RMT
Ltd introduces new complex device TEM Expert DX8080
for detailed testing of performance of thermoelectric material
(TEM).
The DX8080 is developed for laboratory testing
of thermoelectric (TE) properties of the n/p-type material based on
Bi2Te3 when measuring pellets.
The tests are performed in vacuum
at a given ambient (sample) temperature.
