Due to its high electromotive force (EMF) output and exceptional sensitivity, this thermocouple wire is suitable for detecting small temperature variations. It offers stable performance even at temperatures as low as 300ºC and provides strong corrosion resistance in humid environments. It’s widely used in oxidizing or inert atmospheres, it should be avoided in reducing environments or those containing sulfur compounds to maintain durability and accuracy.
