The 3590VHR uses a coarse adjustment screw for large displacements, coupled with a fine adjustment screw that allows fine adjustment to within approximately 0.025 microns (about 1 micro inch). When it comes time to calibrate your extensometers, these calibrators are easier to use and faster than any others on the market. They have enough measuring range to calibrate nearly all extensometers, and enough resolution to calibrate units with low measuring ranges.
The software provided reads in both inches and millimeters. The autozero function is a great help in calibrating. Just activate it to start readings from zero. The digital display reduces operator error.
A wide range of adapters are available. The calibrator comes with smooth round adapters of 9.52 mm diameter (0.375 inches). For special adapters, contact Epsilon. For very long gauge length extensometers, an optional extension post is available. The calibrator is provided with a calibration traceable to NPL (UK standards organization).
• Scale calibration traceable to NIST.
• System fully calibrated traceable to NPL (UK standards organization).
• Software for Windows based PC provided, a PC with a USB port is required.
• Readings taken on the PC with included software may be save to a data file.
• Uses the same adapters as the model 3590 and 3590HR calibrators.
• Provided with a foam lined case for storage.
• Optional Netbook PC or stand-alone digital readout display.
