Compressometer/Extensometers

Compressometer/Extensometers are similar to the Compressometer in that they measure average deformation and strain of concrete cylinders during compression testing for determination of modulus of elasticity. In addition, a third center yoke attaches to the specimen to measure horizontal extension. This allows a combined determination of the modulus of elasticity and Poisson’s ratio. A second mechanical dial or digital indicator between yoke segments measures the transverse deformation simultaneously. Mechanical dial indicators measure specimen deformation. Models for 4in (102mm) or 6in (152mm) concrete cylinders are available. Yokes are made of lightweight aluminum, the other parts are cadmium-plated steel.
