The 3590VHR from Epsilon consists of good resolution, digital electronic calibrators. The unit features a 0.8 microinches, or 20 nanometers, resolution, and is equipped with 2 inches or 50 mm of measuring range.
The 3590VHR is offered with a netbook PC and software to indicate the calibrator readings. The calibrator matches the accuracy and resolution standards for ASTM E83 Class B-1 for a 6-mm gauge length and greater extensometers, and ISO 9513 Class 0,5 over the full measuring range of the calibrator.
It uses a rough adjustment screw for huge displacements, combined with a fine adjustment screw that enables fine adjustment to within approximately 0.025 microns, or about 1 micro inch.
When it is time to calibrate the extensometers, these calibrators are easy to use and quick.
