Reichert Analytical Instruments Auto Abbe Refractometers will provide readings for refractive index, temperature compensated refractive index, % solids and temperature compensated % solids. The % solids and temperature compensated % solids scales in channel 1 are the International Commission for Uniform Methods of Sugar Analysis (ICUMSA) sucrose or "Brix" scales. Temperature is accurately measured by a thermistor at the prism surface where the sample is placed. Photosensing optices provide an extremely accurate and reproducible reading of the shadowline. The Reichert Analytical Instruments Auto Abbe display can be read to 0.0001 (0.00001 in the extended display mode) or 0.1% solids (0.01% in the extended display mode). Final measurement value is calculated from an average of 56 individual scans of the shadowline sensor all performed in a fraction of a second.
