Compressometer, Mechanical Dial Indicator, 4x8in

Compressometers are precision instruments designed to measure the average deformation and strain of concrete cylinders during compression testing, providing essential data to calculate the modulus of elasticity. These tools are crucial for ensuring concrete quality and performance in construction and material testing.

The compressometer unit includes two lightweight aluminum alloy yokes that securely mount around the concrete specimen. The bottom yoke is rigidly fixed, while the upper yoke is hinged to allow pivoting during testing. A fixed connecting rod, made from durable cadmium-plated steel, links the two yokes, ensuring accurate and stable measurements. The deformation of the specimen is recorded using a mechanical dial gauge or a digital indicator, depending on the model. The mechanical dial gauge provides precise readings, while models with the "D" suffix feature a digital indicator for more convenient, high-accuracy readouts. Both types offer a 0.2in (5.08mm) range and 0.0001in (0.0025mm) divisions for fine measurement resolution.

Compressometers are available in models designed to fit either 4in (102mm) or 6in (152mm) diameter concrete cylinders, making them versatile solutions for a range of testing needs. They are engineered to meet the rigorous requirements of ASTM C469/469M standards, ensuring reliable, standardized results.
