M1 and M3 displays are designed to make various dimensional controls from 1 or 2 measuring input, including:
- Half bridge or LVDT Inductive probes from Metro (Example M804S), Tesa (Example GT21), Mahr
(Example P2004M), etc...
- Air gages. Compatible with all brands.

- Each input of the display can be replaced by a channel from an external module or from a Solartron Orbit
probe. Example to combine air gage and contact probe.
The M1&M3 can be used on very simple manual applications up to the most complex ones in fully automated machines.
These display units are extremely easy to use and to program with a user-friendly interface and intuitive
