Refractometer, tseem hu ua refractometer, yog ib qho cuab yeej siv lub teeb los ntsuas qhov concentration ntawm cov kua. Nws yog siv los ntsuas qhov refractive index, birefringence, thiab optical zog. Lub refractive index yog ib qho tseem ceeb ntawm lub cev tsis tu ncua ntawm cov khoom. Lub digital refractometer tuaj yeem sau cov teeb liab, hloov ntau yam kev hloov pauv rau hauv cov teeb liab hluav taws xob hloov pauv, thiab nthuav dav cov cim sau. coj cov teeb liab. Kev txiav txim siab tso saib Circuit Court hloov cov teeb liab digital mus rau hauv lub teeb liab uas cov zaub tuaj yeem paub, thiab txuas nrog rau cov duab digital.
Kev ceev faj rau kev siv yog raws li nram no:
1. Tsis txhob tso cov cuab yeej no mus rau qhov kub thiab txias, qhov kub thiab txias ib puag ncig, tiv thaiv cov kua siv lead ua kua los ntawm kev poob nws txoj haujlwm, thiab txwv tsis pub muaj kev sib tsoo.
2. Txhawm rau tiv thaiv nws qhov kev puas tsuaj, thov tsis txhob disassemble lossis hloov nws cov khoom siv sab hauv ntawm lub siab nyiam, thiab thov tsis txhob siv cov cuab yeej no hauv qhov chaw ntub thiab corrosive.
3. Ntxuav lub ntsej muag prism thiab prism lub qhov rais ua ntej thiab tom qab txhua qhov ntsuas.
4. Txhawm rau tiv thaiv qhov cuam tshuam ntawm kev ntsuas qhov tshwm sim vim yog cov tshuaj volatilization, thov ntsuas tam sim tom qab cov tshuaj yog dripped.
5. Yog tias qhov hluav taws xob tsis txaus, qhov ntsuas qhov ntsuas yuav raug cuam tshuam.
6. Tiv thaiv kom tsis txhob muaj kua nkag mus rau hauv cov ntaub ntawv roj teeb.
