Features & Benefits

The Mitutoyo digital sheet metal micrometer is available with a 6-inch or 12-inch throat, allowing the user to take measurements in the middle of sheets of metal, plastic, rubber and paper with high accuracy. Readings are displayed on an easy-to-read LCD readout with accessible function buttons. The coolant-proof micrometer’s ratchet thimble mechanism provides a constant measuring force on the spindle to ensure accurate, repeatable measurements.
