Hauv kev ntsuas cov pa roj thiab kev nyab xeeb, ppm (lel (qis dua kev txwv tsis pub siv cov yam ntxwv ntawm hydrogen .
Tus Tsau Hydrogen Roj Ntes Puas yog kev nrhiav cov cuab yeej uas tuaj yeem ntsuas cov kev xav ntawm hydrogen nyob rau hauv huab cua thiab qhov sib txawv ntawm cov txiaj ntsig ntawm cov roj ntsha tau ntau dua li cov roj ntsha
The %LEL test measures the flammability (i.e., flammability and explosiveness) of hydrogen. It is set on the basis the lower explosive limit of hydrogen. The lower explosive limit is divided into 100 parts, and the range of 0-100%LEL is the detection range of the hydrogen alarm for Flammability . ntsuas ppm yog ntsuas cov tshuaj lom ntawm hydrogen {}}}} Kuv yog txhais tau tias yog ppm .
Rau kev ntsuas cov nplaim hluav taws (% lel), cov tshuaj ntsuam cov roj feem ntau muaj cov qauv kev sib txuas, nws yog qhov ntsuas ntawm cov ntsuas pa hluav taws xob, nws yog li kev ntsuas cov ntsuas pa Ntes raws li cov kev xav tau .
Peb lub tuam txhab, XI 'Huafan Technology co {}}, tau ua tiav kev nyab xeeb thiab kev ntsuas kev lag luam thiab tshuaj xyuas cov khoom siv tshuaj lom neeg thiab tshuaj ntsuam xyuas hauv cov khoom siv roj ntsha, ib puag ncig hauv cov khoom siv tshuaj lom neeg kev tsim khoom, muag khoom thiab kev pabcuam {4} Lub tuam txhab tau cog lus los ua cov khoom siv ntawm kev ua haujlwm thiab cov txheej txheem kev daws teeb meem hauv tsev thiab txawv teb chaws.
