Product Information
Refractometer
The Refractometer is a device that measures the refractive index of a
liquid sample. It can measure the concentration of a solution by determining
the amount of light that is refracted as it passes through the sample. This
particular model has a range of 0-80% Brix and comes with a calibration screw
and distilled water for calibration.
Product Usage Instructions
- Open the COVER PLATE and clean the PRISM with a soft cloth to avoid scratching the surface.
- Aim the refractometer toward a light source and rotate the EYEPIECE to obtain the clearest focus.
- Perform Zero Point Calibration:
- Open the COVER PLATE.
- Apply a few drops of the included 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 COVER PLATE.
- Place a few drops of the test solution on the prism.
- Close the COVER PLATE.
- Look through the EYEPIECE and read the Brix value on the scale.
- 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.
DESCRIPTION
OPERATING PROCEDURE
- With the COVER PLATE open, clean the PRISM with a soft cloth to avoid scratching the surface.
- Aim the refractometer toward a light source and rotate the EYEPIECE to obtain the clearest focus.
- 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.
- Carefully dry the prism platform and COVER PLATE.
- 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.
- The boundary line indicates the brix percentage of the test sample at 20°C.
- 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.
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 the surface of the prism.
- Store in a dry, clean, and non-corrosive environment.
- Avoid strong impacts.
