Product advantages :
If you want to display and analyse more than 2 characteristic, a M400 could be more appropriate
The M3 is the last generation tool for dimensional control from 1 or 2 Inductive probes.
The M3 is the last generation of tool for dimensional control with an air gage : air ring, air plug gage, air fork etc. The M3 is compatible with all the air gage brands available making possible to keep your current air gage and to use this modern and versatile display.
The M3 Incremental makes it possible to connect 2 incremental probes (Heidenhain type) directly to the display. Also allows the use of linear rulers. There is also a TTL version for Magnescale or Mitutoyo probes (via adapters).
