The Model 3742 clip-on extensometer is designed for fast mounting and high testing efficiency. It is ideal for laboratories that require frequent specimen and gauge length changes, reduced setup time, and consistent, repeatable strain measurements. The 3742 is applicable for testing a wide range of materials, including metals, plastics, composites, and ceramics, in both tension and compression.
This model sets the gauge length automatically as the extensometer is mounted on the specimen. Gauge length pins are not required. Gauge lengths can be changed in seconds, without tools, using the 3742’s new Quick Swap gauge length system, and fine adjustments can be made to ensure that the gauge length remains within tolerance. Clamping force is easily adjusted without tools.
The Model 3742 includes Epsilon’s quick attach kit as a standard feature, allowing the extensometer to be mounted quickly and easily.
Model 3742 extensometers are applicable for testing in accordance with the following standards:
- ISO 6892-1, 527-2, 527-4, 527-5, 10113
- ASTM E8, E9, D3039, D638, A370, D3552, E517, E646
