pH is one of the most common water quality parameters measured in a wide range of different applications.
Online pH measurement is traditionally carried out using a glass bulb electrode with a junction (or two) between the electrolyte and the sample. A better approach to minimise drift and reduce maintenance is to use a non-porous pH electrode so the electrolyte doesn’t become contaminated over time.
This makes also makes it the ideal pH sensor for samples with low conductivity or those with high or low pH.

Robust digital pH sensor for operation on TriBox controllers. Digital communication ensures safe and trouble-free signal transmission from the sensor to the controller.
Discover how a non-porous sensor is different to a traditional sensor and what differences it makes to operational costs and performance.
