  • Uses the same adapters as the model 3590 and 3590HR calibrators;
  • Provided with a foam lined case for storage;
  • Comes with 9.5 mm diameter round posts for extensometer attachment;
  • Includes ISO 17025 accredited NPL (UK) traceable calibration certificate for the full calibrator stand.
  • 3590-02 Adapters for flat specimens
  • 3590-03 Adapters for clip-on fracture mechanics gauges
  • 3590-04 Transverse extensometer adapters

*Note: ISO527 requires 1 micron accuracy extensometer.

Calibrator resolution should be better by at least a factor of two.

ASTM E399 requires 20 uin resolution
