1.5 Krautkramer DynaPOCKET
The Krautkramer DynaPOCKET is a handy and easy-
to-use rebound hardness tester enabling the user to
carry out tests quickly and effortlessly.
You can use the DynaPOCKET to carry out measure-
ments anywhere and in any direction; the direction
does not have to be set in advance.
The DynaPOCKET is mainly suitable
❚ for measuring the hardness of low-alloy or unalloyed
steels,
❚ for measuring the hardness of high-alloy steels,
❚ for measuring the hardness of nonferrous metals.
The DynaPOCKET operates according to the rebound
method (according to ASTM standard A 956). In this
method, an impact body is impelled against the test
surface by spring force.
Impact and rebound speeds are measured in non-con-
tact mode and the hardness value is calculated on the
basis of these two measurements. The hardness value
is immediately displayed. Apart from this, a high repro-
ducibility of the test results is ensured.
The DynaPOCKET has only two operating keys to
carry out all functions.
The large display indicates the current single value or
the statistical average of a measurement set, depend-
ing on the selected mode.
