Affordable bench-top testing solutions
Cost-effective mechanical tester system is designed to test tensile, compression, and flexural properties of rubber, plastic, wire, metals, and fasteners
Capable of applying forces up to 222 kN, the system includes a large mechanical frame, precision dead weights, and a yoke assembly.
The yoke's twin test space offers the flexibility to test either tension or compression load cells, while providing the interface between the dead weights and load cell under test.
The yoke's spherical alignment stops guarantee that it always returns to the same starting position and orientation ensuring repeatable calibrations.
Instron's calibration system provides easy adjustment of the yoke's crosshead to accommodate load cells of different sizes.
Each dead weight has an independently operated elevating mechanism, allowing the weights to be individually applied to or removed from the stack.
The system's unique elevating design features a high accuracy encoder to ensure precise lifting of the dead weight stack.
The design also allows the force of the weights to be carefully applied to the load cell under test.
