High-Resolution Digital Electronic Calibrators

The very high-resolution calibrator from Epsilon comes with 20 nm (0.8 µin) resolution and features 50 mm (2 in) of measuring range. The 3590VHR is equipped with software to show the calibrator readings and optional digital display or netbook PC.

The 3590VHR calibrator matches the resolution and accuracy requirements for ASTM E83 Class B-1 for a 6 mm gauge length and greater extensometers and ISO 9513 Class 0,5 over the complete measuring range of the calibrator.


  • System completely calibrated traceable to NPL (UK standards organization)
  • Scale calibration traceable to NIST
  • Readings taken on the PC with integrated software can be saved to a data file
  • A foam-lined storage case is provided
  • Same adapters are used as the model 3590 and 3590HR calibrators
  • Software for Windows-based PC provided; a PC with a USB port is necessary
  • Optional Netbook PC or stand-alone digital readout display
