Frame Capacities & Customisation Options

The Barrus Grey Dual Column Universal Testing Machine is available in the following capacities: 10kN, 20kN, and 50kN.

For the twin-column machines, the higher sizes are also suitable for lower-force testing. For example, a 10 kN frame can still be used for lower-force testing, such as 5 kN or even less.

NB: A wide range of load cells are available for each frame size.

Need an extra size machine, different speed ranges, or maybe a dual workspace in your two-column machine? We understand every testing scenario is unique, which is why all our Barrus Grey models can be meticulously crafted to meet your specific testing requirements.
