Small cones and Pyrometric bars are used in the Kiln-Sitter®, a mechanical switch that cuts off power in electric kilns.

Pyrometric Bars are 1 inch (2.54 cm) Long. The uniform shape allows for more consistent control when used in Kiln-Sitter.

Temperature Equivalents use the same numbering system as small cones.
