<strong><a href="http://www.qdjlst.com/shzmhb-Products-18286509/">氣體檢測儀</a></strong>行業(yè)技術(shù)體現(xiàn)在以下兩個方面：<div> 1、<strong>氣體檢測儀</strong>使用的傳感器不同</div><div> 傳感器技術(shù)涉及光、熱、力、電壓、磁、氣、濕、聲、射線、離子等敏感技術(shù)領(lǐng)域，過去相當一段時間里，由于氣體傳感器自身難以與測量環(huán)境物理隔離等原因，氣體傳感器的技術(shù)成熟度和產(chǎn)業(yè)化滯后，也制約了氣體傳感器及氣體檢測儀器儀表的實際應(yīng)用范圍。而近年來技術(shù)的不斷進步、日益迫切的市場需求和巨大的市場空間，使氣體傳感器及<strong>氣體檢測儀</strong>器儀表的技術(shù)研發(fā)和產(chǎn)業(yè)化成為的熱點，產(chǎn)品使用越來越廣泛。過去氣體傳感器主要用于煤氣、液化石油氣、天然氣以及礦井中的瓦斯氣體的檢測與報警，目前需要檢測的氣體種類由原來的還原性氣體(H2，C4H10，CH4等)擴展到毒性氣體(CO，NO2，H2S，NO，NH3，PH3等)。氣體傳感器種類繁多，從原理上可以分為三大類：(1)利用物理化學(xué)性質(zhì)的氣體傳感器:如半導(dǎo)體、催化燃燒等。(2)利用物理性質(zhì)的氣體傳感器:如熱導(dǎo)、光干涉、紅外吸收等。(3)利用電化學(xué)性質(zhì)的氣體傳感器:如電流型、電勢型等。</div><div> 2、<strong>氣體檢測儀</strong>技術(shù)水平不同</div><div> 氣體檢測儀的生產(chǎn)必須滿足GBl5322—2003標準．然而GBl5322-2003標準只是規(guī)定的<strong>氣體檢測儀</strong>生產(chǎn)的zui低標準．有的產(chǎn)品只能滿足該標準．有的產(chǎn)品在該標準的基礎(chǔ)上增加了很多功能．比如帶有預(yù)警功能，通過預(yù)警的方式提前引起用戶注意。在產(chǎn)品設(shè)計中考慮售后服務(wù)問題等?？傊瑯釉跐M足GBl5322-2003標準的基礎(chǔ)上，不同廠家的產(chǎn)品存在較大的差異．這不僅標志著不同廠家的技術(shù)勢力的不同，更代表著不同廠家對產(chǎn)品的理解程度的不同。</div>
