Seebeck Measurement Systems

Description

MMR's Seebeck Measurement System allows users to make automatic measurements of the temperature-dependent Seebeck potential of metals, semiconductors and other electrically conductive samples over a temperature range from 70 K to 730 K, and from 300K to 730K. Sample mounting is simple permitting rapid interchange of samples. The Seebeck system is compatible with a variety of computers through a USB or RS-232 interface. The MMR Programmable Seebeck Measurement System includes the SB000 Digital Seebeck Controller, the K2000 Digital Temperature Controller, the Seebeck Thermal Stage and accessories, and MMR Technologies Integrated Software Suite.

The Seebeck Thermal Stage includes two pairs of thermocouples. One pair is formed of junctions of copper and a reference material of known Seebeck emf. The other pair is formed of junctions of copper and the material whose Seebeck emf is to be determined. The system uses a sophisticated parametric double reference measurement technique developed at MMR Technologies, that yields precise, highly reproducible results, even with difficult samples.
