Epsilon's very high resolution calibrator features 0.8 microinches (20 nanometers) resolution and has 2 inches (50 mm) of measuring range. The 3590VHR calibrator meets the accuracy and resolution requirements for ASTM E83 Class B-1 for 6 mm gauge length and greater extensometers and ISO 9513 Class 0,5 over the full measuring range of the calibrator.
As a result of customer requests, we have interfaced a digital display with the 3590VHR calibrator as an option in lieu of the standard netbook. We have added this display option to our product line to make it available to all of our customers. Additional information is available on the 3590VHR webpage. http://www.epsilontech.com/3590VHR.htm
