Thermoelectric Evaluation System

This system can measure Seebeck coefficient and electrical resistivity in the thickness direction and also evaluate the thermoelectric properties on anisotropic materials at the same measurement direction.

Simultaneously measures the Seebeck coefficient and electric conductivity of thermoelectric materials.
Based on requests from both domestic and international academic societies and customers, this system features our easy to use, high-precision measurement techniques. Complies with JIS standards for thermoelectric material Seebeck coefficient measurement equipment.

A series corresponding to special specifications for the properties of various thermoelectric materials and thin films.
A higher level evaluation for various kinds of materials has been required along with the development of thermoelectric materials. This system "Seebeck Coefficient / Electric Resistance. Measuring System ZEM-5 series" is specialized in the features of various kinds of materials such as high temperature, high resistance and thin film, etc. and a performance evaluation system to correspond to various kinds of needs.

The system can evaluate the power generation and heat flow that can be gathered when the temperature difference is given to thermoelectric module in the environment(in atmosphere and under load) and conversion efficiency that can be calculated from maximum power generation and heat flow. In addition, this system can conduct long-hours operation and heat cycle tests of thermoelectric modules and can be used for testing newly developed modules as well as for durability tests under load and temerature in which commercially available modules are actually incorporated.

Property evaluations of thermoelectric generator modules
By applying a maximum 500℃ temperature difference across a thermoelectric generator module, this system finds the thermoelectric conversion rate η by finding the power that is generated P when a one-dimensional heat flow Q is passed through the module.

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.
