2 Operation

At the beginning of the measuring process, the prism cover and prism must be carefully cleaned and then dried. Now place 1-2 drops of the sample on the prism. When the prism cover is closed, the sample is distributed evenly between the cover and prism. To place the sample on the prism, you can use the pipette. Please ensure that no air bubbles are formed - this would impair the measurement result. By moving the prism cover slightly, the sample liquid can be distributed evenly. Switch on the LED illumination on the prism cover and look through the eyepiece. By turning the eyepiece, you can adjust the sharpness of the displayed scale. The value can be read from the line between the light/dark boundary. To prevent deposits from forming on the prism and its cover, the instrument should be carefully cleaned and dried after each measurement. Clean the refractometer with a soft cloth. Never clean the instrument with running water as this could enter the LED illumination in the prism cover and lead to its destruction.

The refractometers work according to the principle of light refraction. With these instruments you can easily and accurately determine the concentration of e. g. starch, glues, adhesives, etc., the mixing ratio of liquid media and the sugar content of milk, juice, wine, etc. Therefore, the instruments can be used in many industries as a quick measuring instrument in production and laboratory. Several models, all with automatic temperature compensation (ATC), are available.

5 Calibration

The instrument must also be carefully cleaned and dried before calibration. Now apply 1-2 drops of distilled water to the prism. If the light/dark line is not at 0 % (waterline), this can be adjusted using the calibration screw on the top of the instrument, behind the prism cover. The screwdriver included in the delivery is used for this purpose.

6 Important notes:

• The prism cover and the prism should be kept clean; dirt impairs the measuring accuracy.
• Avoid scratches on the prism and the hinged cover; these also have a negative effect on the measurement.
• Do not use harsh, aggressive cleaning agents but only a damp cloth. Then dry the device well. Never clean the unit under water as this could enter the instrument.
• Avoid shocks and impacts as this can destroy the optics.
• Store the instrument in a dry place.

8 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.

If you have any questions, please contact PCE Instruments.
