Allied Wire and Cable stocks a wide variety of Thermocouple Wire, including Type K Thermocouple Wire. Type K Thermocouple is a very popular thermocouple type. It is a general-purpose, inexpensive thermocouple with great temperature precision and a wide temperature range. Type K consists of a positive Chromel wire and a negative Alumel wire. It is the most universal type of thermocouple wire because of its low-cost, accuracy, dependability, and wide temperature range characteristics. Type K Thermocouple Wire is ideal for use in nuclear applications because of its relative radiation stability. Its maximum continuous temperature is around 1,100°C.
