100S EXTENSOMETER

The Tinius Olsen model 100S is designed as a dual purpose extensometer to measure E modulus and offset yield stress (proof stress) on relatively high modulus materials while also providing the ability to measure high elongations up to break.

A typical application is the testing of polycarbonate, where a high resolution system is required to measure the E modulus (Youngs modulus) and a secondary system is required to measure elongation to the point of break, which typically could be as high as 200% strain.

Other materials the 100S extensometer is ideally suited to include polyurethane, polyethylene (PET), glass reinforced plastics (GRP), and aluminum alloys.

The unique design ensures an extremely low tracking force for testing sensitive materials and a construction that is sufficiently robust to withstand the release force when the specimen breaks. An important feature is the ease with which the extensometer clamps can be attached to the specimen, resulting in very rapid testing throughput.
