A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...

Calibration solutions degrade over time, losing their ability to provide an accurate reference point for the meter. Similarly, contamination of calibration solutions also significantly impacts meter ...

The final (equilibrium) of acidic and acidified foods must be 4.60 or less. Calibrate your pH meter before testing foods. Prepare and test 2 to 3 samples to ensure an accurate pH value. Using a pH ...
