WYA-2S Digital Abbe Refractometer
Product Introduction
The
WYA-2S Digital Abbe Refractometer is a laboratory instrument designed to
measure the refractive index of liquids and solids, as well as the Brix value
of sugar solutions. Combining visual targeting with digital readings, it
provides convenient measurement and clear result presentation for routine
laboratory testing and quality control.
With
a refractive index measurement range of 1.3000–1.7000 and a Brix range of
0–95%, the WYA-2S supports a wide variety of analytical applications involving
sugar solutions, food ingredients, chemical liquids, and other suitable
materials. Its temperature display and temperature-correction capability for
Brix measurements help users account for temperature-related variations in
measurement results.
The
instrument also features a standard printer interface for direct data printing,
making it suitable for laboratories that require convenient result recording
and traceability.

detailed sample comparison and laboratory analysis.
5. Brix Temperature
Correction: Supports temperature correction for Brix measurements to
improve result consistency under varying measurement conditions.
6. Temperature Display: Displays
temperature from 0°C to 50°C with a minimum indication of 0.1°C.
7. Standard Printer
Interface: Allows measurement data to be printed directly using a compatible printer,
supporting laboratory documentation.
8. Compact Laboratory
Design: With a weight of approximately 8 kg and dimensions of 330 × 180 × 380 mm, the
instrument can be accommodated on a laboratory workbench.
Working Principle
The
WYA-2S Digital Abbe Refractometer measures the refractive index of a sample by
analyzing how light changes direction when passing between materials with
different optical properties.
When
a suitable sample is placed on the measuring surface, the instrument uses the
optical boundary between the sample and the prism to determine its refractive
index. The result is expressed as (n_D), referring to refractive index measured
at the sodium D-line reference wavelength under specified conditions.
For
sugar solutions, the instrument can also display the Brix value, which
represents the concentration of dissolved sucrose in a solution under defined
measurement conditions. Temperature correction helps account for the effect of
temperature on Brix readings.
The
refractive index and Brix results can then be used for sample identification,
concentration assessment, process monitoring, and quality control, provided the
measurement method is appropriate for the sample being tested.
