MATCOR probe anodes are impressed current MMO or platinum/titanium anodes for cathodic protection of water boxes, internal pipeline surfaces, and industrial vessels. Each features a machined stainless steel housing and is 100% factory-tested for water sealing and electrical isolation resistance.
Additional options:
The inactive area of the probe anode can be provided in varying lengths to accommodate the design and installation. If separation from the structure is not a concern, a minimum inactive length of 3-inches (76.2 mm) is acceptable.
