Kev Piav Qhia Luv:
CD4 lub tshuab ntes roj tsis muaj hluav taws xob uas tsis tawg
[4G version] (4tiam neeg)
KHOOM QHIA TXOG
Lub tshuab ntes roj sib xyaw ua ke uas tsis muaj kev tawg (4G version) [tiam 4] tuaj yeem ntes tau tsib lub roj: methane CH4, oxygen O2.₂, carbon monoxide CO, hydrogen sulfide H₂S, thiab sulfur dioxide SO₂Nws qhia cov ntaub ntawv roj uas tau sau, qhov kub thiab txias ib puag ncig, thiab qhov chaw ntawm lub cuab yeej, xa cov ntaub ntawv no ntawm 4G mus rau lub platform rau kev tswj hwm wireless. Lub tshuab ntes muaj lub tswb ceeb toom tshaj qhov txwv; yog tias cov ntaub ntawv sau tau tshaj qhov txwv, lub cuab yeej tam sim ntawd ua rau muaj kev co thiab lub tswb suab-pom, xa cov ntaub ntawv tam sim no mus rau lub platform.
COV NTAUB NTAWV KHOOM
1. Kev kuaj pom roj siab: Cov neeg ua haujlwm hauv thaj chaw uas nqa lub cuab yeej tuaj yeem txiav txim siab seb qhov chaw ib puag ncig puas muaj kev nyab xeeb lossis tsis raws li cov ntaub ntawv qhia txog cov roj uas lub cuab yeej tso tawm, yog li ntawd thiaj li lav qhov kev nyab xeeb ntawm lub neej thiab khoom ntawm cov neeg ua haujlwm.
2. Tshaj qhov txwv suab thiab lub teeb ceeb toom: Thaum lub cuab yeej pom tias cov roj ib puag ncig tshaj qhov tus qauv, nws yuav tam sim ntawd tso tawm lub suab thiab lub teeb ceeb toom kom ceeb toom cov neeg ua haujlwm hauv thaj teb kom khiav tawm raws sijhawm
3.4G kis thiab GPS qhov chaw: cov ntaub ntawv roj sau thiab GPS qhov chaw raug xa mus rau PC terminal rau kev saib xyuas lub sijhawm tiag tiag ntawm qhov chaw
COV KHOOM TXHEEJ TXHEEM
◆ Chav kawm tiv thaiv: IP67
◆ Hom qhia: LCD tso saib cov ntaub ntawv tiag tiag thiab qhov xwm txheej ntawm lub cev, lub suab co thiab lub teeb ceeb toom, qhov txhaum thiab qhov tsis muaj zog
◆ ntsuas ntau yam:
Alkanes (CH₄): 0-4% (VOL) lossis 0-100% (LEL) Kev daws teeb meem: 0.01%
