CISN00001 Digital PH Sensor

In a world of endless consumer choice, it becomes increasingly more difficult to find exactly the right tool for the job. Even measuring the pH of water brings up a head scratching question of “where do I start?” A quick Google search returns many solutions from pH test strips to advanced sensor systems, maybe erring more on the light-hearted consumer side. Based on our field experience, we will break down the types of pH sensors you need to know, and how the different variations will satisfy any pH application you seek.

One of the most important considerations when selecting a pH probe is the contaminants the probe may be exposed to. Harsh chemicals and suspended solids may cause pH probes to fail. In applications with these contaminants, it is important to select a durable sensor that is easily replaced. Light duty applications involving monitoring of cleaner water may prioritize other considerations, such as ease of use.


Accusensor offers a range of pH probes designed for online monitoring of clean water, dirty water, and everything in between. Some common applications are covered in the tabs below. Swimming pool monitoring is an example of a light duty application, while wastewater monitoring involves more heavy contamination. View and compare product recommendations for these and other similar applications. Every application is different – our experts are available to provide individual recommendations.
