JJB30-2new hom Handheld laser tej thaj chaw deb methane gas leak detector
1. Txheej txheem cej luam
Lub Handheld laser tej thaj chaw deb methane gas leak detector siv tunable laser spectroscopy (TDLAS) thev naus laus zis kom sai thiab raug txheeb xyuas cov pa tawm hauv qhov deb ntawm 30 meters.Cov neeg ua haujlwm tuaj yeem tshawb pom qhov nyuaj-mus txog lossis txawm tias tsis tuaj yeem nkag mus rau thaj chaw nyab xeeb, xws li txoj kev tsis khoom, cov kav dej raug tshem tawm, cov ris tsho siab siab, cov kav xa mus ntev, thiab chav tsis muaj neeg siv.Kev siv tsis yog tsuas yog txhim kho kev ua tau zoo thiab kev soj ntsuam taug kev zoo, tab sis kuj tseem ua rau kev tshuaj xyuas uas yav dhau los tsis tuaj yeem nkag mus tau lossis nyuaj rau kev mus txog.
Cov khoom no yog tsim rau cov kav dej siv nyiaj siv ua haujlwm, cov risers lossis cov kav dej xa mus rau hauv qhov chaw nqaim yog qhov nyuaj rau ncav cuag, thiab ua rau muaj kev phom sij rau kev nyab xeeb;Nws yog qhov nyuaj rau kev muag cov xau sai sai thaum kho qhov xwm txheej ceev, ua rau muaj kev kub ntxhov hauv qhov chaw, thiab kev tshuaj xyuas cov kav dej txhua hnub siv sijhawm ntau thiab cov neeg ua haujlwm, kev ua haujlwm tsis zoo, cov khoom siv hluav taws xob yuav tsum rov ua dua lossis ncua sij hawm, thiab cov txheej txheem yog cumbersome thiab tsis tsim nyog.
2. Cov yam ntxwv
◆ Kev nyab xeeb theem: intrinsically ruaj ntseg tawg-pov thawj tsim;
◆ Kev kuaj pom qhov deb: nrhiav pom cov methane thiab methane-muaj roj to ntawm qhov deb ntawm 30 meters;
◆ Kev tshawb pom sai: lub sijhawm tshawb pom tsuas yog 0.1 vib nas this;
◆ Cov neeg raug siab: tshwj xeeb laser nrhiav, tsuas yog reacting rau methane roj, tsis cuam tshuam los ntawm ib puag ncig tej yam kev mob
◆ Yooj yim rau siv: tsis siv neeg tshawb pom thaum pib, tsis tas yuav muaj kev ntsuas raws sijhawm, kev saib xyuas yooj yim dawb
◆ Ib qho yooj yim mus nqa: tus tsim yog nyob rau hauv txoj kab nrog tib neeg-lub computer muaj nuj nqi, me me thiab yooj yim mus nqa
◆ Tus phooj ywg interface: system-based ua haujlwm interface, ze rau cov neeg siv;
◆Ranging muaj nuj nqi: integrated nrug ntsuas muaj nuj nqi;
◆ Kev ua haujlwm ntau dhau: ntau tshaj 10 teev ntawm kev sim tuaj yeem ua tiav hauv hom qauv;
◆ Tshem tau roj teeb kom hloov tau yooj yim thiab ncua sij hawm ua hauj lwm;
◆ 3.2 nti npo / kov npo hom
