A miniature extensometer designed for general purpose transverse or diametral strain measurements on small or thin specimens. May be used simultaneously with the model 3442 miniature axial extensometers or the Model 3542 axial extensometers.

This model clips easily onto the sample with an integral spring to hold the unit in place. It can be adjusted to work on any size sample from 0 to 1 inch (25mm) width or diameter. 

Features:
- May be left on through specimen failure.
- Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.
- All models will measure both positive and negative displacements.
- All standard units have linearity readings of 0.20% or better.
