Automatic Refractometer/ Refractometer With High Measuring Resolution//Refractometer refractive index

Brief Introduction

LR-R?is equipped with a high performance linear CCD sensor. Through high-speed and high precision signal acquisition, analysis and processing technology, the LR-J-R is equipped with a semiconductor Parte super temperature control system. It can measure the refractive index (Nd) and the mass fraction of sugar solution (Brix) of transparent, translucent, dark and viscous liquid with high accuracy and efficiency.
