Analog Thickness Gauge is a precision instrument for measuring the Thickness of paper, Plastic films, Laminates, Foil, or Board. A dial-type micrometer is mounted on the base with a dead weight on top to develop a uniform, reproducible constant pressure. The total system is closed in an air-tight, transparent enclosure protecting dirt & dust. This is applied to test the thickness of flat sheet specimens. It measures up to the standard of paper and cardboard thickness testing methods - - ISO 534, ISO438, GB/T451.3, and GB/T1938.
