The numerous methods for the measurement of thickness in laboratory or shop are treated in seven groups according to physical operating principles. Mechanical--weight/dimension relationships, acoustics, vibration, displacement with various conversions; chemical---stripping, spectrochemical analysis; electrical---dielectric breakdown, resistance, electrochemical, capacitance, thermoelectricity; magnetic ---attractive force, reluctance, saturation, inductance, eddy currents; optical---microscopy (also electron microscopy), interferometry, diffraction, shadow; X-ray---absorption, diffraction, backscatter, spectrometry; radioactive radiation---absorption, backscatter, tracers. Ranges, accuracies, advantages, and limitations are discussed. A bibliography of references, a limited list of suppliers, and a detailed index of the gages, methods, applications, and trade names covered are appended.
