Type T thermocouples (copper-constantan thermocouples) are best suited for measuring medium to low temperatures ranging from -200℃ to +350℃. Their biggest advantages are high accuracy and stability at low temperatures, and because the positive electrode is pure copper, it is non-magnetic and will not interfere with the magnetic field environment. However, because the positive electrode is copper, it is prone to oxidation at high temperatures, so it must never be used in high-temperature applications exceeding 350℃.
