The Model 50ST is engineered to perform tension, compression, flexure, and shear strength testing across a wide range of materials and assemblies. Its single-column structure provides a compact and cost-effective platform, combining durability with precision through the use of high-quality components.
Load cells in multiple capacities are available to deliver accurate force readings, whether working with small specimens or approaching the system’s full load range. When paired with specimen grips, strain measurement tools, and Tinius Olsen’s Horizon software, the Model 50ST becomes a versatile and complete testing solution.
Features and Benefits
- The system supports tests up to 50 kN (11,000 lbf) for applications in tension, compression, shear, flexure, and more.
- Its single-column design allows for compact, economical setup and straightforward operation.
- Users can select from several control interface options: a tethered handheld unit, a wireless Bluetooth interface panel, or a virtual machine controller.
- All interface types are fully compatible with Horizon data analysis software.
- It complies with—or exceeds—the requirements of global materials testing standards.
- Four full-length T-slots are integrated into the column to accommodate secure accessory mounting.
- Built-in pneumatic distribution ports provide local air supply to pneumatic grips

Options and Accessories
- Grips and fixtures can be easily mounted securely with a simple locking pin, which also allows simple and rapid changes.
- Furnaces and environmental chambers can be installed for tests at high or low temperatures.
- Tinius Olsen’s Horizon software can be connected to the tester by the operator.
- Full range of precision extensometers and deflectometers are available using video, laser, encoder, strain gauge, and/or LVDT technologies.
- Safety enclosures with interlocks can be installed to protect operators from violent specimen breaks.
- Test frame can be extended by up to 400 mm/16 in to increase test area size.
