Calibration
Often, there is a misinterpretation of the meanings of “calibration” and “maintenance.”
Maintenance activities focus on CHANGEABLE effects, for example:
- Cleaning a dirty sensor
Calibration, on the other hand, will compensate for UNCHANGEABLE effects. These are:
- Aging of the pH glass, usually caused by chemicals in the process or high temperatures
- Poisoning or depletion of the reference chamber
Calibration itself will not extend the life of a sensor, but a sensor that is not calibrated correctly can cause unreliable measurements. In some cases, that even results in unnecessary replacements. Do not underestimate the importance of calibration – review the do’s and don’ts of pH calibration.
