Overview
Connect a dmq type G impact device to the QH5 and measure the hardness in massive, founded, and or forged parts with rough surface finishes. In Brinell measure up to 650 HB.

All QH5 models feature histogram graphics, real time statistics, selectable viewing modes, a Data Logger to store 32000 readings that can be sent to a PC, and much more.
