How do you make a t type thermocouple?

To make a T-type thermocouple, you need two different conductors: copper and constantan (a copper-nickel alloy). First, cut two wires of each material to the desired length. Then, join the ends of the copper and constantan wires together to form a junction, ensuring a good electrical contact. Finally, insulate the junction with heat-resistant material to protect it from environmental factors while allowing it to accurately measure temperature.
