Seebeck Coefficient Measuring System

Measures both Seebeck coefficient & electric resistivity


Methuen MA, USA & Yokohama, Japan — Thermal power generation is a method of generating power based on the thermoelectric effect which was discovered by J. T. Seebeck, German physicist in 1821. In the face of recent global warming caused by carbon dioxide and depletion of fossil fuels, thermoelectric conversion devices are attracting attention because of its effective utilization of waste heat energies. It is also the property of electrically conductive materials that enables them to be used as temperature sensors, specifically “thermocouples“.

To meet these pressing requirements, ULVAC-Riko has developed a characteristic evaluating instrument for these materials and devices.

Features

* One unit can be used for simultaneous measurement of both Seebeck coefficient and electric resistance (resistivity).
* The instrument permits measurement of both 6-to-22mm long prism and cylindrical samples.
* The sample holder uses a unique balance contact mechanism, permitting measurement of high reproducibility.
* V-I plot measurement can be made to judge if the lead is in intimate contact with a set sample.
* Measurement is controlled by a computer, permitting automatic measurement with each temperature difference at a specified temperature and elimination of dark electromotive force.
* Measured raw data is saved in text format.

Founded in Japan in 1952, ULVAC is an international corporation that designs, manufacturers and markets equipment and materials for industrial applications of vacuum technology. Today, ULVAC is a leading global supplier of production systems, instrumentation, pumps and vacuum components used in the semiconductor, flat panel display, disk/magnetic media, and industrial manufacturing markets. The corporation is comprised of some 36 individual companies engaged in all sectors of the vacuum industry. The ULVAC name is derived from the company’s conceptual foundation – “The ULtimate in VACuum Technology”.

Combining several business units which had been operating domestically since 1975, ULVAC Technologies, Inc. was established in 1992 as the US subsidiary of ULVAC Japan, Ltd. Headquartered in Methuen, Massachusetts, ULVAC Technologies provides sales and service to the North American market for all ULVAC products. In addition, this facility is equipped with a class-10 cleanroom for process development, customer demonstration and manufacturing of the ENVIRO solvent-free dry photoresist stripper.
