Tube Micrometer-Cylindrical Anvil

The Mitutoyo spherical face micrometer measures the thickness of tube walls within +/- 0.00015” of accuracy.

Features & Benefits

The Mitutoyo tube micrometer is available with either flat or spherical measuring face options to measure the wall thickness of various tubes. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements and eliminates over-speed error.

  • Available with pin, spherical and cylindrical anvils
  • Available in Metric and Inch models
  • Designed to measure the wall thickness of various tubing
  • Measuring surfaces are constructed of carbide to reduce wear
  • Ratchet mechanism provides an audible click to ensure measurement is being performed at a constant force
  • Knurled friction thimbles provide quick adjustments even when wearing gloves
  • Satin chrome finish on the sleeve and laser etched measurements on thimble for easier reading
  • Frame has a baked enamel finish for durability and longer lifespan
  • Includes a standard bar except for 0-25 mm and 0-1” model
  • Supplied in fitted plastic case
