WHY PROTECTED THERMOCOUPLES?

• The Protection Tube extends past the tip, protecting the tip from damage while loading the kiln

• Keeps the oxide dust from the thermocouple tip from getting into the kiln while firing.
  (Any dust should still be vacuumed when doing the normal cleaning of the kiln).

• Protects thermocouples from excessive radiation error from the nearby hot elements.

• Reduces zone control errors because the tips of all thermocouples are equally exposed to the heat of the kiln while still being as protected as possible.

Size and Description

• The protection tubes are 3/4” in outside diameter with a 1/2” inside diameter (which accommodates the standard 8 gauge Type K thermocouple).

• There is a flange on the back end of the thermocouple to prevent it from going into the kiln.

• The tube is open but protrudes past the delicate tip of the thermocouple.

Calibrating the Kiln

• For ceramic work we recommend calibrating the kiln performance with cones and adjusting the control to match the performance of the firing cones. The most important thing is to get a consistent reading from the thermocouples.
