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.

Special Features:

  • Computerized closed loop control of force application

  • In-line depth measurement device and load cell

  • Capable of testing 30 different Rockwell scales

  • 4 X 20 Bright vacuum fluorescent display

  • Statistical summary including average, range, standard deviation, high, low and number of tests

  • Auto correction of hardness values for cylindrical parts

  • Parts clamp used to secure irregularly shaped or oversive parts included

  • Parts IN/OUT of tolerance settings with adjustable audio alert
