Pocket ATC pH meter

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..

PH meter anode storage fluid. The pH meter is a precision instrument. Correct use and proper maintenance are essential to enjoying your pH meter for a long time. Here are some important facts: When you buy an electrode, it is usually hydrated. First, let it soak in the storage solution for 4 hours. After each use, the sliding cap with the electrode must also be filled with its storage solution. This will keep your electrode working properly for much longer. Before the first measurement, the pH meter must be calibrated with buffer solutions. If the pH meter can only be calibrated at one point, use the buffer solution closest to your normal measurements. Be careful not to contaminate the buffer solution when calibrating. Therefore, never insert the electrode directly into the bottle, but measure it by pouring a small amount into a separate cup. After calibration, throw away the used cups, do not pour the liquid back into the bottle! Preferably, never touch the electrode, certainly not with your fingers. If you want to clean it, use only a soft cloth without rubbing the electrode..
