A simple, low cost test instrument for measuring effectiveness of a corrosion inhibiting film. It employs solid state integrated circuits and applies an AC signal across the film. The amplitude of the signal is less than that which would damage the film, and the electrical resistance is a measure of the inhibitor effectiveness.
