Precision and Durability Cu-CuNi Type T Thermocouple Wire for Low Oxidation Tendency
The Cu-CuNi Type T thermocouple wire consists of a pure copper
positive leg (Cu) and a copper-nickel alloy negative leg (CuNi,
typically Constantan). This thermocouple type is well-suited for
precise temperature measurement in the range of -200°C to 370°C (-328°F to 698°F), making it ideal for low-temperature and cryogenic applications.
Type T thermocouples are known for their high accuracy, stability,
and resistance to oxidation, especially in moist or humid
environments. They are widely used in laboratories, cold storage,
cryogenics, and industrial processes that require precise
temperature control at sub-zero temperatures.
These wires also offer good resistance to corrosion and are
compatible with various insulating materials, making them reliable
for both long-term and intermittent use. Their versatility, ease of
calibration, and robust performance make Cu-CuNi Type T
thermocouples a preferred choice for applications demanding
accurate and consistent temperature readings in challenging
environments.
