Model 3442 Miniature Extensometers
Very small, rugged, yet ultra-light weight. These units are widely used for testing small and delicate samples. Ideal for many biomedical tests, as well as for wire and thin sheet materials. Also great for cycle fatigue testing where short samples are used.

Model 3800 High Elongation
Extensometers
Designed for plastics, rubbers, and elastomer testing, these extensometers have very long measuring ranges. Their unique design allows testing to failure and minimizes interaction with the sample.

Laser Extensometers
These extensometers are high precision non-contacting units for strain measurement in materials testing. They use a high speed laser scanner to measure the spacing between reflective tape strips on the sample.
