ProMinent® has been manufacturing instrumentation equipment and sensors, specifically for the water treatment market for over 30 years. The pH sensors offer optimum life and precise control for most aquatics applications. ProMinent® offers a two year warranty and all SN6 connections are sealed to prevent exposure to the elements. Optimum performance is achieved when sensors are mounted in a modular proprietary clear PVC housing that can be retrofitted in the field. All components, including a controller, can be assembled on a back panel that can easily be mounted to any wall.
