The 900-331 Rockwell scale hardness tester is easy to operate, yet engineered to obtain highly sensitive and accurate readings. Conforming to ASTM E-18 Rockwell Hardness standards, the 900-331 tester will offer unmatched repeatability in all standard Rockwell Hardness scales (table shown below). A perfect, rugged performer suited for any environment including heat treat facilities, tool rooms, workshops, laboratories and inspection labs. Lifetime technical support is included on all Phase II Hardness Testers. So test away with confidence and a level of accuracy you will only find at Phase II.

Tru-Blue II Hardness Tester

Since 1984, United has manufactured computer-controlled closed loop Hardness testers. Our second generation Hardness tester, the Tru-Blue II is the lowest priced US manufactured closed loop tester that meets ASTM E18, ISO 6508 specifications and NIST recommendations.

The Tru-Blue II comes standard with a Direct certification of the hardware calibration with NIST traceability and a factory one-year indirect calibration for customer specified hardness testing scales. The tester can be put into operation without the need for an additional on-site calibration or manufacturers assistance!

Having no dead weights, pivot points and knife edges to move out of adjustment, the Tru-Blue II can be moved to a new location without having to be re-calibrated. When mounted on United's optional mobile stand, the Tru-Blue II is transportable to different locations.
