pH Calibration Procedure:
1: Use the red package to calibrate to a pH of 4.0 or the Green Package to 6.86 (at 25C or 77F). Our pH meters have automatic temperature adjustments.
2: Add the contents of one pack into one-cup (8 fl oz. / 250 ml) of water. It’s worthwhile to use 1/2 of the package with 4 fl oz of distilled water and refrigerate for several months; Depends upon how accurate the results wish to be.
3: For maximum accuracy, you would calibrate the usage of both the 4 and the 7 packages (see below).
4: Choose a tall container with a tight fitting lid to store the solution in the fridge to re-use.
5: Even though each pack is intended for single use, we found it remains quite accurate with a couple of uses.
6:To avoid spills when inserting the meter, we recommend a 12 oz or larger container. Generally to calibrate a pH meter you only wish to use one-fluid ounce of solution in a tall slender glass.
7: Run the pH meter under running water to make certain the bulb or felt pad is clean before the usage of the solution.
8: Use a small eye-glass screw driver to adjust the meter (comes with our pH meter). Rinse well before and after each use.
