Product Description
Diameter 24AWG chromel alumel/Nickel chrome-Nickel silicon/ type K Thermocouple bar alloy Wire for electric insluated cable KP KN (Type K/N/J/T/E) / copper wire
Type K has a better resistance to oxidation than other types of thermocouple (except type N) and is particularly recommended for oxidizing or inert atmospheres.It should not be used without protection in sulphurous atmospheres, in reducing atmospheres or a long time in a vacuum.Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures.
