Order this reliable thermocouple wire for use in industrial, research, pharmaceutical, or aerospace applications. Developed using the latest technology, the wire is subjected to a Lengthy Series of electrical, mechanical, and chemical tests—one of the most rigorous quality assurance programs in the thermal instrumentation industry. Wire comes in 30, 24, 20, or 16 gauge for fabricating your own probes or extension cables (meets ANSI and ASTM standards). choose from wire with Polyvinyl Chloride (PVC/PVC), fluorinated ethylene Propylene resin (FEP/FEP), fiberglass (G/G), high-temperature fiberglass (Hg/Hg), or ceramic fiber (CF/CF) outer/inner insulation. PVC/PVC wire is extension-grade wire. Use Spade lugs, mini connectors, or standard connectors to assemble complete probes or extension cables. Order Spade lugs, connectors, and accessories separately. Note: use 30-, 24- and 20-gauge wire with mini connectors or standard connectors; use 16-gauge wire with standard connectors only. G = fiberglass; Hg = high-temperature fiberglass; CF = ceramic fiber make your own thermocouple probes or extension cables high-temperature insulation for use up to 2600°f (1427°c).
