Model No. 900-345
Just like our Phase II analog Rockwell Hardness
Tester, the 900-345 Superficial Rockwell
Hardness Tester comprises "state of
the art" design and dynamic precision
only found at Phase II. Used for testing
thin and soft material in the Superficial
Rockwell Hardness scales, this hardness tester
is ruggedly engineered to obtain highly sensitive
and accurate readings. Conforming to ASTM
E-18 Superficial Rockwell Hardness standards,
this hardness tester will offer unmatched
repeatability in all Superficial Rockwell
Hardness scales (table shown below). A perfect
performer suited for any environment including
heat treat facilities, tool rooms, workshops,
laboratories and inspection labs. Lifetime
technical support is included with all Phase
II Hardness Testers. So test away with confidence
and a level of accuracy you will only find
at Phase II.
