ToniPRAX is a single-purpose compression test system for cement and mortar specimens. It uses a low-friction hydraulic drive with the digital measuring cell installed directly in the flux of the force for maximum measurement accuracy. The closed-loop servo-controlled valves are operated digitally through ToniTROL measurement and control system. Like ToniNORM, ToniPRAX features automatically controlled preprogrammed test procedures. The compression system is designed for low-load compression tests on standardized specimen 40 x 40 x 160 mm3 prisms or 2” cubes according to the appropriate standard as listed above. The standard model allows for a maximum test load of 250 kN (56,800 lbs).

ToniPRAX can be configured not only for standard specimen compression testing, but also 3-point bending tests for prism specimens. A 3-point bending fixture is used. One end of the bending bridge has a fixed position while the other is adjustable and tilt-mounted. The bending edges are directly linked to the digital measuring cell to assure maximum measurement accuracy.
