Calibrating solution 71% Brix, 5 ml

refractometer is a precision optical instrument that determines the density of a liquid based on its refractive index. The refractometer has two scales that can be read simultaneously. Brix and Viscosity SG reading. Accurate but easy to use: just put a few drops of liquid on the prism and the density is read directly. Scale 0-32% Brix, reading per 0.2% ; SG scale 1.000-1.130SG, reading with 0.001 accuracy ; automatic temperature correction (+10...+30C), High-quality aluminum construction, Easy to calibrate, Strong packaging, Contents: refractometer, pipette, mini-screwdriver, storage bag, soft cleaning cloth. Glass hydrometers follow Archimedes' law: any body in a liquid or gas is subject to a buoyant force equal to the weight of the liquid or gas displaced by that body. A gram is the mass of 1cm³/1ml of pure water. Specific gravity is mass per unit volume - g / cm³. The specific gravity of pure water is 1 g/cm³ or 1 (1.000). Scale for measuring Brix sugar content from 0 to 32% (0 to 32 ° Bx), accuracy is 0.2% (° Bx). Degree of Brix (° Bx). The scale in Brix degrees (symbol ° Bx) is designed to determine how many grams of sucrose are dissolved in 100g of sugar aqueous solution. The degree of Brix indicates the strength of the solution as a percentage by mass (mass fraction of sugar). If you measure a value of 25°Bx, it means that 25g of sucrose is dissolved in 100g of aqueous solution. In other words, 100g of sucrose in an aqueous solution contains 25g of sucrose and 75g of water. Therefore, the percentage sign (%) is sometimes used as a unit, since the sucrose content is the percentage of sucrose by weight. Brix results are fully convertible to refractive index (degrees of Brix are defined according to the international standard ICUMSA), so refractometers equipped with a Brix scale can be used to measure any chemical..

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.

refractometer is a precision optical instrument that determines the density of a liquid based on its refractive index. The refractometer has three scales that can be read simultaneously. This model is specially designed for beekeepers, but it can also be used for the production of syrups, preserves, etc. Accurate but easy to use: just put a few drops of liquid on the prism and the density is read directly.

Calibration and filling fluid for PH-110 model What is pH? pH is a measurement of the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a higher concentration of hydrogen ions than water are acids and the pH value is less than 7. Liquids with a lower concentration of hydrogen ions are more alkaline and the pH value is greater than 7. The calculated pH value is 1-14..

VINOFERM acid meter A set for easy and quick measurement of the acidity of red and white wines: partially fill the cylinder with the liquid to be measured, drop the blue indicator until the color turns blue, you will immediately get the acidity level! Contains 1 special measuring cylinder, 1 bottle of Vinoferm® blue indicator and litmus paper. Very easy to use. It is also suitable for determining free sulphide using an iodine solution (ordered separately). What is pH? pH is a measurement of the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a higher concentration of hydrogen ions than water are acids and the pH value is less than 7. Liquids with a lower concentration of hydrogen ions are more alkaline and the pH value is greater than 7. The calculated pH value is 1-14. Use: To determine the amount of acid in wine wort or wine. PRINCIPLE: Amount of acidity = amount of added blue indicator (alkaline liquid) needed to reach neutralization point (color change occurs). Acidity is expressed in tartaric acid. HOW TO USE: Fill the special measuring cylinder with (filtered) wine or juice up to the 0 mark. Add a few ml of blue indicator and shake (close the measuring cylinder with your thumb and turn it over) Repeat the procedure until the color has turned dark green (not quite) blue. This is the point of neutralization. The number of ml in the measuring cylinder (wine with blue indicator) gives us the total acidity level in grams per liter (7-8 gr/l is ideal for wine). We check the result with litmus paper: we add 1 drop to the paper and if it does not cause a color change, then the result is correct. If it turns red, the liquid is still too acidic and blue liquid must be added. If it turns blue/violet, it is too alkaline and the test must be repeated. For dark red wine, the color change is more difficult to see and must be diluted to ½ or 1/3 with distilled water and the result multiplied by 2 or 3. For highly acidic juices, also dilute as the measuring cylinder is limited to 20. Cider and table wines (6-10 ° alc.) should have an acidity of 6-8 g/l (so on average 7 g/). Wines and sweet wines (13-15 ° alk.) can have an acidity of 8-10 ° gr / l (average 9 gr / l). Too little acid: e.g. only 4 gr/l. For table wine, add (7-4 =) 3 g of tartaric acid or 3.6 g of lactic acid per 80% liter. For wines or sweet wines, add (9-4 gr/l) 5 g of tartaric acid or 6 g of lactic acid per 80% liter. Determination of free sulphite with iodine-liquid (which does not contain ascorbic acid or vitamin C). The color change is blue (10sec.). The number of readings in milliliters per cylinder, multiplied by 10, gives you the amount of free sulfide (SO2) expressed in milligrams per liter. Maximum allowed: wine 50 ml / l. the average is 35 mg/l..
