ULVAC-RIKO
ZEM Series Thermoelectric Characteristics Evaluation Instrument

- For measurement of Seebeck coefficient and electric conductivity of thermoelectric materials -

This instrument is designed for simultaneous measurement of Seebeck coefficient and electric conductivity of thermoelectric materials.
●Application

1. Evaluation of thermoelectric characteristics of a wide range of materials, including semiconductors, ceramics and metals
●Features

1. Employment of an infrared gold image heating furnace that excels in temperature controllability and a micrometer for controlling temperature difference.
2. Measurement is made at each temperature gradient at a specified temperature controlled by a computer, allowing automatic measurement by eliminating dark electromotive force.
3. V-1 plot is provided as standard for checking contact of the sample and lead.
