Phau Ntawv Paub Txog UV Illuminance Meters
Txheej txheem cej luam ntawm UV illuminance meter
UV illuminance meter, tseem hu ua UV irradiance meter, UV siv meter, thiab lwm yam, nws tsuas yog ntsuas qhov kev siv ntawm ultraviolet hluav taws xob, siv nyob rau hauv photochemistry, polymer cov ntaub ntawv aging, flaw detection, UV teeb qhov chaw, cog cultivation, loj-scale integrated circuits. photolithography thiab lwm yam haujlwm ntawm UV hluav taws xob ntsuas kev ua haujlwm.
Lub UV illuminometer siv 35 cov khoom sib txawv los ntsuas UVA, UVB, UVC, pom lub teeb thiab lub teeb infrared. Kev ntsuas wavelength ntawm UV illuminance meter muab faib ua UVA (320nm-380}nm), UVB (280nm-320}nm), UVC (200nm-280}nm), thiab qee yam khoom tuaj yeem ntes tau dav. ntau yam ntawm wavelengths, cov neeg siv-phooj ywg ua haujlwm, compact thiab saj zawg zog, tuaj yeem ua haujlwm los ntawm ib sab tes, kev sojntsuam yog cais tawm ntawm lub cev, yooj yim thiab yooj yim, thiab ntau lub cim xeeb tsis siv neeg, tuaj yeem khaws 20 pawg ntawm cov ntaub ntawv, tuaj yeem siv dav hauv Kev noj qab haus huv, kev kho mob, tshuaj lom neeg, kev huv huv, khoom noj khoom haus, hluav taws xob, aerospace thiab lwm yam lag luam, haum rau UV, kev kho lub cev, kev tsom xam fluorescence, UV lithography, kev kho dej, kev yug me nyuam thiab lwm yam kev ntsuas UV irradiance.
Lub hauv paus ntsiab lus ntawm UV illuminance meter
UV illuminance meter yog qhov ntsuas tshwj xeeb ntawm luminosity, ci ntsa iab ntawm qhov ntsuas. Nws yog los ntsuas qhov siv ntawm lub teeb (illuminance) yog qhov ntsuas ntawm qhov pom ntawm qhov khoom, uas yog, qhov sib piv ntawm cov luminous flux tau txais los ntawm qhov chaw ntawm qhov khoom mus rau thaj chaw illuminated. Illuminance meter feem ntau yog tsim los ntawm selenium photocell lossis silicon photocell thiab microampere meter. Lub hauv paus ntsiab lus yog: photocell yog cov khoom siv hluav taws xob uas hloov lub teeb hluav taws xob ncaj qha rau hauv hluav taws xob hluav taws xob. Thaum lub teeb raug coj mus rau saum npoo ntawm selenium photovoltaic cell, qhov teeb meem tshwm sim mus txog qhov sib faib ntawm cov semiconductor selenium txheej 2 thiab cov yeeb yaj kiab hlau 4 los ntawm cov yeeb yaj kiab hlau 4, thiab tsim cov nyhuv photoelectric ntawm lub interface. Qhov loj ntawm lub peev xwm sib txawv generated yog proportional rau lub illuminance ntawm lub teeb-tau txais nto ntawm lub photocell. Hauv qhov no, yog tias ib qho kev sib txuas sab nraud txuas nrog, qhov tam sim no dhau mus, thiab tus nqi ntawm qhov tam sim no qhia los ntawm microampere meter kawm tiav hauv lux (Lx). Qhov loj ntawm photocurrent nyob ntawm qhov siv ntawm qhov teeb meem teeb meem thiab qhov tsis kam nyob rau hauv Circuit Court. Lub illuminance meter muaj ib tug sib txawv gearing ntaus ntawv, thiaj li hais tias nws muaj peev xwm ntsuas siab illuminance thiab tsawg illuminance.
