A. Product Overview
The R-Tek RK-401 Digital Refractometer is designed for quick and accurate measurement of Brix values in liquids and solutions. Brix measurement is commonly used to evaluate sugar concentration and dissolved solids in products such as fruit juices, beverages, syrups and other liquid samples.
The RK-401 provides a 0.0 to 55 percent Brix range and requires only a small sample of more than 0.2 ml, approximately 3 to 5 drops, making routine testing convenient.

B. Working Principle
A digital refractometer determines the concentration of a liquid by measuring how light behaves when it passes through or interacts with the sample.
A few drops of the liquid sample are placed on the measuring surface. The refractometer's optical system analyzes the refractive characteristics of the sample and electronically converts the measurement into a Brix value displayed on the digital screen.
In simple terms:
Liquid sample → Optical measurement → Refractive index analysis → Digital Brix reading
For the RK-401, IndustryBuying also describes an advanced optical measurement system and digital display for concentration testing.
The instrument includes automatic environmental compensation, which helps compensate for environmental and temperature related effects during measurement.
