T- Type Thermocouple
The Type T thermocouple, which has a high level of stability, is frequently employed in cryogenics and other extremely low-temperature applications. It can also be found in other types of laboratories. The reproducibility of type T is very good. The ideal thermocouple for measuring low temperatures is a type T thermocouple. It is utilized in extremely low-temperature applications, such as cryogenics or ultra-low freezers, and is a very stable thermocouple. It consists of a copper wire for the positive leg and a Constantan (Cu & Cu-Ni) alloy wire for the negative leg.
Compared to the alloys often employed in thermocouple fabrication, copper has a substantially higher thermal conductivity in T Type thermocouples. Only copper wire touches the probes in a T-type thermocouple. Since neither conductor is magnetic, there is no Curie point, hence the thermocouples properties do not immediately change.
