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