Carbon monoxide in detection air has important value. On the one hand, carbon monoxide is scentless, but has high toxicity simultaneously. Therefore, for carbon monoxide, present maximum work space concentration is only 30ppm. Now, if there is burner or chimney in indoor, at imperfect combustion, when namely lacking air, in flue gas, carbonomonoxide concentration is probably the percent by volume of several. If smoke pipe blow-by or device chimney exhaust gas are due to disadvantageous pressure dependence, for instance owing to the chimney adversely extended or operation nearby have smoke exhaust ventilator, and leak into indoor, then can be formed and cause poisoning carbonomonoxide concentration. This is enough to cause Health cost or even death due to poisoning in the most adverse case.Such as CDC is in " carbon monoxide poisoning: fact sheet provides: have 500 people dead due to carbon monoxide poisoning every year in the U.S.. Also substantial amounts of carbon monoxide can be formed when smoldering. Except personnel's toxic hazard, therefore this gas indicate gas used also as fire and be therefore also used to its detection find fire condition ahead of time.
At present, room air detecting instrument instrument key circuit possesses two aspect functions, requires when system boot on the one hand, the input block of man-machine interaction is provided, it is then under system closedown power-down conditions on the other hand, gives and provide an of short duration powered on moment with system, to realize power up function. Owing to portable apparatus is high for space requirement, when instrument finite volume, it is difficulty with the key circuit of many buttons, in order to solve problems, on market, a lot of instruments have employed the pattern of single-button, machine volume can be reduced although it is so, but owing to single-button mode is when expressing multiple meaning, the button length time can only be used to make a distinction, and this just brings a lot of troubles, complicated operation to operator, difficult memory, error-prone, most key part is also easily intake, the especially easy damage of instrument.
