Some methods to measure the plate thickness were reviewed. Especially magnetic, radiation and ultrasonic thickness meters were illustrated. Magnetic methods were explained for the direct current type, the alternating current type and the continuously measuring type, which were developed in Japan. The radiant ray methods, such as the X-ray, beta ray and gamma ray penetration types and the gamma ray scattering type were quoted from American magazines. Some Japanese experiments of the penetration type were mentioned. The ultrasonic thickness meter of both the audible type and the cathode ray tube type were explained. Some Japanese examples using them were mentioned. Merits and demerits of magnetic methods, radiant ray methods and ultrasonic methods were discussed.
