Reliable in oxidizing, inert, and dry reducing atmospheres, Ni-Cr vs. Cu-Ni thermocouple wires ensures stable temperature measurement and can endure short-term vacuum exposure. To maintain performance, it should be shielded from sulfur-containing and highly oxidizing environments. Among standardized thermocouples, it delivers the highest electromotive force (EMF) per degree, making it ideal for precise thermal sensing applications.
