Load Cells

Load cells convert the force experienced by the specimen into an electrical signal that is used by the electronic controller to precisely monitor, report or control the force.


Extensometry provides a direct and accurate method for measuring and controlling specimen deformation by monitoring strain over a precisely defined gauge length.

Chambers and Furnaces

Environmental chambers and furnaces provide the capability to study the mechanical properties of materials and components over a wide range of temperatures up to +1600 °C in air.

Tensile Grips

Various styles of tensile grips at different force capacities to hold a diverse range of materials such as thread, rope, rubber, plastic, composites, fasteners, steel and more.

Compression Platens

Compression platens and anvils are available in a range of sizes and force capacities to suit applications from rigid foam to concrete.

Flex Fixtures

Flexure or bend tests are widely used to determine stiffness and yield properties of plastics, metals and similar rigid materials.

Peel, Friction, Puncture

Fixtures for Universal Testing Machines to perform an assortment of peel, puncture, burst, and coefficient of friction tests.

Frame Accessories
