With official calibration certificates UKAS, DKD or ASTM.
CV Instruments offers a wide range of indenters. All certified indenters
will be issued with a certificate traceable to internationally recognised
standards such as UKAS, DKD or ASTM. We also offer low cost factory
certified indenters and specials (see below).
CV Instruments also offer special adapters for indenters to enlarge
the field of application. Small gooseneck adapters are available in
three sizes to permit regular or superficial Rockwell hardness testers
to perform internal tests on rings, tubes and annular parts where the
inside diameter, plus the wall thickness, is less than 50.8mm or 2".
These adapters will fit any of the standard Rockwell hardness testers.
The gooseneck adapter can be clamped into the bottom of the plunger
rod (in the same manner as an indenter) and is not heavy enough to
affect a reading due to increasing the applied load. The minimum
internal diameter which can be tested is 11.5mm or 7/16".
