Z-Meters - devices for examination of performance and reliability parameters of TE modules. Z-Meters have extended capabilities, many useful functions for fast and accurate testing of various types of thermoelectric modules.

The following parameters of thermoelectric modules can be measured:

•  
  • AC Resistance (R) 
  • Thermoelectric Figure-of-Merit (Z) 
  • Maximum Temperature Difference (dTmax)
  • Time Constant of TE Modules (t)

The Z parameter and dTmax result from  Harman method concept. Advanced technique developed in RMT allows precise characterization of single-stage and two-stage TE modules, measurement of AC resistance and time constant in a wide range.
Additionally, it is possible to evaluate quality of three or more-stage TE modules by the measurement of electrical resistance and time constant.
