How to operate a pH Meter?

1. Remove the protective cap
2. Rinse the electrode with distilled water and dry with filter paper
3. Turn the pH on, the switch is located on top of the pH pen
4. Immerse the pH meter electrode in the solution to be tested
5. Stir gently and allow the reading to stabilise
6. After use, switch off the pH meter and again using distilled water clean the electrode and replace the protective cap

How to calibrate a pen pH Meter

1. Immerse the electrode in pH 6.86 buffer powder (at 25 degrees c) and gently shake the electrode
2. Regulate the trimmer (located beside the back clip) with a screwdriver (included in box) until the buffer solution matches he digital reading
3. Immerse the electrode in buffer powder 4.01 and repeat previous steps to correctly calibrate the pH range

What is pH?

pH is the measurement of the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a larger concentration of hydrogen ions than water are acid and have a pH value of less than 7. Liquids with a lower concentration of hydrogen ions, on the other hand, are base and have a pH value higher than 7. The pH scale runs from 1 to 14.

What effect does pH have on brewing?

The correct pH will help carry flavour and ensure optimal enzymatic activity, you need the correct temperatures for enzyme activity but it's also equally important to have the correct pH. Testing your pH levels will help you make better quality beer. Our tip for understanding pH is to take regular readings at different stages through the brewing process so you can really understand what's happening.
