At temperatures above 1500°F (816°C) or in applications where sulfur is present, Type N thermocouple wire provides better repeatability and resistance to oxidation than Type K. The Type N thermocouple wire meets special limits of error from 200 to 2000°F (90 to 1093°C), the nickel-based thermocouple alloy is used in many high temperature applications, including specialty aerospace heat treating. It offers the same accuracy and temperature limits as Type K but has improved repeatability between 700 and 1100°F (370 and 593°C).
