Oct. 27, 2014 – Watlow’s “N” Type thermocouple wire is designed to provide superior repeatability and resistance to oxidation over “K” Type wires at high temperatures (1,500 degrees F and above), or in applications where sulphur is present, the company says. Watlow’s Type N thermocouple wire meets special limits of error from 200 to 2,000 degrees F. This nickel-based thermocouple alloy is used in many high-temperature heat-treating applications, including specialty aerospace heat treating. It offers the same accuracy and temperature limits as Type K, but has improved repeatability between 700 and 1,100 degrees F (370 and 593 degrees C), according to the company.
