Dab tsi yog qhov kev sib raug zoo ntawm cov khoom siv roj thiab cov pa phem?
Gas detector yog ib qho cuab yeej cuab tam rau kev tshawb nrhiav roj to concentration, xws li portable gas detectors, handheld gas detectors, fixed gas detectors, online gas detectors, etc. Gas sensors yog siv los txheeb xyuas ntau yam gases hauv ib puag ncig. Gas sensors yog siv los xyuas qhov muaj pes tsawg leeg thiab cov ntsiab lus ntawm cov pa roj.
Yuav xaiv lub ntsuas roj li cas?
Ua ntej ntawm tag nrho cov, nws nyob ntawm seb lub combustible gas detector muaj stability. Qhov me dua qhov xoom offset thiab tag nrho amplitude offset qhov tseem ceeb, qhov zoo dua. Txhua lub tshuab kuaj pom roj muaj qhov cuam tshuam ntau dua lossis tsawg dua rau lwm cov pa tshwj tsis yog oxygen. Qhov ntau tshaj plaws yog electrochemical sensors uas ntes hydrogen sulfide. Yog li ntawd, raws li cov neeg siv, peb yuav tsum paub txog cov pa phem uas muaj nyob hauv peb lub tsev.
Qhov thib ob, ua tib zoo saib seb lub ntsuas hluav taws xob puas yog qhov yooj yim los txheeb xyuas. Digital lossis pointer gas detectors. Feem ntau, cov qauv lej muaj qhov zoo ntawm kev nyeem tau zoo thiab kev txiav txim siab tsawg dua. Txawm hais tias thaj chaw tso saib loj txaus, nrog backlighting thiab loj fonts kom yooj yim nyeem thiab nkag siab.
Puas yog lub tswb nrov txaus kom paub qhov txawv ntawm lub suab nrov tom qab? Lub tswb flash puas tuaj yeem txheeb xyuas los ntawm ntau lub kaum ntse ntse? Nrog rau kev hloov pauv ntawm qhov ntsuas roj concentration, seb lub teeb liab tuaj yeem tshwm sim tsis tu ncua, thiab lub tswb yuav tsum tau nres tom qab kev pom zoo lossis kev ntsuas.
Tom qab ntawd xyuam xim rau lub neej ntawm lub sensor, ntev dua qhov zoo dua. Feem ntau, qhov nruab nrab lub neej ntawm cov khoom siv hluav taws xob hluav taws xob yog 2-5 xyoo, thiab qhov yuam kev me me, qhov zoo dua. Qhov tseeb thiab qhov tseeb nce ntxiv ntawm kev pabcuam lub neej. Cov khoom warranty lub sij hawm yog feem ntau 2 xyoo.
Thaum kawg, xyuas tias cov khoom siv hluav taws xob uas siv tau yooj yim. Lub tshuab hluav taws xob zoo hluav taws xob muaj cov yam ntxwv hauv qab no: lub teeb yuag, me me, hnav yooj yim thiab xis nyob, thiab yooj yim los tswj.
Kev sib raug zoo ntawm cov khoom siv roj thiab cov pa phem
Kev tswj cov pa phem, saib xyuas ua ntej. Hauv cov txheej txheem ntawm kev tswj hwm huab cua, cov khoom siv roj tuaj yeem "kuaj qhov txaus ntshai" rau tib neeg thiab ua siab ntev nrog cov pa phem, tsim kev puas tsuaj, tawg thiab tawg. Gas detectors tuaj yeem tso cai rau tib neeg kom nkag siab zoo dua cov ntsiab lus ntawm ntau yam roj cua hauv huab cua, thiab pab txhawb kev taug qab qhov chaw ntawm cov pa phem. Nyob rau hauv cov txheej txheem ntawm kev ua haujlwm ntawm lub Hoobkas, lub tshuab ntsuas roj tuaj yeem saib xyuas cov pa tawm ntawm cov pa phem thiab cov pa phem txhua lub sijhawm, nip ntau lawm kev nyab xeeb kev nyab xeeb nyob rau hauv lub paj, thiab tseem saib xyuas seb cov pa tso pa tawm hauv kev ua txhaum cai.
