Operation
At the beginning of the measuring procedure, carefully clean the hinged lid and the prism and
then dry them. Now place 1-2 drops of the sample on the prism. When closing the hinged lid,
the sample is evenly distributed between the lid and the prism. To put the sample on the main
prism, you can use the pipette. Make sure that no air bubbles form as this would negatively
affect the measurement result. By moving the hinged lid slightly, the sample liquid can be
distributed evenly. Now hold the refractometer against bright daylight. You can now see the
scale through the eyepiece. The value is read between the light / dark border. By turning the
eyepiece, you can focus the scale if necessary. To prevent deposits from forming on the prism
and the lid, the device should be carefully cleaned and dried after each measuring process.
Refractometers work according to the principle of light refraction. With these devices, you can
easily and accurately determine the concentration of e. g. starch, glues, adhesives..., the mixing
ratio of liquid media and the sugar content of milk, juice, wine.... Thus, the devices can be used
in many industries as a quick measuring instrument in production and laboratories. All models
have automatic temperature compensation (ATC).
