Product Description

 
 

 

Type K NiCr -NiAl Thermocouple Alloy Wire

Product Description

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.
