B-14BMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.• More accurate in one-handed operation: inexperienced operators measure signicantly more accurately with the new micrometer. • Ratchet function works both from the thimble and the speeder.• Rotating the thimble/speeder when the workpiece is between the anvil and spindle causes the ratchet mechanism to operate and apply a constant measuring force to the workpiece. • Clearly audible ratchet operation for reassurance that measurement is being performed at constant, preset force. • The speeder is always available for quick rotation of spindle. • A simple mechanism, which requires neither parts maintenance nor special technique, is employed in the constant-force device.• Heat-insulated frame.• Measuring faces: CarbideRatchet Thimble Micrometer SERIES 102 — Outside MicrometersGreatly improved accuracy and repeatability Technical Data Flatness:0.6μm/.000024”Parallelism:2μm/.00008”Measuring force: 5-10NStandard accessories: Reference bar, 1 pc(except for measuring range 0-25mm (0-1") models)Spanner (301336), 1 pcInternal structureMeasurement results of one-handed operation A beginner performed a test by measuring a workpiece 20 times using a conventional micrometer and a Ratchet Thimble Micrometer.
