wine scale VINOFERM with thermometer

For accurate determination of alcohol and residual sugar, also during fermentation. Based on the principle of double density measurement: first measurement with alcohol, second measurement without alcohol (after steaming). Requires a 250 ml measuring cylinder. Length: 31 cm, accuracy 1/100% (fi 10.44%) The principle is very simple and consists of two measurements: 1. measure the liquid with alcohol 2. measure without alcohol There is a built-in thermometer for the most accurate work possible. The measurement is required at a temperature of 20 °C Example of use: Fill the measuring cylinder with exactly 250 ml of liquid for measurement. The first measurement must be done, for example, using the device at a temperature of 20°C. The first measurement is, for example, -7. At this point, the contents of the measuring cylinder (250 ml) must be poured into a container (e.g. Pyrex Erlenmeyer or stainless steel). The content must be boiled for at least 20 minutes or until half of it evaporates. At this stage, we are sure that there is no alcohol left in the liquid. Cool the drink and pour again into the same measuring cylinder. Fill the measuring cylinder to exactly 250ml with distilled water. Repeat the measurement again at 20°C. For example, the result is +8.5. Results: 1st measurement 1 -7.0 ° Oechsle 2nd measurement 2 + 8.5 ° Oechsle Difference 15.5 ° Oechsle. Refer to the table provided with the included device... you will find the exact alcohol reading. The number (difference) obtained in our example (15.5 ° Oe) corresponds to an alcohol content of 11.73%. Using the second measurement, you can calculate the extract. Using the second table below, we see that + 8.5 ° Oe corresponds to 21.9 g / l. Thanks to its accuracy, this meter is well suited for determining the alcohol and sugar levels of a drink after fermentation..
