• Digital controllers with high channel density, high capacity and superior configurability

• Rugged, high-performance grips and fixtures


A compression test determines behavior of materials under crushing loads. The specimen is compressed between hardened platens and the deformation at various loads is recorded.

The flexural test measures the mechanical properties of materials when subjected to bending load. A flat rectangular specimen is loaded at 3 or 4 points. Test speed and specimen dimensions are determined by ASTM and ISO standards.

BCO-CDF/ST Series Fully Automatic Hydraulic Combined Compression and Flexture Test Machine is a new design, compact, ergonomic and space saving test solution to perform compression and flexture test in a single machine.


BCO-CDF/ST series compression and bending test machines comes with

• Rigid combined frame

• Hydraulic unit

• 2 x 50 and 1 x 70 mm distance pieces

• 2 channel electronic controller

• Linux based 10 inch industrial LCD display with built in test software

• PC software

• Software user manual
