Digital Electronic Calibrators – Model 3590

  • 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.
    The digital display reads mm and changes to inches at the touch of a button. The autozero button is a great help in calibrating. Just press the button 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. An option is available for digital SPC output for interfacing with PCs. The calibrator is provided with a calibration traceable to NPL (UK standards organization).

  • • Digital display
    • Autozero button simplifies readings
