Kev ua tau zoo ntawm cov pa roj carbon monoxide detectors
Cov pa roj carbon monoxide tuaj yeem ua rau peb tib neeg noj qab haus huv. Yog tias carbon monoxide lom heev, nws tuaj yeem ua rau tuag taus. Hauv qhov no, yuav tsum muaj lub ntsuas carbon monoxide. Lub luag haujlwm tseem ceeb ntawm lub ntsuas pa roj carbon monoxide yog txhawm rau txheeb xyuas qhov concentration ntawm carbon monoxide nyob rau hauv qhov chaw ua haujlwm. Thaum cov pa roj carbon monoxide nyob rau hauv qhov chaw ua haujlwm tshaj qhov kev nyab xeeb ntawm cov pa roj carbon monoxide detector, cov pa roj carbon monoxide detector yuav xa tawm lub tswb ceeb toom ceeb toom rau cov neeg ua haujlwm hauv chaw ua haujlwm kom xyuam xim rau kev tiv thaiv thiab ntsuas qhov tsim nyog thaum muaj xwm txheej ceev. Yog li dab tsi yog qhov yuav tsum tau ua haujlwm rau carbon monoxide detectors?
1. Qhov ntsuas qhov ntsuas ntawm cov pa roj carbon monoxide nyob rau hauv kev siv ib txwm yuav tsum ncav cuag 0-2000umol/mol, thiab qhov ntsuas MAX tus nqi yuav tsum tsis pub tsawg dua 2000umol/mol.
2. Qhov ntsuas tus nqi yuam kev ntawm cov khoom siv roj carbon monoxide raug xaiv los ntawm tus neeg siv yuav tsum nyob hauv thaj tsam ntawm ± 5umol / mol, thiab tus txheeb ze yuam kev yuav tsum nyob hauv thaj tsam ntawm ± 10%. Qhov tseeb dua qhov kev nyeem ntawv ntawm qhov ntsuas, qhov zoo dua nws tuaj yeem qhia qhov concentration ntawm cov pa.
3. Lub sij hawm teb ntawm cov pa roj carbon monoxide gas detector nyob rau hauv ib txwm siv yuav tsum ua raws li cov qauv hauv qab no: lub sij hawm teb ntawm diffusion carbon monoxide gas detector yuav tsum tsawg dua 60 vib nas this, thiab lub sij hawm teb ntawm lub nqus pa roj carbon monoxide gas detector yuav tsum yog. tsawg dua los yog sib npaug li 30s.
4. Lub drift degree ntawm cov pa roj carbon monoxide detector yuav tsum nyob rau hauv ntau yam nram qab no: xoom taw tes drift yuav tsum yog ± 3umol / mol, thiab ntau drift yuav tsum yog ± 5%.
