Ua hauj lwm hauv paus ntsiab lus ntawm online refractometer
Refractive index (tseem hu ua refractive index, refractive index RI) yog lub cev tsis tu ncua ntawm ib yam khoom. Cov khoom ntshiab ntawm cov khoom khib nyiab, kua thiab cov pa roj muaj ib qho kev ntsuas refractive.
Rau cov kua sib xyaw ua ke, thaum lub teeb dhau los ntawm cov kua ntawm qhov sib txawv, nws yuav tsim qhov sib txawv refractive indexes. Qhov siab dua qhov concentration, qhov ntau dua qhov refractive index. Raws li txoj cai hloov pauv ntawm "kev daws teeb meem refractive index - solute concentration" (20 degree), koj tuaj yeem siv A refractometer yooj yim ntsuas qhov concentration ntawm cov kua.
Refractive index yog ib qho khoom tshwj xeeb ntawm cov khoom. thiab hloov pauv nyob ntawm qhov kub thiab qhov ntev. Yog li ntawd, nrog ib tug refractometer, thaum lub ntsuas kub thiab wavelength paub, lub concentration ntawm cov kua yuav raug kuaj pom los ntawm kev kuaj lub refractive index. Tau kawg, cov khoom sib txawv yuav muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv.
Yog li ntawd, kev soj ntsuam kom pom tseeb raws li qhov ntsuas qhov ntsuas pom yuav tsum nyob ze li sai tau rau cov khoom sib xyaw binary (kua uas muaj ob yam khoom). Tau kawg, hauv kev siv tswv yim, yog tias qhov kev hloov pauv ntawm ntau lub ntsiab lus daws teeb meem (cov kua muaj ntau yam khoom siv) tsuas yog tshwm sim los ntawm kev hloov ntawm ib qho ntawm cov khoom, nws tuaj yeem ntsuas qhov tseeb los ntawm kev ntsuas qhov ntsuas qhov ntsuas. Qhov no kuj yog ib qho kev ntsuas quantitative. Cov kua dej sib xyaw ntawm cov khoom sib xyaw uas paub zoo tuaj yeem kuaj xyuas kom zoo. Piv txwv li, rau cov khoom sib tov xws li txiv roj roj lossis kua txiv kab ntxwv, qhov ntsuas tus nqi tau lees tias nyob rau hauv ib qho kev sib tw, uas tuaj yeem ua kom cov khoom zoo.
Online refractometer qauv thiab muaj nuj nqi
Lub refractometer online txais kev sib cais tsim qauv thiab muab faib ua ob ntu: sensor thiab transmitter.
Sensor: muaj li ntawm sapphire prism (9Mosh), built-in PT1000 kub sensor, lub neej ntev LED teeb qhov chaw 100000h, CCD sensor nrog 3648 pixel daws teeb meem;
Transmitter: Intel 586sx 133MHz CPU, 6.7 "(640 × 480 pixels) TFT-LCD zaub, keyboard, EPROM nco daim npav thiab tsis siv neeg tu system. Cov cuab yeej siv lub zog tiv thaiv kev cuam tshuam, siab kub thiab kev co kuj, ntau yam, Hoobkas linear calibration thiab tsis siv neeg qhov kub thiab txias qhov ntsuas ntsuas ua haujlwm nrog tus phooj ywg software Nws muaj qhov ntsuas kub ua kom pom cov txheej txheem kub ntawm cov kua protein hauv online thiab lub teeb liab ntawm 0-10V. 9}} txhawm rau sib txuas lus nrog lub tshuab computer thiab tuaj yeem sib txuas lus nrog DCS los ntawm 4 ~ 20 mA teeb liab DCS tswj thiab tswj cov concentration ntawm cov txheej txheem tshuaj.
