The lifetime of a pH sensor has a substantial impact on the annual cost of pH measurements. Optimising four factors not only reduces costs, but can also optimise process control and efficiency.
These four factors are:
Calibration
Although calibration per se does not affect pH sensor lifetime, incorrect calibration can lead to sensor replacement without actually being necessary.
Maintenance
The measurement results obtained from a contaminated sensor can range from completely wrong to slow response. Correct maintenance is therefore a prerequisite.
Engineering expertise
A pH sensor is a high-tech precision instrument. Such sensors also require engineering expertise to get the best out of the measurement.
Sensor selection
The most important factor for best performance is the sensor choice itself. If the wrong pH sensor is chosen for the respective application, the lifetime drops significantly.
