Katranji 300010 Sugar-Brix Refractometer
Product Description
The Sugar/Brix 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 the solution, the higher the reading on the scale. The product comes with a Prism, Calibration screw, Cover Plate, Barrel, and Eyepiece with a focus ring.
product Operating Procedures
- With the COVER PLATE open, clean the PRISM with a soft cloth to avoid scratching the surfaces.
- Aim the refractometer toward a light source and rotate the EYEPIECE to obtain the clearest focus.
- Adjustment of the null (reference point):
- Open the COVER PLATE.
- Apply a few drops of pure distilled water onto the PRISM platform.
- Close the COVER PLATE.
- Turn the CALIBRATION SCREW until the dark and light boundary line coincides with the bottom line of the scale.
- Carefully dry the prism platform and the cover.
- Place a few drops of the test solution on the prism and close the COVER PLATE so the solution spreads evenly on the prism.
- Aim the front of the refractometer towards the light source and focus the eyepiece on the boundary line of the light and dark hemispheres.
- The boundary line indicates the concentration of sugar in the test sample.
- After use, clean prisms with a cloth and remove any residue.
- The temperature of the null reference liquid should be at the same temperature as the sample solution. For variations in temperature, the null point should be adjusted once every 30 minutes.
Product Precautions
- Never submerge the unit, and do not let the liquid to seep into the unit’s body.
- Clean the refractometer after each use with a soft cotton cloth. Do not scratch the surface of the prisms.
- Store in a dry, clean, and non-corrosive environment. Avoid strong shocks.

INTRODUCTION
Your portable refractometer is a precision optical instrument designed to
measure the concentration of sugar in aqueous solutions. This unit features
automatic temperature compensation (ATC) which makes manual temperature
corrections unnecessary between 10 and 30°C. Its lightweight, and ergonomic
design makes it convenient for both
field and laboratory applications. It is excellent for quality assurance,
process control, and scientific 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 the solution, the higher the reading on the scale.
