Tru-Blue II Hardness Tester
Why do the following 5 manufacturers of Rockwell diamond indenters and test blocks trust the TRU-BLUE II to match NIST and UKAS national standards?
✪ David L. Ellis Company
✪ Gilmore Diamond and Tool Company
✪ WESTport Corporation
✪ Star Industrial Tool Ltd
✪ Euro Products Ltd
This level of quality began in 1985 by utilizing a load cell and computer to monitor all required forces in real-time.
Each tester comes with a multi-page “Direct Certification” which lists the calibration of force and depth including uncertainties, a time vs. load curve and the effects of hysteresis. This document gives the user the confidence that the TRU-BLUE II will meet all National and Aerospace requirements.

Published by the National Institute of Standards and Technology, the Recommended Practice Guide, Rockwell Hardness Measurement of Metallic Materials, is essential reading for anyone concerned with hardness testing.
Written by Samuel R. Low of the National Institute of Standards and Technology, this book contains detailed information on everything related to Rockwell Hardness testing, from test procedures to references for test block standards to direct and indirect verifications. This publication resolves several questions including the following:
✪ How often should indirect verification be performed? (Page 54)
✪ Should my hardness tester be “Directly Verified”? (Page 44)
✪ Should machine hysteresis be checked? (Page 45)
✪ How does the test cycle time affect hardness readings? (Page 27)
✪ What about force verification? (Page 45)
✪ What happens if the machine forces are adjusted? (Page 45)

Tru-Blue II Mobile Stand
The mobile floor stand allows the end user to move the tester easily to mulitple locations. Mounting of the tester to the stand is required for safe movement. Setup is performed by disconnecting and re-connecting of the AC power cable. The Tru-Blue II tester is not required to be re-certified, only to be pre-checked on the selected scales to be used.
Note: please see ASTM E18 table A1.1 “Verification schedule for a Rockwell Testing Machine”. The Tru-Blue II is designed to be moved without recalibration!
