2x4in Compressometer/Extensometer for Automatic Compression Machines

Compressometer/Extensometers measure deformation and strain for MOE determinations, plus the horizontal extension of the specimen to calculate Poisson’s Ratio. An additional yoke assembly attached to the test specimen allows the measurement and calculation of both properties. These units integrate with the “MP” versions of our Automatic Compression Machines. The unit (or kit) contains two devices - an averaging Compressometer and an Extensometer.
