Kev piav qhia ntawm cov ntsiab lus uas nquag siv rau cov khoom siv roj
Lub teb chaws tawg-pov thawj muaj cov kev cai meej ntawm ntau yam tawg-pov thawj cov khoom siv hluav taws xob tawg rau qhov chaw tawg.
d Hauv IICT6, d qhia tias hom tawg-pov thawj yog tawg-pov thawj.
II sawv cev rau lub Hoobkas khoom siv hluav taws xob, C sawv cev rau qib nruj tshaj plaws ntawm qhov ntsuas siab tshaj plaws los yog qhov tsawg kawg nkaus qhov hluav taws xob tam sim no piv (A, B, C peb theem) ntawm cov roj sib tov sib xyaw, thiab T6 sawv cev rau qib nruj tshaj plaws ntawm qhov siab tshaj plaws qhov kub thiab txias ( 85 degree)
Ib puag ncig tawg thiab cov khoom siv hluav taws xob tawg Cov khoom siv hluav taws xob tawg Qhov ib puag ncig uas muaj cov khoom tawg yog hu ua qhov chaw tawg. Cov khoom siv hluav taws xob tsim thiab tsim ua raws li cov xwm txheej tshwj xeeb uas tsis ua rau tawg ntawm ib puag ncig cov khoom sib xyaw ua kom tawg ua cov khoom siv hluav taws xob tawg rau qhov chaw tawg.
Cov khoom muaj feem xyuam rau cov khoom siv hluav taws xob uas siv tau Gas lub npe Molecular formula Specific gravity (air=1) TLV-TWA (PPM) TLV-STEL (PPM) TLV-IDLH (PPM) LEL (V%) HEL (V%)

Sensor preheating: Tom qab lub sensor yog powered on, qhov tso zis nqi yog tsis ruaj khov. Lub sij hawm tos tus nqi tso tawm kom ruaj khov ua sensor preheating.
Sensor Poisoning Thaum lub sensor yog powered on, yog hais tias nws los rau hauv kev sib cuag nrog ib tug roj uas nws concentration yog deb tshaj nws qhov ntau, nws yuav ua rau lub sensor tso zis nqi nyob rau hauv siab. Qee cov tshuaj lom neeg tuaj yeem rov qab tau tom qab lub sijhawm, thiab qee qhov ua tsis tau.
