Thermoelectric Conversion Efficiency Evaluation System for Small Modules
Mini-PEM

Measure thermoelectric conversion efficiency for thermoelectric material alone and a pair of thermoelectric material
This system can evaluate not only power generation but also conversion efficiency of thermoelectric modules. The conversion efficiency is evaluated from current dependency of power generation measured with four-probe method and heat flow measured with heat flow meter.
High temperature part can reach up to 500 ℃(standard specifications), while low temperature part is cooled with water flow.

Applications

Evaluation of power generation amount and heat flow.
Evaluation of module conversion efficiency calculated from power generation and heat flow.
Evaluation of power generation amount and heat flow with thermoelectric material alone.
Performance and lifetime evaluation of thermoelectric module.

Features

Capable of measuring data of heat flow and power generation and then measuring conversion efficiency.
Capable of evaluating the output characteristics of small module with 2 to 10 mm (square) x 1 to 20 mm (height).
High temperature part can reach up to 500 ℃.
Simple operation with control software
