1. Introduction
Portable Digital Refractometers are microprocessor-based with laboratory accuracy to be able to accurately and instantly
measure the refractive index(RI) , concentration and other parameters for many kinds of liquids, which also have a friendly
operation pattern and display field as well as an automatically temperature compensation system, including 6 series and
12models , comparing with the traditional hand held ones they are much faster, more accurately, and clearly in measurements, as
