Indicating element refractometer to measure the sugar content of must, especially grape must, according to the index of refraction forms the indicator plate (3) with zero plane (1), which is illustrated by the Czechoslovak normalized scale CNM ø or ø NM. From zero plane is also shown ø KMW scale, scale ø Bx and scale ø Oe. Refkraktometer is also useful for making distillates scale representation% VOL, which determines the percentage of alcohol corresponding to the sugar content. |
