MATCOR Probe Anodes

Impressed Current Anodes

matcor_probe_anodeMATCOR probe anodes are used in impressed current cathodic protection systems for water boxes, internal surfaces of pipelines, vessels and other industrial applications.

MATCOR probe anode provides superior performance with the most advanced sealing system available. The MATCOR probe anode sealing is comprised of machined water stops, O-rings and sealing compounds subject to high pressure sealing during the final phase of assembly. MATCOR probe anodes are manufactured with a machined stainless steel housing and each probe anode is tested for water sealing and electrical isolation resistance. An optional conduit box is available
