Drinking water

Control your water quality

pH measurement is essential in drinking water production plants; there are usually several measuring points throughout the whole production process

Where is the pH measured?


Raw water

Analysis of incoming water to understand if the pH level is suitable for cleaning chemicals (flocculants) to function.



Measurements during filtration, segmentation, fluctuation processes to exclude the possibility of plant damages.


Finished drinking water

Knowing the final product’s pH value is essential to ensure healthy alkaline levels for human consumption, and hence a high quality product

Why does it matter?

pH remains one of the core values to be measured during the whole process of producing drinking water. PH is a key parameter to control changes in raw water, e.g. inflow from external water sources with different quality, appropriate conditions to prevent damages to other instruments, optimize the chlorine and in general to ensure the highest quality output. A perfect pH sensor for drinking water industry should provide:

  • high accuracy and repeatability

  • long term, reliable measurement

  • low maintenance (cleaning) and easy calibration

  • easy handling
