Portable gas detector, cov ntsiab lus tseem ceeb ntawm kev paub nrov
Portable Gas Detector yog ib qho tseem ceeb thiab siv tau cov cuab yeej, nws tuaj yeem tshawb xyuas qhov concentration ntawm cov pa nrog rau qhov kub thiab av noo thiab lwm yam tsis zoo, rau kev saib xyuas ib puag ncig thiab kev tiv thaiv kev nyab xeeb muab lub hauv paus tsim nyog. Kev ua tiav ntawm cov haujlwm no tsis tuaj yeem sib cais los ntawm cov khoom tseem ceeb ntawm lub tshuab ntsuas roj - roj sensor.
Gas sensor yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob portable. Raws li qhov sib txawv ntawm cov pa roj carbon monoxide yuav tsum ntsuas, qhov ntsuas qhov tseeb thiab qhov yuav tsum tau ua ntawm kev ntsuas ntau, cov hom roj sensors muaj nyob hauv khw muaj xws li catalytic combustion, electrochemical, thermal conductivity, infrared, thiab PID photo-ionization hom sensors. .
Catalytic combustion sensors yog cov khoom siv feem ntau siv los kuaj xyuas cov pa roj carbon monoxide, thiab lawv muaj cov txiaj ntsig zoo ntawm cov zis tawm, tus nqi qis, thiab kev ywj pheej ntawm kev sib tham nrog lwm cov roj. Raws li lub hauv paus ntsiab lus ntawm Wheatstone choj, catalytic combustion sensors tsim cov kub kub uas hloov qhov kev tiv thaiv ntawm lub sensing resistor los ntawm flamelessly combusting cov roj nyob rau hauv kev ntsuam xyuas tiv thaiv tus sensing resistor, yog li outputting ib tug ruaj khov tam sim no teeb liab.
Electrochemical sensors yog siv dav hauv kev tshawb nrhiav cov pa roj carbon monoxide. Hom sensor no muaj qhov zoo ntawm kev ua haujlwm ruaj khov, kev siv hluav taws xob tsawg, qhov tseeb zoo thiab tsis yooj yim los ntawm lwm cov pa roj. Nws tuaj yeem hnov mob nrog cov pa ntsuas thiab tsim hluav taws xob teeb liab proportional rau cov roj concentration.
Tsis tas li ntawd, infrared-type sensors siv cov cuab yeej nqus nqus ntawm cov pa roj hauv qhov ze-infrared spectrum los txiav txim siab cov pa roj los ntawm kev ntsuas kev sib raug zoo ntawm cov roj concentration thiab qhov nqus nqus. Hom sensor no muaj cov txiaj ntsig zoo xws li lub neej ntev, kev nkag siab zoo dua, kev ruaj ntseg zoo dua thiab kev saib xyuas yooj yim.
PID lub teeb ionization sensor los ntawm UV lub teeb qhov chaw yuav cov roj ionization tuaj yeem kuaj pom los ntawm tus ntes ntawm cov ions zoo thiab tsis zoo, thiab tom qab ntawd tus nqi kuaj pom yuav raug hloov mus rau hauv lub teeb liab tam sim no, thiab tom qab qhov sib thooj algorithm los hloov cov concentration ntawm cov nqi roj. .PID sensor siab precision, tuaj yeem ntes cov ppb qib ntawm cov roj concentration, cov lus teb ceev ceev, thiab feem ntau yog siv rau hauv kev tshawb nrhiav VOC volatile organic compounds. Txawm li cas los xij, vim nws qhov kev ua tau zoo thiab cov thev naus laus zis siab heev, tus nqi ntawm PID sensor yog qhov siab.
Txhawm rau kom ua tiav, cov roj sensors, cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob portable, ua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav cov roj sib txawv. Ntau hom sensors muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, cov neeg siv yuav tsum xaiv lub sensor haum tshaj plaws raws li qhov chaw ua haujlwm thiab xav tau thaum yuav khoom. Thaum kawg, nws tsim nyog hais tias lub twj tso kua mis-hom 5-hauv-1 roj ntes ERUN-PG71S5 tsim los ntawm WinRun Environmental Protection Company yog cov cuab yeej siv ntau yam thiab ua haujlwm siab, uas yog siv dav hauv cov teb ntawm petrochemicals, tshuaj, kev tiv thaiv ib puag ncig, flue gas tsom, kev kho cua, thiab lwm yam. Nws tsim nyog pom zoo.
