Model
HRD-150 Rockweli
Motor-Driven Hardness Testerl
Features:
A frictionless
loading shaft mechanism is adopted in
the instrument instead of conventional
type. As a result, the accuracy of preliminary
test force has been greatly increased.
A unique automatic
zeroing dial gauge is incorpo-rated
in this instrument for measuring the
depth of indentation so as to eliminate
the human error in the procedure of
zero setting.
A series of
operations involving applying, holding
and releasing of total test force is
performed auto-matically. That thoroughly
eliminates human error in those operations.
