Digital Electronic Calibrators – Model 3590

Epsilon’s standard calibrator features 0.001 mm (50 microinches) resolution and has 50 mm (2 inches) of measuring range. The autozero button and digital display greatly simplify calibration of extensometers. The 3590 calibrator is useful for extensometer calibration and verification with test systems.

38 EXTENSOMETER MODELS are available in many thousands of variations. Our focus on helping customers has led to the development of models to cover nearly any test method.

Operation of these, and all of Epsilon’s extensometers, are

VERIFIED TO APPLICABLE STANDARDS SUCH AS ASTM E83 OR ISO 9513

using in-house calibration systems that are calibrated with Epsilon’s laser interferometer system.

WITH EPSILON’S 20+ YEAR HISTORY OF SERVICE

to the materials testing community, you know we will be there to stand behind our products when your critical application requires it.

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 round adapters (9.52 mm [0.375 inches] diameter) that work with many typical axial extensometers. Specialized adapters are available. For very long gauge length extensometers, optional extension posts are 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).

With Epsilon’s in-house laser interferometer system, the full calibrator system can be calibrated traceable to NPL. No longer do customers have to rely on micrometer head only or potentially error-prone gauge block calibrations for full system calibrations.

Model Number:

3590

 
Standards Labs in most countries have signed a Mutual Recognition Arrangement CIPM MRA. This includes the NPL in the UK, NIST in the USA and many others. This makes them effectively traceable to each other. Services of the NPL are equivalent to those offered by NIST and are recognized by NIST through this agreement of reciprocity.
