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 400 K,
and from 200K to 730K. Sample mounting is simple permitting rapid interchange
of samples. SB-100
Seebeck Measurement System is compatible with a variety of computers through
an IEEE-488 (GPIA) or RS-232 interface. The MMR Programmable Seebeck Measurement
System includes the SB-100 Programmable Seebeck controller, the K-20 Programmable
Temperature Controller, the Seebeck Thermal Stage and accessories, a computer
(PC), and MMR supplied software.
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.
