1. A corrosion monitoring system, comprising:
- a. means for sensing galvanic corrosion, with said means disposed in an environment where galvanic corrosion of preselected metals is to be monitored, whereby when galvanic corrosion is sensed an amount of galvanic current flows from said means, wherein said means includes a sensor head device which further includes a galvanic couple made of metals identical to said preselected metals to be monitored for galvanic conversion, with said couple coiled in the shape of a spiral and potted in a housing made of electrically insulating material; and
b. means, in electrical connection with said galvanic corrosion sensing means, for amplifying, integrating, and storing in a non-volatile memory for recalling and displaying said amount of galvanic current that is flowing and has flowed from said galvanic corrosion sensing means, wherein said amplifying, integrating, and storing means includes;
(1) amplifier means in electrical connection with said galvanic corrosion sensing means;
(1) integrator means in electrical connection with said amplifier means;
(3) non-volatile memory means in electrical connection with said integrator means, wherein this means includes a bubble memory component; and
(4) digital display means in electrical connection with said non-volatile memory means.

Abstract
A system for detecting and measuring corrosive reaction of metals in an environment. The system includes: a remotely placeable sensor head containing a galvanic couple made of metals identical to those involved in the corrosion problem, with the couple coiled in the shape of a sprial; and, operatively associated electronic circuitry to amplify, integrate, and store in a non-volatile memory, e.g., a bubble type memory, for future recall the amount of galvanic current that is flowing and that has flowed when corrosion is, or has been, occurring.
