The PHE-6820B electrode and assembly features a retractable design for insertion into tanks and main lines. The assembly, when used with a 1" full port or larger ball valve (user supplied), allows the electrode to be removed without shutting the system down. This electrode can be mounted in any location, even up through the bottom of a tank with the electrode surface facing upward. Its unique design affords mounting in any direction and is suitable for most systems’ inherent design. The flat surface design minimizes fouling and coating and eliminates electrode breakage. Turbulent flow across the electrode surface results in a scrubbing action that keeps the electrode clean. The flat surface electrode is specifically designed for difficult applications such as oily waste water, emulsions, lime slurries, and flocculants.

Rated 3 out of 5 by from No replacement Parts Available. Probe works well. Assembly is well built. Issue is they do not sell the cable individually. If the cable goes bad which is a common pH probe issue you will have to re-purchase the entire unit.
