1/4" Gauge Thermocoupler Probe - 120 Volt Fiber Kilns - Jen-Ken
This is for 120 volt fiber kilns ONLY. The "K" type thermocouple probe senses the temperature and sends the signal to the controller. Before ordering, look at your probe and make sure it's the same. The ceramic insulators are about 1/4" in diameter with a 4" insulated ceramic bead and 24" cord. This part usually lasts for many years. When it goes bad, you can usually see deterioration inside the ceramic insulators. You can pull them apart to get a look at the length of the probe.
Clean the connection holes and the thermocouple wire ends with fine sandpaper to ensure a snug, clean connection. You can trim down and strip brittle/ scorched thermocouple wire if needed.
