Application
This SRM is intended to calibrate Seebeck coefficient measurement instruments for bulk materials within the temperature range of 10 K to 390 K.
Features and Benefits
- Accompanied with certified values, obtained using a Quantum designphysical property measurement system (PPMS) through a differential steady-state(DC) technique; an uncertainty analysis was performed following the guidelines outlined in the ISO Guide.
- The NIST certificate is provided with expiration certificate, storage, handling, use, and maintenance instructions.
Other Notes
Please download a current certificate at nist.gov/SRM for current analytes and certified values.
