DM-13 Differential Micrometers offer sub-micron resolution in a unique design that achieves long range and fine adjustability in a single micrometer. Model DM-13 has a 13 mm overall range with 0.2 mm fine adjustment range. It employs the same mounting bezel as our standard SM Series Micrometers, so it may be used to easily upgrade an existing instrument to provide, in most cases, a factor of 10 improvement in resolution. DM-13 provides excellent linearity and absolute accuracy better than 1%, and its unique design exhibits no harmonic motion errors typical of conventional differential screws.
