Armored Thermocouple Extension Wire with Connectors
Male × Female Flat-Pin Mini Connector
Male × Female Round-Pin Connector
With plug-in connectors on both ends, this wire extends the reach of your thermocouple. It’s protected by a stainless steel armor that also resists corrosion and wear. Made of thermocouple materials, it prevents signal loss.
Choose a wire that matches your thermocouple type. You should also make sure the equipment you're connecting it to is compatible with the same thermocouple type.
