ZEDsatellite

Precise measuring directly at the test object

The ZEDsatellite decentralized measuring and testing modules enable measuring directly at the test object, increasing measuring accuracy and reliability.

The data from the available measuring methods can be easily read out centrally via ZEDbox or any other unit from the ZED device family.
