EQUIPMENT DESCRIPTION AND MEASUREMENT PROCESS
Type D :
Standard impact device for most hardness testing tasks
Type DC :
Extremely short impact device for measurements at
inaccessible locations or in pipes
Type C :
Impact device with lower impact energy e.g. for
measurements on surface-hardened parts. The
impressions are approximately only half as deep as in case of
impact device D, however, the requirements on the surface
quality are higher.
Type D+15:
The impact device has a recessed reactance coil and a
smaller placement surface (11 mm x 14 mm instead of
20
mm) for hardness measuring in slots and deepened areas.
Type DL :
Impact device with longer impact body. The diameter of the
front pipe is 4.2 mm.
Type G :
The impact energy increased with type G for measurements
on heavy casting and forged parts. Measurement only in the
Brinell range up to 650 HB. The requirements on the
surface are not as extensive as with type D.
