SBA 458 Nemesis ® Simultaneous determination of Seebeck coefficient and conductivity
SBA 458 Nemesis ® Simultaneous determination of Seebeck coefficient and conductivity
Product details
SBA 458 is a Seebeck coefficient measuring instrument developed by the German company Nike specifically for the field of thermoelectric materials, which can accurately measure the Seebeck coefficient and conductivity of thermoelectric materials. SBA 458 adopts a special vertical top loading structure, which greatly reduces sample preparation requirements while ensuring measurement accuracy. The measurement operation is more convenient and reliable.
NETZSCH SBA features:
• Unique measurement mode, supporting more sample sizes, with a maximum temperature of 1100 ° C
Vertical top mounted sample, easy sample replacement, more reliable contact between sample and sensor, compatible with multiple sample shapes
Unique dual heater system that can alternate heating at both ends of the sample, capable of monitoring phenomena such as uneven sample distribution
The thermocouple is fixed in position and has a preset contact force, which can prevent the sample or thermocouple from sliding. The thermocouple is equipped with a sheath to prevent adhesion with the sample.
No need to measure thermocouple distance, eliminate potential sources of error, improve the accuracy and repeatability of test results

SBA 458- Software Features
The SBA 458 software consists of two parts: testing software and analysis software, running on Windows 7 and Windows 10, 32-bit or 64 bit platforms. It can control the testing to be conducted within the set temperature range, making it easy to operate and process the data.
The main functions of measurement software are:
Edit measurement parameters (can include temperature steps of any segment)
Pre testing at room temperature (quality inspection)
Perform measurements according to the set temperature program.
Can simultaneously test conductivity and Seebeck coefficient, or choose to test one of the two.

The main functions of analysis software are:
Viewing Seebeck coefficient and resistivity curves
• Comparing multiple curves
• View the quality control curve separately for each temperature point
Delete test results for certain temperature points
• Modify sample size and recalculate conductivity
Fitting Seebeck coefficient and conductivity curve, importing LFA thermal conductivity data, and finally calculating ZT value
Export of various types of data and graphs
