，在zai試shi驗yan結jie束shu後hou必bi須xu將jiang氧yang傳chuan感gan器qi內nei氣qi體ti的de氧yang含han量liang降jiang到dao最zui低di
，若ruo儀yi器qi近jin期qi還hai要yao做zuo試shi驗yan，可ke先xian用yong大da流liu量liang載zai氣qi對dui測ce試shi腔qiang進jin行xing吹chui掃sao然ran後hou再zai把ba載zai氣qi流liu速su調tiao小xiao並bing持chi續xu吹chui掃sao係xi統tong以yi防fang止zhi外wai界jie氧yang氣qi的de滲shen入ru；若近期不使用設備隻有在確認氣流的氧含量足夠少時（如係統被高純氮氣吹掃2小時以上），才可關閉氧傳感器保護閥然後關閉鋼瓶輸出閥停止供氣。Labthink係xi列lie等deng壓ya法fa設she備bei設she置zhi了le雙shuang重zhong氧yang傳chuan感gan器qi保bao護hu措cuo施shi
，大da大da改gai良liang了le密mi封feng效xiao果guo。然ran而er由you於yu傳chuan感gan器qi的de損sun耗hao直zhi接jie影ying響xiang測ce試shi數shu據ju的de準zhun確que性xing，所suo以yi等deng壓ya法fa設she備bei必bi須xu定ding期qi標biao定ding。 
  
   還hai需xu特te別bie注zhu意yi的de一yi點dian是shi
，等deng壓ya法fa設she備bei無wu論lun是shi在zai測ce試shi過guo程cheng中zhong還hai是shi在zai試shi驗yan結jie束shu之zhi後hou總zong需xu要yao用yong大da量liang載zai氣qi吹chui掃sao測ce試shi係xi統tong
，因yin此ci試shi驗yan尾wei氣qi排pai放fang量liang相xiang當dang大da，所suo以yi必bi須xu注zhu意yi對dui尾wei氣qi的de處chu理li。應ying該gai使shi用yong導dao氣qi管guan連lian接jie儀yi器qi的de尾wei氣qi出chu氣qi口kou並bing將jiang尾wei氣qi引yin到dao室shi外wai，同tong時shi應ying注zhu意yi室shi內nei的de空kong氣qi循xun環huan，保bao持chi空kong氣qi清qing新xin。 
  
   第di三san，現xian在zai的de等deng壓ya法fa設she備bei普pu遍bian具ju有you對dui測ce試shi氣qi體ti溫wen濕shi度du的de控kong製zhi功gong能neng，對dui測ce試shi氣qi體ti控kong濕shi不bu可ke避bi免mian地di要yao在zai氣qi路lu中zhong增zeng加jia濕shi度du發fa生sheng物wu質zhi，而er在zai氣qi路lu中zhong長chang時shi間jian存cun有you濕shi氣qi不bu利li於yu設she備bei維wei護hu，因yin此ci在zai加jia濕shi試shi驗yan結jie束shu之zhi後hou需xu要yao將jiang濕shi度du增zeng加jia裝zhuang置zhi中zhong的de濕shi度du發fa生sheng物wu質zhi清qing除chu幹gan淨jing並bing用yong幹gan燥zao氮dan氣qi吹chui淨jing係xi統tong中zhong的de濕shi氣qi。

       縱上所述，壓差法、稱重法
、以及濕度傳感器法維護方便簡單，隻需進行常規的維護操作就可以了。但是對於等壓法、紅外傳感器法
、以及電解傳感器法必須注意傳感器的保護、試驗尾氣的處理
、測ce試shi係xi統tong內nei雜za質zhi氣qi體ti的de清qing除chu等deng幾ji個ge方fang麵mian
