Kev ntsuas cov qauv thiab hom illuminance meters
Lub lux meter, tseem hu ua lux meter, yog ib qho cuab yeej tshwj xeeb rau kev ntsuas qhov pom kev. Nws yog ntsuas qhov degree uas ib qho khoom illuminated, uas yog, qhov piv ntawm cov luminous flux tau nyob rau saum npoo ntawm cov khoom mus rau qhov chaw illuminated. Lub ntsuas hluav taws xob feem ntau yog tsim los ntawm selenium lossis silicon photovoltaic cell, lim, thiab microampere meter.
1. Taug qab thiab sau cov kev hloov pauv hauv kev teeb pom kev zoo thoob plaws tag nrho cov txheej txheem, nrog lub sijhawm kaw ntev (cov ntaub ntawv kaw txhua txhua 15 feeb ntev txog 5 lub hlis lossis ntev dua), kev sib koom ua ke cov ntaub ntawv sau, kaw, thiab xa tawm.
2. Lub tshuab tag nrho muaj kev siv hluav taws xob tsawg thiab yog siv los ntawm lithium roj teeb (built-in), nrog lub roj teeb lub neej ntev tshaj li ib xyoos.
3. Lub software muaj ob versions, Suav thiab Askiv, uas tuaj yeem xaiv tau dawb. Cov lus Askiv version muaj thoob ntiaj teb universality.
4. Lub software muaj zog ua haujlwm thiab yooj yim saib cov ntaub ntawv.
5. Tsis siv neeg tsim cov ntaub ntawv nkhaus, thiab cov ntaub ntawv khaws cia tuaj yeem ua tiav siv EXCEL, WORD, lossis software.
6. Lub sijhawm kaw lub sijhawm tuaj yeem teeb tsa arbitrarily ntawm 2 vib nas this mus rau 24 teev.
7. Qhov loj me (58 × 72 × 29mm), ua haujlwm yooj yim, txhim khu kev qha kev ua tau zoo (tsim rau qhov chaw hnyav, tsis muaj ntaub ntawv poob thaum lub zog tsis ua haujlwm).
8. Nws tuaj yeem ua lub tswb nrov.
Daim ntawv thov Scope
1. Daim ntawv thov nyob rau hauv cov chaw pej xeem
Txhawm rau kom ntseeg tau tias tib neeg tuaj yeem nyob rau hauv cov teeb pom kev zoo tsim nyog, Tuam Tshoj tau tsim cov qauv kev nyiam huv rau sab hauv tsev (nrog rau cov chaw pej xeem) illuminance, thiab siv cov illuminance meters ntsuas illuminance nyob rau hauv ntau qhov chaw.
2. Kev lag luam teeb pom kev zoo, kev lag luam yees duab, theem teeb pom kev zoo, thiab lwm yam
Illuminance meters tau ua tiav rau ntau yam kev daws teeb meem, xws li kev lag luam teeb pom kev zoo, kev lag luam yees duab, theem teeb pom kev zoo, thiab lwm yam. Cov qauv sib txawv ntawm cov illuminance meters tuaj yeem ua tau raws li cov kev ntsuas sib txawv.
3. Daim ntawv thov ntawm lub Hoobkas ntau lawm kab
Hauv cov chaw tsim khoom thiab cov kab ntau lawm, cov teeb pom kev zoo yuav tsum nruj heev. Kev ua haujlwm tsis tu ncua tuaj yeem ua rau pom kev qaug zog thiab txo qis kev ua haujlwm zoo. Feem ntau, qhov yuav tsum tau illuminance ntau dua los yog sib npaug rau 1000Lx. Rau qhov chaw uas muaj teeb pom kev zoo siab, muaj ntau yam illuminance meter tuaj yeem xaiv tau, nrog rau ntau qhov loj loj uas tuaj yeem tiv nrog kev ntsuas lub teeb pom kev zoo.
