K Type Thermocouple

Composed of a positive leg of 90 nickel, 10 chromium and a negative leg of 95% nickel, 2% aluminum, 2% manganese and 1% silicon.

Specifications:

When protected by compacted mineral insulation and appropriate outer sheath, type K is useable from -36 to 1260°C, (-32 to 2300°F). If temperature range falls between 316 to 593°C, (600 to 1100°F), we recommend using type J or N because of aging which can cause a drift rate of 1 to 2°C, (2 to 4°F) in a few hours time. For applications below 0C (32°F), special selection of alloys are usually required.
