Thermocouple Wire - Conductor Options

The more common conductors for medical thermocouple use are:

TypePositive LeadNegative LeadComments
TCopper (Cu)Copper-Nickel (CuNi44)Good in moist environments, low temperature and cryogenic applications; highest accuracy, lowest strength
ENickel-Chromium (NiCr10)   Copper-Nickel (CuNi44)Largest EMF µV/°C, greater strength than Type T but better accuracy than Type J and Type K
KNickel-Chromium (NiCr10)Nickel-Aluminum-Silicon (NiMn2Al2Si)
(magnetic)
Largest temperature range, greatest strength at expense of accuracy
JIron (Fe)
(magnetic)
Copper-Nickel (CuNi44)Not suited for low temperature applications
