USE OF A REFRACTOR

Using the instrument is simple. First the surfaces of the prism and the cover are washed with distilled water and carefully wiped (This cleaning is done after each use of the instrument).

Calibration

Before the measurement is made, the instrument is adjusted by placing 1-2 drops of distilled water at a temperature of 20 ° C, on the surface of the prism covered with the movable cover. Looking at the field of view in the light, the line separating the light from the dark field must coincide with the 0 of the scale, if it does not coincide then turning the adjusting screw is arranged to coincide.

Measurement

After adjusting the instrument, 1-2 drops of the must are placed on the surface of the prism and the field of view in the light is observed. The reading occurs when by moving the instrument screw, the dividing line separating the light from the dark field is clearly displayed. The number of the scale corresponding to the dividing line gives the must content of sugar in% (Brix points, where 1 Brix = 1% sugar by weight)

For example, if the separation line is at 20 then the must contains 20% by weight sugar.

The indicators on the scale are set to 20 ° C. So if the must has a different temperature, then the result is corrected by adding if the temperature is higher or by subtracting if it is lower, of 0.2% per 3 degrees difference. The correction is made with the help of the Tables included in the product.
