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.
Vitreous silica insulation and jacket resists continuous exposure to temperatures up to 1600° F.
Ceramic fiber insulation and jacket withstands continuous exposure to temperatures up to 2200° F.
