Series 3575 Extensometers are designed for general purpose transverse or diametral strain measurement on axially loaded specimens.

Self-supporting on test sample, these Extensometers will work on any width or diameter specimen from 0 to 1 inch (25mm).Commonly used for measurement of Poisson's ratio, for transverse measurements with anisotropic materials like many composites and for sheet metal testing. All models will measure both positive and negative displacements.

Meets ASTM E-83 class B-1 and ISO 9513 class 0.5 requirements for accuracy. Measuring range: 0.075 inches or 2 mm (specify). Easy to mount, with integral springs to keep the extensometer on the sample.
