We offer Z-Meters - devices for examination of performance and reliability parameters of thermoelectric cooler, developed by RMT company.  The RMT's Z-Meters have extended capabilities, many useful functions for fast and accurate testing of various types of thermoelectric coolers.

The following parameters of thermoelectric coolers can be measured:

1. ‣AC Resistance (R) 
   

2. ‣Thermoelectric Figure-of-Merit (Z) 
   

3. ‣Maximum Temperature Difference (dTmax)
   

4. ‣Time Constant of TE Coolers (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 coolers, measurement of AC resistance and time constant in a wide range.
Additionally, it is possible to evaluate quality of three or more-stage TE coolers by the measurement of electrical resistance and time constant.
