Portable VOC Gas Detector siv nyob rau hauv ib puag ncig?
Portable VOC detectors tau ua rau peb lub neej yooj yim dua, tab sis qhov kev sim sib txawv li cas cuam tshuam rau portable VOC detectors? Yog li qhov chaw nyob uas lub portable VOC gas detector siv?
Portable VOC Gas Detectors yuav tsim lub sijhawm sib txawv rau qhov chaw sib txawv raws li hauv qab no:
VOC yog saturated vapor siab nyob rau hauv chav tsev kub tshaj 133.32pa, boiling point ntawm 50 degree -250 degree, yuav evaporated nyob rau hauv daim ntawv ntawm cov organic teeb meem tam sim no nyob rau hauv cov huab cua. Lub ntsiab tseem ceeb ntawm lub portable VOC gas detector yog PID (photoionization) sensor, uas muaj tag nrho ntawm 5 ntau yam xaiv tau los ntawm 0-20ppm, 0-50ppm, 0-200ppm, {{8} }}ppm, 0-10, 000ppm, thiab tuaj yeem raug rau qib PPb.
Thaum lub portable VOC roj ntes tau qhib thawj zaug, TVOC yog grey (feem ntau yog dub) vim TVOC yuav tsum tau sov so li 20 feeb thiab siv sij hawm ntev me ntsis kom pom cov ambient concentrations.
Sensors muaj qhov sib txawv ntawm lub cev ruaj khov nyob rau hauv ib puag ncig sib txawv, yog li ua ntej xaiv ib qho cuab yeej, nco ntsoov xyuas ib puag ncig nws yuav sim thiab yuav cov khoom sib txawv rau ntau qhov chaw. Raws li kev txheeb xyuas qhov tseeb ntawm cov ntsuas qis qis yog qhov siab heev, tab sis qhov tseeb ntawm qhov ntsuas qhov siab ntawm qhov ntsuas siab yuav tsum qis dua.
1. Yog tias koj sim TVOC hauv huab cua sab hauv, koj feem ntau xaiv ib qho 0-20 ppm lossis 0-50 ppm sensor, tau kawg, qhov 0-20 ppm sensor. Vim tias TVOC cov ntsiab lus hauv huab cua sab hauv tsev tsawg heev, yuav tsum muaj lub sensor los ntsuas qhov tseeb;
2, yog tias qhov concentration ntawm cov pa phem ntau heev, yog tias muaj qhov xau, ces koj xav tau qhov ntau ntawm TVOC sensor 0-10000 ppm. TVOC sensor;
3, thaum kuaj huab cua sab nraum zoov, TVOC feem ntau pom zoo 0-50 ppm lossis 0-200 ppm sensor. Yog tias pom qhov muaj kuab paug, ib qho 0 0-2000 ppm sensor feem ntau pom zoo.
