Kev ruaj ntseg zoo thiab kev nyab xeeb hauv kev tsim khoom
Nyob rau hauv lub chaw tsim khoom rhiav, machinery thiab khoom roar ib hnub thiab hmo ntuj. Cov suab nrov dhau lawm tsis yog cuam tshuam rau kev sib txuas lus thiab kev sib koom tes ntawm cov neeg ua haujlwm, tab sis ntev - raug cuam tshuam los kuj tuaj yeem ua rau lawv qhov hnov lus zoo. Lub Huashengchang DT-3852 kev ntsuas suab nrov muaj qhov zoo ntawm kev ntsuas qhov siab, uas tuaj yeem ntsuas qhov decibel suab nrov tsim los ntawm ntau qhov chaw thiab cov khoom siv hauv kev cob qhia hauv lub sijhawm thiab raug.
Qhov ntau yam tsis siv neeg ntawm lub ntsuas suab nrov no yog 30dB txog 130dB, npog qhov ntsuas ntau los ntawm qhov ntsiag to mus rau qhov siab decibel nrov. Qhov qis qis yog 30dB txog 80dB, qhov nruab nrab yog 50dB txog 100dB, thiab qhov siab yog 80dB txog 130dB. Tsis hais txog qib ntawm cov khoom siv suab nrov, nws tuaj yeem ntsuas qhov tseeb. Nws qhov kev daws teeb meem tuaj yeem ncav cuag 0.1dB, thiab txawm tias qhov hloov pauv hloov suab nrov tuaj yeem raug ntes tau.
Thaum lub suab nrov txawv txav los ntawm kev hnav thiab tsim kua muag ntawm cov khoom siv lossis lwm yam laj thawj, DT-3852 lub suab nrov tuaj yeem hloov kho lub suab nrov ntawm qhov sib txawv ntawm qhov sib txawv nrog nws lub sijhawm ceev ntawm 125 milliseconds thiab lub sij hawm qeeb ntawm qhov hnyav ntawm 1 thib ob, thiab kuaj cov suab nrov tsis raws sijhawm.
Nyob rau tib lub sijhawm, nws kuj ua raws li IEC61672-1 Qib 2 tus qauv, kom ntseeg tau qhov tseeb thiab kev ntseeg siab ntawm kev ntsuas, thiab muab kev tshawb fawb hauv paus rau kev tu thiab kho cov khoom siv.
Kev nkag siab txog Kev Ua Phem Tsis Zoo hauv Kev Saib Xyuas Ib puag ncig 02
Qhov teeb meem ntawm lub suab nrov hauv ib puag ncig hauv nroog tau txais kev saib xyuas ntxiv. Cov tsheb khiav tas mus li ntawm cov hlab ntsha ntawm cov hlab ntsha thiab kev tsim kho ntawm cov chaw tsim kho tuaj yeem dhau los ua cov pa phem. Lub Hushengchang DT-3852 kev ntsuas suab nrov ua lub luag haujlwm tseem ceeb hauv kev saib xyuas ib puag ncig.
Nws ultra ci backlit loj screen LCD zaub muaj nuj nqi tso cai rau ib puag ncig tiv thaiv cov neeg ua haujlwm los nyeem cov ntaub ntawv ntsuas kom meej nyob rau hauv ntau yam teeb pom kev zoo. Lub ntsuas suab nrov muaj qhov tsim ua -hauv USB interface, txhawb nqa cov ntaub ntawv xa mus thiab khaws cia, thiab tuaj yeem sau 32700 cov ntaub ntawv, ua kom yooj yim rau cov neeg ua haujlwm txhawm rau txheeb xyuas thiab ua cov ntaub ntawv ntsuas.
Cov neeg ua haujlwm nqa DT-3852 thiab thauj mus los ntawm txoj kev, txoj kev, thiab cov chaw tsim kho hauv nroog. Hauv cov chaw tsheb tsis khoom, lawv tuaj yeem ntes cov suab nrov nrov uas tsim los ntawm kev tsav tsheb, honking, thiab lwm yam. Qhov siab tshaj plaws thiab qhov tsawg kawg nkaus tuaj yeem ntsuas tam sim ntawd txhawm rau ntes thiab pom lub suab nrov nrov, pab txheeb xyuas cov suab nrov nrov xws li tsheb honking, suab nrov kho kom zoo nkauj, thiab lwm yam, thiab muab cov ntaub ntawv txhawb nqa rau cov chaw tswj xyuas kev tsheb khiav kom zoo, teeb tsa tsis muaj honking thaj chaw, thiab lwm yam.
Nyob rau ntawm qhov chaw tsim kho, nws tuaj yeem saib xyuas hauv lub sijhawm tiag tiag - seb lub suab nrov thaum lub sijhawm tsim kho dua tus qauv. Nws txoj haujlwm hloov pauv A / C tuaj yeem xaiv tau raws li qhov xav tau ntawm kev ntsuas sib txawv, ua tau raws li cov kev cai ntawm kev ntsuas suab nrov thiab kev tshuaj xyuas hauv ntau qhov chaw. Nws saib xyuas cov tsev tsim kho kom txo cov suab nrov, xws li siv cov khoom siv suab nrov tsawg - thiab teem sijhawm tsim kho kom tsim nyog, txo qhov cuam tshuam rau lub neej ntawm cov neeg nyob ib puag ncig.
03 Tus Tsim Nyog Ntawm Qhov Chaw Nyob Sab Hauv Tsev
Ib puag ncig zoo nkauj yog qhov tseem ceeb rau tib neeg txoj haujlwm, kawm, thiab so hauv tsev xws li chaw ua haujlwm, tsev kawm ntawv, thiab tsev so. Huashengchang DT-3852 kev ntsuas suab nrov tuaj yeem pab tsim kom muaj suab nrov sab hauv tsev.
