Axial extensometer 3442AVG series

compactlaser

This all-purpose averaging axial extensometer is used in tension or compression to measure Young’s modulus, offset yield, and strain to failure. It is compact and lightweight. Gauge length is set automatically for fast specimen mounting. 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. The Model 3442AVG is optimized for high-accuracy tension and compression testing. It measures strain simultaneously on opposite sides of the specimen to average out specimen misalgnment while measuring axial strain. The averaging capability is useful for measuring Young’s modulus per ASTM E111, properties of composite materials per ISO 527 and ASTM D3039, and compression of metals per ASTM E9. It is compact, lightweight, and may be used through specimen failure with most materials. It is fatigue rated and may be used in strain control. The extensometer sets its gauge length automatically when it is mounted on the specimen. This feature improves repeatability, reduces operator errors and saves time. Just mount the extensometer and it will be at its gauge length and ready for testing.
