Thermocouples
Thermocouples measure temperature from the voltage generated where two dissimilar metals meet. They cover a very wide range, respond quickly and are robust and inexpensive, which makes them the standard choice for furnaces, boilers, reactors and other high-temperature duties. Types K, J, T, N, R, S and B suit different ranges and atmospheres. Find global manufacturers of thermocouples in our Equipment Guide.
