Model No. 900-360

The Phase II Digital Rockwell Hardness Tester adopts a micro computer controller to fully automate testing procedures and achieve a level of dynamic precision that is only found at Phase II. This  state of the art Hardness Tester offers programmable scale conversions, dwell times, statistical capabilities and test counter. Conforming to ASTM E-18 Rockwell Hardness Standards, this hardness tester presents unmatched repeatability in all Rockwell Hardness scales (see table below). The 900-360 is easy to operate, yet engineered to obtain highly sensitive and extremely accurate readings. 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.

  • Fully automated testing procedures affords highly sensitive and accurate readings
  • Micro computer controlled with output to supplied mini printer
  • Offers programmable scale conversions, dwell times, statistical capabilities and test counter
  • Capable of testing in all of the regular Rockwell® scales
