Similar to
the Elcometer 501 and using the same
pencil technique, this motorised device in anodised aluminium
can travel forwards (chip method) or backwards (indentation method)
at a uniform speed - further increasing the reproducibility of
the test.
The load
on the lead is adjustable from 0 to 10N and each instrument is
supplied with a lead holder and a set of 6 leads in each of the
14 hardnesses.
