Since 1984, United has manufactured computer-controlled closed loop Rockwell testers. Our second generation Rockwell 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 one-year indirect calibration for customer specified hardness scales. Along with a user friendly control panel, the tester can be put into operation without the need for an initial 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 becomes portable for use in different departments.
