Introduction
The U.S. Solid Abbe Refractometer measures refractive index from 1.3000 to 1.7000 nD with an accuracy of ±0.0002 nD. It provides a direct 0–95% Brix scale for sucrose concentration measurement and is suitable for transparent and semitransparent liquids, flat polished solids, and mean-dispersion measurement.
The refractometer features a dispersion handwheel to clarify the light-and-dark boundary, a scale ring for mean-dispersion calculation, and four bath connectors for external temperature control from 0°C to 70°C after stabilization.
Applications
Features
- Refractive Index Measurement: Covers a 1.3000–1.7000 nD range with ±0.0002 nD accuracy for transparent and semitransparent liquid samples.
-
Direct Brix Reading: Measures sucrose concentration from 0–95% Brix with ±0.2% Brix accuracy, allowing sugar solutions to be checked directly on the upper scale.
- Liquid and Solid Testing: Tests transparent and semitransparent liquids as well as flat polished solids.
- Mean Dispersion Measurement: The dispersion handwheel clarifies the light-and-dark boundary, while the scale ring supports mean-dispersion calculation with an indication error of ±0.0005 nD.
- External Temperature Control: Four bath connectors support circulation from a constant-temperature bath for refractive-index measurements from 0°C to 70°C after stabilization.
