Tru-Blue II Hardness Tester



hardness testerSince 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.
