RMT Ltd introduces new complex device TEC Expert DX8020 for detailed examining of thermoelectric cooling modules, measurement of their various performance parameters 

The DX8020 provides automatic capability to measure full specifications of a TE module at one measuring cycle in given ambient conditions.


FEATURES

bullet

DTmax, Qmax, Imax, Umax in a temperature range 

bullet

TEC operation at different heat loads to cold side and to middle stages (multistage TECs) 

bullet

Imitation of TEC operation in different applications 

bullet

AC Resistance,  Figure-of-Merit and Time Constant in a temperature range

bullet

Performance of TE Material (Seebeck constant a=ƒ(T), conductivity s=ƒ(T) )


The DX80200 is intended for acceptance, qualification and research testing of TE modules.
