The TMA 2940 can perform experiments on
several different types of samples using both
standard and optional accessories.
The accessory kit supplied with the TMA 2940
contains weights, sample holder (stage), a hex
wrench, tweezers, samples for calibration, and
standard probes.
The standard probes (see Figure 1.3) allow you
to perform various basic analyses. These probes
include the following:
• The expansion probes are used to measure
the thermal coefficient of expansion and
glass transition. The standard expansion
probe is used for routine samples. The
macro expansion probe covers a larger area
of the sample surface and is therefore able
to give a more representative reading for
samples such as powders, materials with
uneven surfaces, frozen liquids, and films.
• The penetration probe has a small tip that
permits it to sink into the material as it is
heated, and is used to measure softening and
melting points.
