How is it used?

This smart digital sensor is designed for use with our modular flow-cell allowing a number of sensors to be connected in series for a true plug and play measurement solution.

 

Where can it be used?

The membrane covered design makes it ideal for measuring either free or total chlorine without the need for any additional sample buffering - even in applications where the pH may fluctuate! Its ability to cope with minimal sample flow makes it ideal for applications such as drinking water.

 

What makes this a "Star" product?

Outstanding measurement stability – simplified! This smart sensor is so easy to use thanks to ABB’s EZLink™ technology and when combined with the Steady-flow module provides stable measurement independent of variations in sample flow even down to 1 l/hr!
