Overview
The ULM 520 S-E is an universal length measuring instrument with direct measuring range over entire device length. It uses comparator with horizontal machine base (highly homogeneous, rigid granite) for very high precision calibration.
 
Application:
Calibration of:-
– Plain plug gages and gage rings
– Setting gage rings
– Snap gages
– Spherical gage blocks, internal micrometers
– Gage blocks
– Thread gages
– Taper thread gages
– Gear gages
– Dial indicators
– Dial comparators
– 2-point bore gages
– Outside micrometers
– 2-point inside micrometers
