Thermocouple Wire

Solid Thermocouple Wire

Stranded Thermocouple Wire

Make your own thermocouples.

Stranded wire is more flexible than solid wire.

FEP insulation and jacket is abrasion and chemical resistant.

Fiberglass insulation and jacket is rated for higher temperatures than FEP and is highly chemical resistant.

Polyimide insulation and jacket stands up to humid conditions and rapid temperature changes.
