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 ...

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 ...

What is pH sensor calibration? Calibration is the determination of the parameters of the calibration curve: slope and offset. The perfect electrode has a slope of 100% and an offset of 0 mV at pH 7.00 ...
