TM-505B/1005B Series 176-Toolmaker's Microscopes

The Mitutoyo TM Series is a toolmakers’ microscope well suited for measuring dimensions and angles of machined metals. It also can be used to check the shape of screws and gears by attaching an optional reticle. The compact body makes it ideal for use on shop floors with limited space.

  • Angle measurement is performed easily by turning the angle scale disc to align the cross-hair reticle with the workpiece image.
  • Illumination intensity can be adjusted.
  • Included standard accessories create an overall magnification of 30X. Magnifications can be changed from 20 - 200X by using optional objectives and/or eyepieces.
