To nd the refractive index or Brix value of any transparent or translucent liquid, the steps are similar to the
calibration procedure.
1. Place 2-3 drops of the sample liquid on the surface of the primary prism.
2. Close and lock the secondary prism. Be sure the liquid covers the prism surface completely, without any gaps
or bubbles.
3. Adjust the scale illuminator to provide the best illumination for the display.
4. Open the light cover.
5. Close the prism reector.
6. Focus the eyepiece on the crosshairs.
7. Turn the adjustment knob to nd the position of the halftone boundary line.
8. Turn the dispersion adjustment knob to remove color from (and sharpen the image of) the boundary line.
9. Turn the scale adjustment knob until the boundary line intersects with the crosshairs.
10. The refractive index and Brix values can be read from the scale beneath the crosshairs.
Measuring Liquids
1. The sample must have a smooth, polished surface. Place one drop of contact liquid (1-bromonaphthalene or
similar with higher RI than solid sample) on the smooth surface and place it on the primary prism (smooth side down).
2. Adjust the scale illuminator to provide the best illumination for the display.
3. CLOSE the prism reector.
4. Focus the eyepiece.
5. Turn the dispersion adjustment knob to remove color from (and sharpen the image of) the boundary line.
6. Turn the scale adjustment knob until the boundary line intersects with the crosshair.
7. The refractive index and Brix values can be read from the scale beneath the crosshair.
