Ony digital coordinate measuring systems consist of lineer scales, high density probes and digital readouts.

They can measure the coordinates in the density of  0.1 micron for probes and 5 micron for the lineer scales  by not being affected from dust, oil or vibration.  

These are the unreplecable, long life coordinate measuring systems of quality control ateliers and sub suppliers ateliers.  The biggest advantage is the high quality which ensures that the you can measure up with the same density after many many years even.  

Main features:

Lineer scales: from 150 mm to 30.000 mm in lenght and from 0.005 mm to 0.01 mm in density.   Probes: from 2 mm stroke to 150 mm stroke.  From 0.05 micron to 5 micron density.
