Compressometer/Extensometer, Digital Dial Indicator, 4x8in

Compressometer/Extensometer, Digital Dial Indicator, 4x8in

Compressometer/Extensometers are precision instruments designed to measure the average deformation and strain of concrete cylinders during compression testing, providing critical data for determining the modulus of elasticity. These advanced devices go a step further by incorporating a third center yoke, which attaches to the specimen to measure horizontal extension. This unique feature enables the simultaneous determination of both the modulus of elasticity and Poisson’s ratio, offering a comprehensive understanding of the material's behavior under load.

The device includes a second mechanical dial or digital indicator positioned between yoke segments to measure transverse deformation, ensuring accurate and simultaneous readings of vertical and horizontal strain. Mechanical dial indicators or digital variants are used to record deformation data with high precision. Models are available for use with 4in (102mm) or 6in (152mm) concrete cylinders, making them versatile for various testing requirements.

Constructed with lightweight aluminum yokes and cadmium-plated steel components, these instruments are built for durability and ease of use in laboratory environments. Designed to meet ASTM C469/469M standards, they ensure compliance with industry requirements for reliable and repeatable testing.
