Automation of pH and ORP measuring points
Automatic cleaning, validation, calibration and adjustment of pH and ORP sensors
The automation of a pH measuring point makes sensor maintenance considerably easier: work is limited to planned exchanges of sensors, buffers and cleaning solution. All the rest is done automatically by the system, offering consistent high quality, which is difficult to achieve manually. This gives plant personnel more time for other process-related tasks and has the great advantage that personnel have to visit difficult-to-access and potentially dangerous measuring points less frequently.

Automated measuring points provide reliable, accurate and reproducible measured values.
When is the automation of a measuring point useful?
The sensors must be cleaned and/or calibrated frequently.
The measuring point is difficult to access.
The measuring point is in a harmful environment.
The process requires reproducible precise pH measurement.
The process requires measurement at frequent intervals.
The performance of the measuring point must be controlled and documented frequently.
Fordele
Less frequent and shorter plant personnel visits in difficult-to-access, harsh or harmful areas.
Manual maintenance work is limited to planned exchanges of sensors, buffers and cleaning solution.
Automated cleaning increases the sensor availability and lifetime, particularly in aggressive or contaminated media.
Automated calibration improves the reliability, accuracy and reproducibility of the measured values.
