Description
Overview

The QH5 M supports all dmq impact devices so that you can cover all portable hardness testing applications by quickly connecting and disconnecting devices.

Multiple impact devices usually means frequent changes in the device being used. But with CalTag technology - exclusive from demeq - changing devices does not require unit calibration.
