Kev xaiv cov khoom siv hluav taws xob hluav taws xob yuav tsum tau ua nrog ceev faj.
Portable gas detectors tuaj yeem siv dav hauv kev lag luam xws li petrochemicals, kev tsim khoom lag luam, pa luam yeeb thiab tso pa ib puag ncig, kev kho dej phwj tuaj, biopharmaceuticals, kev tiv thaiv ib puag ncig hauv tsev, tsev kawm ntawv chav kuaj, thiab lwm yam. Nyob rau tib lub sijhawm, lawv tau nruab nrog lub twj tso kua mis tso kua roj, uas muab cov txiaj ntsig zoo dua thiab nrawm dua.
Thaum siv lub tshuab ntsuas roj portable, cov neeg siv yuav tsum xyuam xim rau peb lub ntsiab lus hauv qab no:
1. Ua tib zoo saib xyuas qhov ntsuas qhov ntsuas ntawm lub tshuab hluav taws xob portable siv:
Txhua lub tshuab ntsuas roj muaj qhov ntsuas qhov ntsuas ruaj khov, thiab tsuas yog nyob rau hauv qhov kev ntsuas no tuaj yeem ua tiav. Txwv tsis pub, cov txiaj ntsig ntsuas yuav qis dua li qhov tseem ceeb hauv koj ib puag ncig. Tsis tas li ntawd, kev ntsuas ntev dhau ntawm qhov ntau tuaj yeem ua rau muaj kev puas tsuaj rau lub sensor, uas ua rau cov txiaj ntsig tsis raug txawm tias nyob hauv qhov ntsuas qhov ntsuas tom qab.
2. Ua tib zoo saib xyuas lub neej kev pab cuam ntawm cov sensors hauv cov roj ntes siv:
Gas detectors muaj qhov txwv ntawm lawv lub neej kev pab cuam, thiab portable gas detectors tsis muaj kev zam. Txawm hais tias lawv tsis siv ntau zaus, lawv tseem tuaj yeem ntsib kev laus. Nyob rau hauv dav dav, ntawm portable gas detectors, photoionization detectors muaj lub neej ntev tshaj ntawm plaub xyoos; Kev pabcuam lub neej ntawm LEL sensors yog thib ob, thiab lawv tuaj yeem siv tau ntau tshaj peb xyoos; Lub neej ntawm electrochemical tshwj xeeb roj sensors yog luv luv, feem ntau ntawm ib mus rau ob xyoos; Cov pa oxygen sensor tsuas yog siv tau li ntawm ib xyoos xwb.
Yog li, ua ntej siv, nco ntsoov nyeem phau ntawv kom zoo thiab siv lub sensor nyob rau hnub tas sij hawm. Yog tias pom tias nws tas sij hawm, nws yuav tsum tau hloov tam sim ntawd.
3. Tsis tu ncua calibration thiab kuaj ntawm lub detector yuav tsum tau:
Portable gas detectors feem ntau siv cov kev sib piv piv rau kev ntsuas, raws li hauv qab no:
1. Ua ntej, calibrate lub ntsuas nrog tus qauv concentration ntawm cov pa thiab xoom roj, thiab khaws cov qauv nkhaus hauv qhov ntsuas;
2. Sib piv cov teeb liab hluav taws xob ntawm tus qauv concentration nrog cov teeb liab hluav taws xob tsim los ntawm kev ntsuas roj concentration, thiab xam qhov tseeb roj concentration tus nqi.
