQH100用于矿井中氢气的检测，如用在变压器、井下变电站、机房、可用于矿井火灾中标志气体的检测与分析，也可以发生爆炸后的救援场合，它采用进口的电化学传感器，反应灵敏，准确可靠。 仪器采用坚固的工程塑料外壳和良好的?；ど杓?，能使用在诸如具有瓦斯粉尘的爆炸性环境中。仪器小巧轻便，能很容易的夹住皮带，衬衫口袋或**帽上。超大高亮度OLCD液晶在黑暗的井下依然清晰可见，可读出气体浓度、时间、电量等数据。如果当前气体浓度值超出预设限度值时，仪器以声、光报警提醒用户。
试用场所：适于有瓦斯爆炸和煤与瓦斯突出危险的场合，包括井下变压器、供电站、变电站、矿山救护、煤矿采掘工作面、回风巷道等使用。

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.
