Tshawb xyuas cov pa roj nrog lub tshuab nqus pa
Ua hauj lwm hauv paus ntsiab lus ntawm portable gas detector
Electrochemical Gas Detector yog lub ntsuas roj uas siv cov ntsuas hluav taws xob hluav taws xob. Vim yog cov kev ua haujlwm ntawm electrochemical ntawm ntau cov pa roj, lawv tuaj yeem raug electrochemically oxidized los yog txo, thiab tam sim no generated los ntawm cov tshuaj tiv thaiv yog proportional rau cov concentration ntawm cov roj uas undergoes cov tshuaj tiv thaiv. Yog li ntawd, qhov muaj pes tsawg leeg thiab concentration ntawm cov pa roj tuaj yeem kuaj pom los ntawm cov tshuaj tiv thaiv zoo li no. Txoj kev tshawb nrhiav no muaj qhov raug siab thiab cov lus teb ceev ceev, thiab feem ntau siv rau kev tshawb nrhiav cov pa phem. Txawm li cas los xij, kuj tseem muaj qhov sib txawv ntawm cov tshuaj tiv thaiv electrochemical. 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 hauv kev txhim kho qhov ruaj khov, qhov tseeb, thiab lub neej ntev ntawm cov cuab yeej ntsuas. Nws kuj yog ib txoj haujlwm tseem ceeb los tiv thaiv kev ua haujlwm tsis zoo.
Portable gas detector tuaj yeem ntes cov pa roj
Portable gas detectors tuaj yeem ntes tau ntau yam roj xws li hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine gas, chlorine dioxide, ozone, thiab combustible gases. Lawv tau siv dav rau kev tshawb nrhiav nyob rau hauv ntau qhov chaw xws li petrochemicals, thee, metallurgy, tshuaj lom neeg kev lag luam, hluav taws xob hluav taws xob hauv nroog, thiab kev saib xyuas ib puag ncig.
Kev pab lub neej ntawm portable gas detectors
Lub neej kev pab cuam ntawm portable gas detectors feem ntau yog nyob ntawm lub core tivthaiv sensors. Nws tuaj yeem muab faib ua cov sensors txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm. 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 3-5 xyoo. Cov sensors siv los txheeb xyuas cov pa phem yog electrochemical, feem ntau yog 1-2 xyoo.
