Resolution 0.00001 Fully Automatic Refractometer Scope 1.30000--1.70000ND 32GB

Product Specification

ST-138C Fully automatic refractometer

The ST-138C fully automatic refractometer (refractometer) is equipped with high-performance linear CCD photosensitive components, and is equipped with a semiconductor Peltier super temperature control system through high-speed and high-precision signal acquisition and analysis processing technology. It can efficiently and accurately measure the refractive index (nD) of various liquids such as transparent, semi transparent, dark, and viscous, as well as the mass fraction (Brix) of sugar solutions.

Determination of refractive index in accordance with General Rule 0622 of the 2025 edition of the Chinese Pharmacopoeia and determination of refractive index in accordance with GB 15680-2009 palm oil, GB1535 soybean oil, GB/T 1536-2021 rapeseed oil, GB/T8233-2018 sesame oil, GB/T 23347-2021 olive oil, GB/T 19111-2017 corn oil, GB/T22479 Sichuan pepper seed oil and other edible oils. The fully automatic refractometer has a wide range of applications in the oil and fat industry, pharmaceutical industry, food industry, daily chemical industry, sugar industry, etc. It is also one of the commonly used equipment in schools and related research institutions.
