High-Quality Soil uniaxial compression deformation rebound modulus (Poisson's ratio) tester Pricelist, Quotes

The Soil Uniaxial Compression Deformation Rebound Modulus (Poisson's Ratio) Tester measures the uniaxial tensile strength of soil, which is the ultimate normal stress at which a specimen reaches fracture under axial tension alone.
Uniaxial tensile strength is measured by applying progressive axial tension to cylindrical or rectangular specimens until the specimens fracture. It is suitable for clay soils.

Product Description

The Uniaxial Compression Bending-Tension Tester is specifically designed for testing axial forces on specimens under uniaxial compressive stress conditions. It serves as a vital instrument for measuring the unconfined compressive strength of various specimens.

This versatile machine measures flexural strength, axial compressive strength of cylinders, and the static compressive elastic modulus. These measurements provide essential parameters for determining loading standards. The testing process utilizes the standardized three-point compression method to ensure accuracy and repeatability.

Additionally, it is capable of measuring the flexural-tensile rebound modulus under static load using the precise three-point loading method.
