Compressometer/Extensometer for Concrete Testing

Compressometer/Extensometers are precision instruments designed to measure the average deformation and strain of concrete cylinders during compression testing. These tools are essential for determining the modulus of elasticity and Poisson’s ratio of concrete specimens, providing critical data for material performance evaluation and structural analysis.

Unlike standard compressometers, these advanced models include a third center yoke that attaches to the specimen to measure horizontal extension. This additional feature allows simultaneous measurement of both axial and transverse deformations, enabling a combined determination of the modulus of elasticity and Poisson’s ratio in a single test. The instrument uses either dual mechanical dial indicators or digital indicators to provide accurate readings of both vertical and horizontal strain.

The compressometer/extensometer is available in models for testing 4in (102mm) or 6in (152mm) concrete cylinders, making it versatile for a variety of testing requirements. The yokes are constructed from lightweight aluminum for ease of handling, while other components are made from durable cadmium-plated steel to ensure long-term reliability. This design provides a robust tool that is both lightweight and corrosion-resistant, ideal for rigorous testing environments.
