| Thermocouple Probes |
|
Thermocouple probes consist of a tapered wire running through a metal-coated, glass nanopipette. The external metal coating extends over the protruding wire to create a junction across which the voltage drop is temperature dependent. The time response of this thermocouple is orders of magnitude higher than any other thermocouple in existence. Thus, one gains the ability to perform both static and dynamic thermal measurements in very localized regions with high precision.
