Lub ntsuas cua sov infrared CH4 GJH4(A)
Daim Ntawv Thov:
GJH4 (A) Infrared CH4 Meter tuaj yeem hloov pauv qhov CH4 concentration mus rau hauv lub teeb liab hluav taws xob thiab tom qab ntawd xa mus rau cov khoom siv sib phim. Nws tuaj yeem qhia qhov concentration ntawm methane hauv situ thiab nws muaj lub luag haujlwm ntawm transfinite audible thiab visual alarm. Nws tuaj yeem txuas nrog lub kaw lus saib xyuas, breaker thiab cua zog roj xauv cov cuab yeej. Nws yog dav siv hauv kev ua haujlwm thee mining, hluav taws xob thiab tshuab qhov tsua thiab rov qab los ntawm huab cua.
Qhov Tseem Ceeb:
1. Nws siv hom tshiab ib leeg microcomputer thiab high integration digital circuit. Ces lub circuit qauv yooj yim. Kev ua tau zoo yog txhim khu kev qha. Yooj yim rau kev txij nkawm thiab debugging.
2. Nws muaj qhov ua haujlwm ntawm Infrared chaw taws teeb calibration xoom, rhiab heev thiab ceeb toom thaum muaj xwm ceev. Nws yooj yim thiab yooj yim rau calibrating.
3. Lub sensor muaj kev tswj hwm ntxiv. Koj tuaj yeem teeb tsa qhov txiav tawm raws li koj xav tau. Nws muaj ntau yam kev siv.
4. Siv hom fais fab hloov tshiab, txo qhov siv hluav taws xob ntawm lub cav, ua kom qhov nrug ntawm qhov ntsuas nce ntxiv.
5. Kev ua haujlwm ntawm tus kheej, yooj yim siv thiab tswj.
6. Lub plhaub tshiab muaj zog heev, txhim kho qhov cuam tshuam ntawm cov cuab yeej.
