Crevice corrosion is detected and its extent is qualitatively measured by use of a two-electrode, polarization-type probe. The two electrodes are fabricated of the same metal and have substantially equal surface areas. At least one of the electrodes is shaped to define a crevice area of relatively narrow width. The crevice area may be formed by cutting or milling a slot in the electrodes, by grooving or threading the electrodes or by encircling the electrodes with a sleevelike element of a nonconducting material.
