INTRODUCTION

Your portable refractometer is a precision optical instrument

designed to measure the concentration of sugar in aqueous

solutions. It utilized the standardized Brix scale which is

accurate and easy to read. The unit’s lightweight, ergonomic

design makes it convenient for both laboratory and eld

applications. It is excellent for quality assurance, process

control requirements, and scientic research.

The refractometer operates on the principle that as the

concentration or density of a solution increases, its refractive

index changes proportionately. The refractive angle

measured by your refractometer registers on the scale. The

larger the concentration of sugar in solution, the higher the

reading on the scale.

PANEL DESCRIPTION:

Cover Plate (1)

Light reecting window (2)

Refracting prism (3)

Calibration screw (4)

Telescopic barrel (5)

Scale selector (6)

Eyepiece with focus ring (7)

OPERATING PROCEDURES

1. With the COVER PLATE (1) open, carefully clean the

PRISM (3) and REFLECTING WINDOW (2) with a soft

cloth. Avoid scratching the surfaces.

2. Aim the refractometer toward a light source and select

the 0-50% scale by rotating the SCALE SELECTOR (6).

3. Rotate the EYEPIECE (7) to obtain the clearest focus.

4. Adjustment of the null (reference point):

A. Open the COVER PLATE (1).

B. Apply a few drops of pure distilled water onto the

REFRACTING PRISM (3).

C. Close the COVER PLATE (1).

D. Turn the CALIBRATION SCREW (4) so that the dark

and light boundary line coincides exactly with the 0%

line reading on the scale in the 0-50% range.

5. Carefully dry the prism platform and the LIGHT

REFLECTING WINDOW (2) with a soft cloth.

6. To test your sugar sample, rotate the SCALE SELECTOR

(6) to select the 0-50% range or the 50-80% range.

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

close the COVER PLATE (1) so the solution spreads

evenly on the prism.

8. Aim the light reecting windows toward the light source

and focus the eyepiece on the boundary line of the light

and dark hemispheres.

9. The boundary line indicates the concentration of sugar in

the test sample.

10. If the boundary line is too low or too high to be read on

the scale you selected, rotate the SCALE SELECTOR

(6) to the other scale.

11. After use, clean the refracting and illuminating prisms

with a soft cloth to remove any surface residue.

12. The temperature of the null reference liquid should be

at the same temperature as the sample solution. For

variations in temperature during use, the null point

should be recalibrated once every 30 minutes.

TEMPERATURE CORRECTION

Your refractometer is designed to operate with distilled

water and sample solutions at a standard temperature of

20°C (68°F). To compensate for temperature conditions

other than 20°C, use the Temperature Correction Table on

Page 6.

Add to the reading when the temperature is above

20°C. Example: Actual temperature is 30°C. The

boundary line reads a concentration of 15%. Refer to

the Temperature Correction Table and locate the 15%

concentration column. Follow this column down to the row

that corresponds to the temperature of 30°C. At the 0.78

correction point, the actual concentration percent is

15% + 0.78%, or 15.78%.

Subtract from the reading when the temperature is

below 20°C Example: Actual temperature is 16°C. The

boundary line reads a concentration of 40%. Refer to

the Temperature Correction Table and locate the 40%

concentration column. Follow this column down to the row

that corresponds to the temperature of 16°C. At the 0.30

correction point, the actual concentration percent is

40% - 0.30%, or 39.70%.

If the null liquid (distilled water) is the same temperature as

the test sample and the null line of distilled water reads 0%,

it is not necessary to refer to the correction table.

PRECAUTIONS

With reasonable care, your refractometer’s reliability,

precision and optical performance will not change.

● Never submerge the unit, and do not let liquid to

seep into the unit’s body.

● Clean the refractometer after each use with a soft

cotton cloth. Do not scratch surface of the prisms.

● Store in a dry, clean, and non-corrosive environment.

● Avoid strong shocks.
