Qhov tseeb xaiv ntawm portable gastectors
1. Cov hauv paus ntsiab lus ntawm cov roj txuas nrog cov roj sib txuas yog cov kev sib xyaw ua ke, uas yog qhov kev paub zoo heev. Ntsuas qhov ntsuas kuj yooj yim heev. Txij li cov thev naus laus zis tau nthuav dav, cov qauv siv roj av tau tuaj yeem ua tau raws li cov neeg yuav tsum tau ua.
Hauv qab no yog kev ua haujlwm thiab txawv teb chaws Portable Compensible Gas Lub Suab Tswb lav tau uas tau txais kev txheeb xyuas zoo los ntawm cov neeg siv:
Cov lus pom zoo hauv tsev: JL268D, JL269 DRECTES, ADY-1, thiab HL-200 series kuj tau txais cov lus qhia zoo los ntawm cov neeg siv.
Imported recommendations: The MC-W combustible gas alarm instrument from BW Company in Canada; lub impulsex1 Ntes los ntawm honeywell; XP - 3110 ntes, xp - 3160 Twj-XIM-3140 eak ntes los ntawm comcos; Lub miniex combustible gas ntes los ntawm rae systems; Tus ex2000 Ntes los ntawm Oldham; Lub PAC Ex2 thiab X-sawv daws 2000 combustible Gas Tswb Tsuaj Cov Khoom Siv los ntawm Drager.
2. Yog tias muaj qee cov roj lom xws li carbon monoxide, ammonia, oxygine extector lossis ib qho portable multi {2} Lub portable multi {2} Lub portable multi} Cov tshuaj portable, thiab lwm yam xaiv los xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Kev kuaj cov roj toxic siv cov tshuab hluav taws xob hluav taws xob rau kev kuaj pom. Cov kev ntsuas los ntawm cov tshuaj lom neeg ntsuas roj raws li cov qauv electrochemical feem ntau yog hauv PPM units.
Nco tseg: Thaum kuaj pom cov roj lom cov roj lom, tshwj tsis yog cov pa roj carbon monoxide thiab oxygen, nws raug nquahu kom siv cov twj paj nruag hauv tsev rau lwm cov roj to.
Cov lus pom zoo txawv teb: tus gaxt series ntawm ib leeg toxic roj suab seev ntawm BW; tus impulsexp tib ntes los ntawm honeywell; Lub T40 Ntes los ntawm MSA; Lub TX2000 ib qho ntes los ntawm Oldham; Lub PAC 5000, Pac7000, thiab PAC ⅲ ib qho kev ntsuas roj toxic rad toxic los ntawm cov kua ntoo.
3. If there are more organic toxic and harmful gases, considering that their concentrations that may cause personnel poisoning are relatively low, such as aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, esters, etc., a photoionization detector should be selected, and never use an LEL detector to deal with them, because this may lead to casualties.
Cov lus pom zoo txawv teb: PGM-7600 NTES, PGM-30 NTES, PGM-7320 NTES los ntawm RAA system, thiab cov organic roj ntes los ntawm ion science nyob rau hauv UK.
4. Yog tias cov hom pa roj npog saum toj no - hais cov roj av, cov pa sib xyaw ua ke yuav tsum raug xaiv. Hom kev ntes no yuav tsum tau muab cov pa roj sib xyaw ua ke ntawm qhov chaw ntsuas kom cov sensors tuaj yeem ua tau zoo dua.
Cov lus pom zoo txawv teb: M5PID cov qauv kuaj ntawm BW hauv Canada, PGM-}}}}}} organic compound ntes los ntawm rae tshuab.
