The "MODEL RZ2001i" is an evaluation device that automatically measures the thermoelectric power (Seebeck coefficient) and electrical conductivity of thermoelectric conversion materials in high-temperature atmospheres. In thermoelectric measurements, a temperature difference is generated across the sample to measure the thermoelectric power (steady direct current method), and a constant direct current is passed through the sample to measure the conductivity. Please make use of this system developed under the technical guidance of the National Institute of Advanced Industrial Science and Technology's Synergy Material Research Center. 【Features】 ■ Sample temperature can be variably measured (up to 1000°C, 170 steps) ■ Measurements can also be conducted in various atmospheric gases ■ Compatible with prismatic and cylindrical samples ■ Thermoelectric power and electrical conductivity can be measured simultaneously ■ Automatic measurement is possible by simply turning on the switch after setting the sample *For more details, please refer to the catalog or feel free to contact us.
