DIGITAL ABBE REFRACTOMETERS Uses and Applications of the Abbe Refractometers ATAGO's Abbe Refractometers are widely used in a variety of fields; from basic research to product management. Uses and Applications For measuring the refractive index (nD) of liquid samples between 5 to 50˚C: DR-A1, DR-A1-Plus, and NAR-1T LIQUID. We recommendABBE MARK II Refractometer and describes proper set up, use and routine maintenance of the instrument. Sections 7.0 - 7.4 are applicable only to the LEICA ABBE MARK II Plus Refractometer. The LEICA ABBE MARK II Refractometer is a durable bench-top instrument. It provides efficient, reliable and repeatable readings in three modes: • % Solids .The refractometer is maintenance-free. The refractometer should be cleaned immediately before and after each use. This promotes long refractometer life and an accurate measurement result. 8 Storage Store the refractometer in a dry, non-corrosive environment, preferably between 10 °C and 30 °C. 9 Service

This kind of refractometer was designed by Ernst Abbe in 1869 as part of his work with Carl Zeiss, a German optical instrument maker. Abbe is also famed for the development of the numerical aperture formula for microscopes and for the prism which bears his name. Two such Abbe prisms are the key components of this refractometer.The explosive growth of laboratory work after WW 1 led a number of other companies to begin its manufacture as well, including Adam Hilgar and Stanley in Great Britain, and Spencer Lens Co., Bausch & Lomb, Gaertner, and Valentine in the U. S. Ernst Abbe constructed the first “Abbe” 3 refractometer in 1869. Five years later, in 1874, he .3、 Principle of Operation 4、 Construction 5、 How to Use the Instrument 6、 Maintenance 7、 Complete Set of the Instrument 8、 Addenda . 1 Purpose The Abbe Refractometer is intended for measuring the refractive index nD and the average dispersion nF – nC of transparent or translucent liquid, or solid substance (of which mainly .
