Double R Optics products

The Laboratory Refractometer DR 194 is designed for the Measurement of refractive  index, average dispersion of liquids, solids and for determination of percentage sugar content in agues solutions. In view of high accuracy achieved with the use of even a few drops of liquid or substance under test the refract metric measurement present a convenient and economical method of testing. They find their applications wherever the components of mixture show various indexes of refraction. The refract metric measurements are applied to research and control works in chemical and food industry.
