refractometer digital 0-230 Oe + 0-50 Brix

Determine the density and sugar content of your liquids in 2 seconds! This digital refractometer is suitable for wort and juices. Supplied with a 9-volt battery. Scale: 0 to 50 % Brix / 0 to 230 ° Oechsle ie measures dissolved sugars up to 609.53g/l, / 0 to 42 ° kmw / 0 to 80 ° C (32 to 176 ° F). Reading: 0.1 % Brix / 1 ° Oechsle / 0.1 ° kmw / 0.1 ° C (0.1 ° F). Accuracy: ± 0.2 % Brix / ± 1 ° Oechsle / ± 0.2 ° kmw / 0.3 ° C (± 0.5 ° F). Calibration: automatic with demi-water. Temperature compensation (ATC): automatic at 10-40 ° C. Measurement time: 1.5 seconds. power source: 9V battery, enough for about 5000 measurements. Weight: 420 grams Oechsle scale (Oechsle Mostwaage, Oechsle degree) The Oechsle Mostwaage is designed to measure the sweetness of wine must (grape juice, grape must) and is used in Germany, Switzerland and Luxembourg. It was developed by the German mechanic, jeweler and inventor Ferdinand Oechsle in the early 19th century (circa 1820). The sweetness value of the wine wort is derived from the density of the wine wort at 20°C. It is based on the assumption that the density (specific gravity) of the wine wort is greater than the density of water. This means that the density of the wine must is greater than 1.0000 kg / dm3. The Oechsle value represents the reduced value of the density of wine wort (reduced - 1) * 1000 - for example, if the density of wine wort is 1.0820 kg / dm3, the value according to the Oechsle scale is 82 ° Oe.
