Model 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 for 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.
