Muaj peev xwm ntes tau roj nrog lub tshuab ntes tau
Ua hauj lwm hauv paus ntsiab lus ntawm portable gas detector
Electrochemical gas detectors yog cov khoom siv hluav taws xob siv hluav taws xob hluav taws xob. Txij li thaum muaj ntau cov gases yog electrochemically active, lawv muaj peev xwm yuav electrochemically oxidized los yog txo, thiab tam sim no generated los ntawm cov tshuaj tiv thaiv yog proportional rau cov concentration ntawm cov roj reacts. , 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 ua tau zoo thiab cov lus teb ceev ceev, thiab feem ntau yog siv rau kev tshawb nrhiav cov pa roj carbon monoxide, tab sis muaj ntau 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 xyuas seb puas muaj roj txaus ntshai (flammable, explosive, poisonous) nyob rau hauv ib qho chaw. 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 qho haujlwm tseem ceeb los tiv thaiv kev ua tsis tiav.
Portable gas detector tuaj yeem ntes roj
Portable gas detector tuaj yeem ntes hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone thiab combustible gases thiab lwm yam gases, dav siv nyob rau hauv petrochemical, On-site nrhiav tau nyob rau hauv cov thee. , metallurgy, tshuaj lom neeg kev lag luam, roj hauv nroog, kev saib xyuas ib puag ncig thiab lwm qhov chaw.
Kev pab lub neej ntawm portable gas detector
Lub neej kev pab cuam ntawm lub portable gas detector feem ntau yog nyob ntawm lub core tivthaiv sensor. Nws tuaj yeem muab faib ua roughly faib rau hauv: sensors rau kev kuaj xyuas qhov concentration ntawm cov pa roj carbon monoxide thiab cov sensors rau kev kuaj xyuas qhov tawg ntawm cov roj hluav taws xob. Lub sensor siv los txheeb xyuas qhov concentration ntawm cov roj combustible yog catalytic combustion sensor, thiab nws lub neej kev pab yog 3 mus rau 5 xyoo. Lub sensor rau kuaj cov pa roj yog ib hom electrochemical, feem ntau 1 txog 2 xyoos.
