The LCR-500 system provides labs with load-cell Rockwell-type testing for greater flexibility in materials characterization. Using closed loop, self-compensating load-cell technology, the LCR-500 also allows user selection of a minor/major load combination (3 to 200 kg). Operator control over the entire test cycle is possible, allowing various test parameters to be easily configured. Minor load application speed and dwell time, major load application speed and dwell time, and final force (hold) time selections enable users to duplicate or modify the test cycle times developed by NIST for calibrating NIST Rockwell Hardness Standard Reference Materials.
