Using CryoLab to measure Seebeck coefficients: Video from DEMCON kryoz explains

The Seebeck effect is the direct conversion of temperature differences to electric voltage and vice versa. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference.

By using the CryoLab from DEMCON kryoz, it is possible to measure the Seebeck coefficient of a material sample, wire or thin film from 373 Kelvin down to cryogenic temperatures. In this informative video, DEMCON kryoz demonstrate how such measurements are made using their equipment. For more information, please contact us.

 

 


The “World’s Most Accurate” Capacitance Bridges are from Andeen-Hagerling

Andeen-Hagerling AH2700A Capacitance Bridge Test Instrument

Andeen-Hagerling manufacture the world’s most accurate capacitance bridges and standards, and their AH 2700 models offer unparalleled stability, resolution, linearity and accuracy in a multi-frequency capacitance/loss bridges.
Andeen-Hagerling AH2700A Capacitance Bridge Test Instrument
The numerous state-of-the-art features of the AH2700 make it an exceptionally user-friendly instrument, with unmatched precision that enables it to open up new applications in calibration, manufacturing and scientific research.

The AH2700 is the culmination of over 40 years of Andeen-Hagerling experience in bridge design and manufacture. The unique ratio transformer and the temperature-controlled, fused-silica capacitance standard make the instrument a true bridge for measuring highly accurate capacitance/loss figures which are independent of the exact test frequency (50 Hz – 20 kHz) and immune to mechanical shock.
