The Mitutoyo 500-173 Absolute Digimatic Caliper has a measuring range of 0-12"/ 300mm with .0005"/ 0.01mm resolution. Includes SPC data output and a thumb roller. Features also include a large, clear LCD readout, inch/metric conversion and a Zero/Absolute key that allows the display to be zero-set at any slider position along the scale for incremental comparison measurements. This switch will also allow return to the absolute (ABS) coordinate and display of the true position from the origin point, which is usually the jaws-closed position.
