Our varied line of electronic, mechanical digital and regular depth micrometers are available with base lengths from 2-1/2-6" (63.5-150mm) and can measure depths up to 9" (225mm).

Unless otherwise noted under the individual tools, they all have these features:

  • A base shape design that will automatically position the fingers so that the base is easily held in place for measuring stability
