Type T thermocouple is the best thermocouple to measure low temperature. It is very stable thermocouple and is used in extremely low temperature applications such as cryogenics or ultra low freezers. It consist of positive leg made of an Copper wire and negative leg made of Constantan (Cu & Cu-Ni) alloy wire.
In T Type thermocouple copper has a much higher thermal conductivity than the alloys which are generally used in thermocouple construction. In T Type thermocouple only copper wire touches the probes. As we know both conductors are non-magnetic, there is no Curie point due to which there is no immediate change in characteristics of the thermocouple. Type T thermocouples have a sensitivity of about 43 µV/°C.
