General Use
1
Open the daylight plate and apply one or two drops of the sample solution to
the surface of the prism. Hold the prism at an angle close to parallel with the
floor so the sample will not run off of the prism.
2
Gently close the daylight plate over the prism. The sample solution should
spread as a thin, even layer in between the daylight plate and the prism. By
looking through the daylight plate, ensure that the sample solution covers the
ENTIRE surface of the prism. If there are bubbles and gaps or if the sample
is only on one portion of the prism, the sample solution must be reapplied
(Figure 1). Inaccurate readings will result if the prism is not covered correctly.

Looking through the eyepiece, hold the refractometer and direct the daylight
plate upwards towards light. If the scale is not in focus, adjust it by gently
turning the eyepiece (rubber hood) either clockwise or counterclockwise. Be
careful not to overturn the focusing mechanism.

When the refractometer scale is viewed through the eyepiece, the upper field
of view will be seen as blue and the lower field will be seen as white (Figure 4).
The reading is taken at the point where the boundary line of the blue and white
fields crosses the scale (Figure 5). The value is the Brix/Specific Gravity
Beer Wort reading of the sample.

When each measurement is complete, the sample must be cleaned from
the prism using tissue paper and water.

- Page 2 Introduction Automatic Temperature Compensation Thank you for purchasing this VEE GEE Refractometer. With the user in mind, VEE GEE Refractometers are built from modern VEE GEE Model SGX-1 Refractometer is equipped with an Automatic Temperature Compensation (ATC) mechanism. designs and, with proper care, this instrument should provide many years of reliable performance. It’s recommended this Refractometers that do not feature such a mechanism must be recalibrated (zeroed) when shifts in ambient temperature manual is read entirely before using the refratometer for the first time.
