Portable Gas Detector tuaj yeem tshawb xyuas qhov muaj roj
Electrochemical gas detectors yog cov khoom siv hluav taws xob uas siv cov khoom siv hluav taws xob. Txij li thaum muaj ntau cov gases yog electrochemically active thiab yuav ua tau electrochemically oxidized los yog txo, tam sim no generated los ntawm cov tshuaj tiv thaiv yog proportional rau cov concentration ntawm cov reacted gas. , yog li qhov muaj pes tsawg leeg thiab concentration ntawm cov roj tuaj yeem kuaj pom los ntawm hom tshuaj tiv thaiv no. Txoj kev tshawb nrhiav no muaj qhov raug siab thiab teb ceev ceev. Nws feem ntau yog siv rau kev tshawb nrhiav cov pa phem. Txawm li cas los xij, cov tshuaj tiv thaiv electrochemical kuj muaj cov kev faib tawm sib txawv. Cov hauv qab no qhia txog hom kev siv tshuaj tiv thaiv electrochemical feem ntau thiab cov ntsiab cai ntawm electrochemical gas detectors.
Lub portable gas detector yog ib qho cuab yeej siv los txheeb xyuas qhov muaj cov pa phem (flammable, explosive, toxic) nyob rau ib puag ncig. Rau cov pa phem uas muaj nyob hauv qhov chaw kuaj pom. Kev tu vaj tse yog ib txoj haujlwm tseem ceeb los txhim kho kev ruaj ntseg, raug thiab lub neej ntawm cov cuab yeej ntsuas. Nws kuj yog ib txoj haujlwm tseem ceeb los tiv thaiv kev ua tsis tiav.
Portable gas detector tuaj yeem ntes roj
Lub portable gas detector tuaj yeem ntes tau ntau yam roj xws li hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone thiab combustible gases. Nws yog dav siv nyob rau hauv petrochemical, On-site soj ntsuam nyob rau hauv thee, metallurgy, chemical kev lag luam, municipal gas, ib puag ncig xyuas thiab lwm qhov chaw.
Kev pab lub neej ntawm portable gas detectors
Lub neej kev pab cuam ntawm lub portable gas detector feem ntau yog nyob ntawm lub core tivthaiv sensor. Lawv tuaj yeem muab faib ua roughly faib rau hauv: cov sensors uas kuaj pom qhov concentration ntawm cov pa roj carbon monoxide thiab cov sensors uas pom qhov tawg ntawm cov nplaim hluav taws. Cov sensors siv los txheeb xyuas qhov concentration ntawm cov roj hluav taws xob muaj xws li catalytic combustion sensors, uas muaj lub neej ua haujlwm ntawm 3 txog 5 xyoos. Cov sensors uas ntes cov pa phem siv cov khoom siv hluav taws xob electrochemical, uas feem ntau kav ntev li 1 txog 2 xyoos.
