Overview
Originally developed in 1906, the Chromel/Alumel thermocouple has been globally accepted as the most useful base-metal thermocouple combination. With the standard alloys, or one of several special alloy combinations, it is widely used over a temperature range of -328°F to +2300°F (–200 °C to +1260 °C).
The superior resistance of the alloys to oxidation allows the use of the bare metals throughout the useful range. With proper protection it can be used in almost any environment.
