This unit is commonly used for measurement of Poisson's ratio, for transverse measurements with anisotropic materials like many composites and for sheet metal testing such as r-value determination.
The unit can be well suited to use along with the axial extensometer 3542.
The Model 3575 extensometer can be easily attached to the sample and its round contact edges can hold the specimen in one position. It is positioned in a place by means of an integral spring.
These units are high accuracy strain gaged devices that are compatible with any electronics suitable for strain Single lateral measurement is widely being used for various tests instead of the traditional three manual measurement methods. The Model 3575AVG is an alternative unit performing dual lateral measurements to average the transverse readings from two locations.

Key Features

• May be left on through specimen failure

• Usable with wide range of specimen sized up to 25 mm

• Accurate stain gaged unit (full bridge, 350 ohm) with linearity 0.2% or better

• All models will measure both positive and negative displacements.

• Easy to mount, with integral springs to keep the extensometer on the sample.

• Self-supporting on specimen

• Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs, this also allows cyclic testing at higher frequencies.

• Easy to operate and comfortable clamping

• Includes high quality foam lined case
