德國AFRISO檢測儀 500ST-C3H8 69120
氣體檢測儀作為一種重要的安全設(shè)備，能夠檢測多種氣體，主要包括可燃易爆氣體、有毒有害氣體和氧氣。這些氣體的監(jiān)測對于保障工作場所的安全和員工的健康至關(guān)重要。
可燃易爆氣體是指在一定條件下能夠燃燒或爆炸的氣體，如氫氣、甲烷、乙烷、乙炔等氣體，以及易揮發(fā)的可燃液體，如甲醇、甲醚、苯等。這些氣體在空氣中達(dá)到一定濃度后，遇到明火或高熱就會發(fā)生燃燒或爆炸，容易引發(fā)火災(zāi)和爆炸事故，造成人員傷亡和財(cái)產(chǎn)損失。不同氣體的爆炸極限不同，可以通過《GB 50058-2014爆炸危險(xiǎn)環(huán)境電力裝置設(shè)計(jì)規(guī)范》查詢相應(yīng)的爆炸范圍，根據(jù)氣體的爆炸下限設(shè)置可燃?xì)怏w報(bào)警值。
有毒有害氣體是指對人體有毒有害的氣體，包括刺激性氣體和窒息性氣體。刺激性氣體如、、二氧化硫等，容易引起呼吸道和眼睛刺激，泄漏后會造成人員中毒。窒息性氣體如氮?dú)、甲烷、一氧化碳、硫化氫等，會降低空氣中的氧氣濃度，?dǎo)致缺氧甚至窒息。有害氣體的職業(yè)接觸限值是指人類長期接觸有害氣體的限值，一旦超過這個(gè)數(shù)值就會引起中毒等情況。有害氣體檢測儀可以根據(jù)有害氣體的職業(yè)接觸限值來設(shè)置報(bào)警值，一旦超限就會發(fā)出報(bào)警信號提醒人們。
氧氣是維持生命所必需的氣體，但過高或過低的氧氣濃度都會對人體產(chǎn)生危害。環(huán)境中的氧氣濃度在19.5%-23.5%之間最適宜，低于19.5%會導(dǎo)致缺氧，高于23.5%則會引起氧中毒的可能。因此，氧氣檢測儀在設(shè)置報(bào)警值時(shí)一般將23.5%設(shè)置為環(huán)境過氧報(bào)警設(shè)定值，19.5%設(shè)置為環(huán)境欠氧報(bào)警設(shè)定值。
一種常用的氣體檢測儀是ERUN-QB9630手提式多參數(shù)有害氣體檢測儀，它能夠同時(shí)檢測18種不同氣體。該檢測儀采用國際知名進(jìn)口品牌的傳感器，具有響應(yīng)快、精度高、測量結(jié)果準(zhǔn)確的特點(diǎn)。同時(shí)，該檢測儀具有IP66級防護(hù)和本安型防爆設(shè)計(jì)，使用安全可靠。
綜上所述，氣體檢測儀可檢測的氣體種類非常多，包括可燃易爆氣體、有毒有害氣體和氧氣。這些氣體的監(jiān)測對于保障工作場所的安全和員工的健康至關(guān)重要。使用合適的氣體檢測儀能夠及時(shí)發(fā)現(xiàn)氣體超標(biāo)情況，提前預(yù)警，降低事故發(fā)生的概率。在使用過程中，還需定期檢定氣體檢測儀，以確保其準(zhǔn)確性和可靠性。
