A new thermal conductivity probe, 45 mm long and 300 m in diameter has been designed, built, calibrated and tested. It is particularly suited to carry out measurements on special materials, difficult to be purchased in large quantity or available in small sizes. In fact, because of its small diameter, samples as small as 30 mm thick can be measured. This is for example the case of HTTS (High Temperature Transition Superconductor), or ceramic components of fuel cells. Another possible application is the measurements of thermophysical properties ( thermal conductivity, heat capacity, methabolism and blood perfusion) of living tissues, because, being so thin, its insertion can be considered quasi non invasive. First tests showed good performances of the probe, and a total uncertainty of about 1.5 % has been obtained.

Abstract
A new thermal conductivity probe, 45 mm long and 300 m in diameter has been designed, built, calibrated and tested. It is particularly suited to carry out measurements on special materials, difficult to be purchased in large quantity or available in small sizes. In fact, because of its small diameter, samples as small as 30 mm thick can be measured. This is for example the case of HTTS (High Temperature Transition Superconductor), or ceramic components of fuel cells. Another possible application is the measurements of thermophysical properties ( thermal conductivity, heat capacity, methabolism and blood perfusion) of living tissues, because, being so thin, its insertion can be considered quasi non invasive. First tests showed good performances of the probe, and a total uncertainty of about 1.5 % has been obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
