Dab tsi yog qhov infrared thev naus laus zis ntawm portable infrared thermometers?
Infrared tshuab rau portable infrared ntsuas kub;
Ib qho kev nkag siab tsis pom zoo ntawm nws cov ntsiab lus thiab nws qhov ntsuas kub. Thaum ntsuas qhov ntsuas kub ntawm lub ntsuas kub infrared, lub zog infrared tso tawm los ntawm cov khoom ntsuas tau hloov mus rau hauv lub teeb liab hluav taws xob ntawm lub ntsuas hluav taws xob los ntawm kev kho qhov muag ntawm lub ntsuas kub infrared. Qhov ntsuas kub nyeem ntawm lub teeb liab tau tshwm sim. Ntau yam txiav txim siab qhov tseeb ntawm qhov ntsuas. Qhov kub thiab txias yog qhov tseem ceeb, qhov tseem ceeb tshaj plaws yog emissivity, thaj chaw ntawm kev pom, qhov deb ntawm qhov chaw thiab qhov chaw ntawm qhov chaw. Emissivity, tag nrho cov khoom yuav xav txog, xa thiab emit zog, thiab tsuas yog lub emission zog yuav qhia tau qhov kub ntawm cov khoom.
Portable infrared ntsuas kub tau txais tag nrho peb hom zog thaum lawv ntsuas qhov kub thiab txias. Yog li ntawd, tag nrho cov ntsuas kub infrared yuav tsum tau kho kom nyeem tsuas yog lub zog emission. Kev ntsuas qhov yuam kev feem ntau tshwm sim los ntawm lub zog infrared cuam tshuam los ntawm lwm qhov chaw teeb pom kev zoo. Qee qhov ntsuas kub infrared tuaj yeem sib txawv ntawm emissivity, thiab emissivity qhov tseem ceeb rau ntau yam ntaub ntawv tuaj yeem pom hauv cov ntawv luam tawm emissivity. Lwm cov twj paj nruag muaj qhov ruaj emissivity preset ntawm 0.95. Tus nqi emissivity no yog qhov kub thiab txias ntawm cov khoom siv organic feem ntau, xim lossis oxidized nto thiab yuav tsum tau them nyiaj los ntawm kev siv daim kab xev los yog cov xim dub tiaj tus rau saum npoo raug ntsuas.
Thaum cov ntaub nplaum los yog xim pleev xim rau qhov kub thiab txias tib yam li cov khoom siv hauv paus, ntsuas qhov kub thiab txias ntawm daim kab xev los yog xim xim los txiav txim seb nws qhov kub thiab txias. Qhov ratio ntawm qhov deb mus rau lub teeb qhov chaw. Lub tshuab kho qhov muag ntawm tus pas ntsuas kub infrared sau lub zog los ntawm lub voj voog ntsuas qhov chaw thiab tsom nws ntawm lub ntsuas. Qhov kev daws teeb meem kho qhov muag tau txhais raws li qhov piv ntawm qhov kev ncua deb ntawm lub ntsuas kub infrared mus rau qhov khoom thiab qhov loj ntawm qhov ntsuas qhov pom kev (D :S). Qhov loj dua qhov sib piv, qhov zoo dua qhov kev daws teeb meem ntawm tus pas ntsuas kub infrared thiab qhov me me ntawm qhov ntsuas qhov loj me. Laser aiming tsuas yog siv los pab txhawm rau ntsuas qhov ntsuas. Qhov kev txhim kho tshiab tshaj plaws hauv infrared optics yog qhov sib ntxiv ntawm qhov ua kom pom tseeb, uas muab qhov ntsuas qhov tseeb ntawm cov phiaj xwm me me thiab tseem tiv thaiv qhov cuam tshuam ntawm qhov kub thiab txias.
Field of view, xyuas kom meej tias lub hom phiaj loj dua qhov chaw loj ntawm lub ntsuas kub infrared thaum ntsuas. Lub hom phiaj me dua, qhov ze koj yuav tsum tau mus rau nws. Thaum qhov tseeb yog qhov tseem ceeb tshwj xeeb, xyuas kom lub hom phiaj yog tsawg kawg 2 zaug ntawm qhov chaw loj.
