可燃(ran)氣(qi)(qi)體(ti)(ti)(ti)探測(ce)儀(yi)主要采(cai)用(yong)(yong)以(yi)下幾種(zhong)(zhong)檢(jian)測(ce)方(fang)法(fa)：1.催(cui)化(hua)(hua)燃(ran)燒法(fa)：通過(guo)(guo)催(cui)化(hua)(hua)燃(ran)燒原理，當(dang)可燃(ran)氣(qi)(qi)體(ti)(ti)(ti)遇到高(gao)溫(wen)催(cui)化(hua)(hua)劑時，發生(sheng)氧化(hua)(hua)反應(ying)，產生(sheng)熱量，氣(qi)(qi)體(ti)(ti)(ti)檢(jian)測(ce)單位，通過(guo)(guo)測(ce)量這種(zhong)(zhong)熱量變化(hua)(hua)來判斷氣(qi)(qi)體(ti)(ti)(ti)濃(nong)(nong)(nong)度。2.紅(hong)外(wai)(wai)吸收法(fa)：利(li)用(yong)(yong)紅(hong)外(wai)(wai)光譜特性(xing)，不(bu)(bu)同(tong)氣(qi)(qi)體(ti)(ti)(ti)對特定(ding)波長的紅(hong)外(wai)(wai)輻射有不(bu)(bu)同(tong)的吸收率，通過(guo)(guo)比較紅(hong)外(wai)(wai)光強度的變化(hua)(hua)來識別和(he)(he)測(ce)量可燃(ran)氣(qi)(qi)體(ti)(ti)(ti)。3.電(dian)(dian)化(hua)(hua)學傳感器法(fa)：通過(guo)(guo)電(dian)(dian)化(hua)(hua)學反應(ying)，如(ru)燃(ran)料(liao)(liao)電(dian)(dian)池或(huo)固態電(dian)(dian)解質，檢(jian)測(ce)氣(qi)(qi)體(ti)(ti)(ti)與電(dian)(dian)極之間(jian)(jian)的化(hua)(hua)學反應(ying)，從而得(de)出(chu)氣(qi)(qi)體(ti)(ti)(ti)濃(nong)(nong)(nong)度。4.光離子(zi)化(hua)(hua)檢(jian)測(ce)法(fa)（PID）：利(li)用(yong)(yong)高(gao)能(neng)量光照射可燃(ran)氣(qi)(qi)體(ti)(ti)(ti)分子(zi)，使(shi)其離解成帶電(dian)(dian)離子(zi)，通過(guo)(guo)收集和(he)(he)測(ce)量這些(xie)離子(zi)，確(que)定(ding)氣(qi)(qi)體(ti)(ti)(ti)濃(nong)(nong)(nong)度。5.霍爾效(xiao)應(ying)傳感器：通過(guo)(guo)霍爾效(xiao)應(ying)原理，測(ce)量磁場中氣(qi)(qi)體(ti)(ti)(ti)的磁導率變化(hua)(hua)，間(jian)(jian)接反映可燃(ran)氣(qi)(qi)體(ti)(ti)(ti)的存在。6.膜(mo)電(dian)(dian)阻(zu)原理：氣(qi)(qi)體(ti)(ti)(ti)與敏(min)感膜(mo)材(cai)料(liao)(liao)發生(sheng)物(wu)理或(huo)化(hua)(hua)學反應(ying)，導致電(dian)(dian)阻(zu)值變化(hua)(hua)，以(yi)此檢(jian)測(ce)氣(qi)(qi)體(ti)(ti)(ti)濃(nong)(nong)(nong)度。每種(zhong)(zhong)方(fang)法(fa)各有優(you)缺點，適用(yong)(yong)于不(bu)(bu)同(tong)的應(ying)用(yong)(yong)環境和(he)(he)氣(qi)(qi)體(ti)(ti)(ti)類(lei)型。現代的可燃(ran)氣(qi)(qi)體(ti)(ti)(ti)探測(ce)儀(yi)通常會結合(he)多種(zhong)(zhong)檢(jian)測(ce)技術，以(yi)提高(gao)準(zhun)確(que)性(xing)和(he)(he)可靠性(xing)。
