Mitutoyo America Corporation Micrometer MI-129132

Outside micrometers are used for measuring the thickness or outside diameter of small parts or fittings with high accuracy. Similar in appearance to a C-clamp, the object to be measured is clamped between the anvil (the stationary end of the clamp) and the spindle (the moving part of the clamp). The clamp opens and closes by turning an internal screw. On analog micrometers, measurement is calculated by reading the lines and numbering system that appears on the thimble and sleeve. . Interchangeable rods provide a wide measuring range. With ratchet stop for constant force. The rod length can be adjusted in 1in or 25mm increments.
