Thermocouple Connectors
Simplify connecting your thermocouple to thermometers and control panels—these connectors give your thermocouple a plug-in connection. To attach them to your thermocouple, first remove the panel on these connectors to expose the terminals. Then insert your thermocouple wire leads, tighten the terminals, and reattach the panel.
