DESCRIPTION

OPERATING PROCEDURE

1. With the COVER PLATE open, clean the PRISM with a

soft cloth to avoid scratching the surface.

2. Aim the refractometer toward a light source and rotate

the EYEPIECE to obtain the clearest focus.

3. Zero Point Calibration:

A. Open the COVER PLATE.

B. Apply a few drops of the included Distilled Water

onto the PRISM platform.

C. Close the COVER PLATE.

D. Turn the CALIBRATION SCREW until the dark and

light boundary line coincides with the bottom line

of the scale.

4. Carefully dry the prism platform and COVER PLATE.

5. Place a few drops of the test solution on the prism and

close the COVER PLATE so the solution spreads evenly

on the prism.

6. Aim the front of the refractometer towards the light

source and focus the eyepiece on the boundary line.

7. The boundary line indicates the v/v percentage of

alcohol in the test sample at 20°C.

8. After use, clean the prism with distilled water and a cloth

to remove any residue.

Note: The temperature of the zero point calibration

should be at the same temperature as the test solution.

For variations in temperature the zero point should be

adjusted once every 30 minutes.

Note: For beer or wine, this unit is to be used in conjunction

with a hydrometer before and after fermentation process.

PRECAUTIONS

Never submerge the unit, and do not let liquid seep into the

unit’s body. Clean the refractometer after each use with a soft

cotton cloth. Do not scratch surface of the prism. Store in a dry,

clean, and non-corrosive environment. Avoid strong impacts.
