Technical tej yam kev mob ntawm illuminance meter ntsuas
Koj puas siv koj qhov kev xav los txiav txim qhov ci ntawm lub teeb? Los yog siv tib txoj kev los txiav txim seb qhov twg ntawm cov khoom zoo sib xws yog ci dua? Koj puas paub tias qhov sib txawv loj npaum li cas? Kuv xav tias txhua tus neeg yuav tsum txhawj xeeb heev txog seb qhov kev faib tawm ntawm lub teeb ntawm lub teeb puas zoo ib yam li tus qauv tsim. Raws li ib tug pioneer hauv kev lag luam teeb pom kev zoo, koj thiab kuv yuav tsum tau siv cov cuab yeej teeb pom kev zoo - lub ntsuas hluav taws xob. Tau ntsib nrog ntau lub npe sib txawv ntawm cov ntsuas hluav taws xob, qhov sib txawv ntawm lawv qhov zoo thiab tus nqi kuj yog qhov dav heev. Yuav ua li cas xaiv qhov tsim nyog yog feem ntau nerve-wracking. Ntawm no yog ib qho yooj yim piav qhia:
Ib qho zoo tagnrho illuminance meter yuav tsum muaj cov hauv qab no:
● Compact Size, Lub teeb yuag
Lub illuminance meter muaj ntau yam kev siv, thiab lub sij hawm siv feem ntau nyob rau hauv ntau qhov chaw. Yog li ntawd, qhov loj me me, me me thiab lub teeb yuag yog qhov yuav tsum tau ua ua ntej rau lub ntsuas hluav taws xob.
● Qhov tseeb?Qhov tseeb?
Txawm hais tias lub teeb meter yog qhov zoo lossis qhov tsis zoo muaj kev sib raug zoo nrog nws qhov tseeb. Ntawm chav kawm, nws kuj yog ze ze rau nws tus nqi. Yog li ntawd, nws yog ib qho tsim nyog yuav tau yuav lub ntsuas hluav taws xob siab kom raug ntawm tus nqi tsim nyog. Feem ntau, nws yog qhov tsim nyog kom muaj qhov yuam kev tsis ntau tshaj ± 15%.
● Xim Xaus ?Cov Xim Xim?
Cov hom teeb pom kev zoo yog tag nrho-encompassing. Qee qhov tsom mus rau cov teeb liab siab siab nrog lub teeb ntev dua, lossis cov teeb xiav-violet nrog luv luv wavelengths xws li Daylight fluorescent teeb. Kuj tseem muaj qhov sib npaug sib npaug xws li cov qij taws teeb. Tib lub illuminance meter yuav muaj qhov sib txawv me ntsis rau qhov sib txawv wavelengths. sib txawv, yog li tsim nyog them nyiaj.
●Cosine Compensation?Cosine Compensation?
Raws li peb txhua tus paub, qhov ci ntsa iab ntawm qhov illuminated nto yog cuam tshuam nrog qhov xwm txheej ntawm lub teeb ci. Nyob rau hauv tib txoj kev, thaum ntsuas nrog lub teeb meter, qhov xwm txheej lub kaum sab xis ntawm lub sensor thiab lub teeb qhov chaw yuav cuam tshuam rau kev nyeem ntawv ntawm lub teeb ntsuas. Yog li ntawd, seb lub ntsuas hluav taws xob zoo puas muaj lub luag haujlwm ntawm cosine them nyiaj tsis tuaj yeem tsis quav ntsej.
