Z-meters
-
-
RMT produces Z-Meters - devices for fast diagnostics of performance and reliability parameters of TE modules.
The RMT's 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 are to 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 are resulted 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.
