The measurement result is most accurate at 20 °C, so the temperature should always be determined and the distortions determined using a

correction table. However, there are also refractometers that have an automatic temperature correction which of course greatly increases the

measuring comfort.

What is the Abbe refractometer used for?

Many applications aim to determine the concentration in a carrier medium. A traditional example is the determination of the sugar content in

mostly aqueous solutions. For example, by determining the sugar concentration of a grape, its degree of ripeness can be determined, which

makes it interesting for winemakers. The refractometer can also measure the original wort when brewing beer and the water content in honey.

But a refractometer can also be a real aid in industry, for example the oil-water concentration in cooling emulsion mixtures in metalworking

machines or the acid concentration in batteries can be determined. A refractometer can also be found in medicine, for example the protein

content in urine can be measured. There are many other areas of application in which a refractometer is useful and greatly simplifies work. In

order to ensure comparability of the results, separate scales have now been established (degrees Oechsle, degrees Brix, degrees Plato).

Refractometers are mostly equipped with the double scale % mas sucrose (Brix)/°Oe or triple scale % mas sucrose (Brix)/°Oe/KMW-Babo. The

% mas sucrose (Brix) scale is valid internationally. The Oechsle scale 0-140°Oe is valid for fruit juices, foreign grape musts and distilling mashes.

For German grape musts only the Oechsle scale 30-140°Oe is valid. Refractometers with this scale are marked with a "D".
