Product Description

Bare Wire Thermocouple Chromel Alumel 

 

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.
