Qhov txawv ntawm tes tuav qab zib ntsuas thiab tes tuav refractometer
1. Handheld qab zib meter:
Lub ntsuas hluav taws xob tuav tes yog siv los txiav txim siab yooj yim thiab nrawm ntawm qhov hnyav feem pua ntawm cov ntsiab lus lossis qhov ntsuas qhov ntsuas pom hauv cov ntsiab lus qab zib. Siv dav hauv qab zib, zaub mov, dej haus thiab lwm yam kev lag luam, nrog rau kev ua liaj ua teb thiab kev tshawb fawb tshawb fawb.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm: Lub ntsuas suab thaj feem ntau yog siv qhov tshwm sim ntawm qhov tshwm sim thaum lub teeb nkag mus rau lwm qhov nruab nrab ntawm ib qho nruab nrab, thiab qhov sib piv ntawm sine ntawm lub kaum sab xis ntawm qhov xwm txheej yog qhov tsis tu ncua, thiab qhov piv no yog hu ua refractive index. Lub refractive Performance index ntawm cov kua qab zib tuaj yeem ntsuas tau los ntawm kev siv qhov sib piv ncaj qha ntawm cov ntsiab lus ntawm cov tshuaj soluble hauv cov kua qab zib thiab cov refractive index nyob rau hauv cov xwm txheej zoo tib yam, kom cov piam thaj concentration tuaj yeem xam los ntawm cov ntsuas qab zib / refractometer.
2. Handheld refractometer
Lub tes tuav refractometer yog ib qho cuab yeej uas tuaj yeem ntsuas qhov ntsuas qhov cuam tshuam nD thiab qhov nruab nrab dispersion nF-nC ntawm pob tshab, cov kua nplaum lossis cov khoom khib nyiab (tsuas yog rau cov kua pob tshab). Yog tias lub ntsuas ntsuas txuas nrog lub ntsuas kub, nws tuaj yeem ntsuas qhov ntsuas qhov ntsuas qhov ntsuas ND hauv qhov ntsuas kub ntawm 0 ~ 70. Refractive index thiab nruab nrab dispersion yog ib qho tseem ceeb ntawm cov khoom siv kho qhov muag, uas tuaj yeem siv los nkag siab txog cov khoom siv kho qhov muag, purity, concentration thiab dispersion ntawm cov khoom. Cov cuab yeej tseem tuaj yeem ntsuas qhov feem pua ntawm cov piam thaj hauv cov tshuaj sucrose. Yog li, cov cuab yeej no muaj ntau yam kev siv, thiab yog ib qho tseem ceeb ntawm cov cuab yeej siv rau cov chaw tsim khoom, cov tsev kawm ntawv thiab cov chaw tshawb fawb xws li kev lag luam roj av, kev lag luam roj, kev lag luam pleev xim, kev lag luam khoom noj, kev lag luam tshuaj txhua hnub, kev lag luam qab zib thiab kev soj ntsuam geological.
