HM-131 and HM-207 series 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 both 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.
HM-131 Series Compressometer/Extensometer is 6x12in.HM-207 Series Compressometer/Extensometer is 4x8in.
