Tru-Blue II

   The Tru-Blue II is a digital twin Rockwell hardness tester that utilizes a closed loop load cell system.  The closed loop load cell system has two main components.  A glass scale is used to measure the depth of penetration and a load cell is used to verify the correct force is being applied. 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 the optional mobile stand, the Tru-Blue II becomes portable for use in different departments.


      The Tru-Blue II comes standard with a Direct force certification of the hardware calibration with NIST traceability and a factory one-year indirect calibration for customer specified hardness testing scales.
