Description
Application: Engelhard Capac Monitor, Model 50030 — analog push-to-read reference-cell meter for Capac impressed-current cathodic protection (ICCP) systems used on yacht and commercial hulls (bronze, steel, and aluminum). Serves as the helm/engine-room readout of hull-to-reference-cell potential, with factory-printed protected-value ranges on the dial (Bronze 0.55–0.75 V, Steel 0.80–0.95 V, Aluminum 0.90–1.05 V).
Condition: Used take-off. Aluminum housing and bezel show shop soil, oxidation, and light corrosion; lens is dusty but dial and pointer are clean and readable; rear meter movement shows minor verdigris. Sold untested and as-is — ideal for restoration of an existing Capac ICCP panel or as a display/reference piece.
Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
