Bare Thermocouple Wire

Bare thermocouple wire

. Bare thermocouple wire is wire without any insulation. Normally it is sold on a spool and ordered as a pair. Usage is typically for making a small thermocouple in applications requiring special considerations.
. Thermocouples can be created with various combinations of alloys.
. Our thermocouple alloys wire can be used to measure temperatures from 200 °C to higher temperatures up to 1260°C. 4. We offer a wide range of most commonly used thermocouple alloys, type K, J, T, E and N, with diameters 0.2 up to 3.26mm.
