Sentry Xpress 4.0 Digital 3-key Ceramics Control Type

Sentry Xpress 4.0 Digital 3-Key Controller with Cone-Fire Mode

We simplify high-temperature firings so you can immerse yourself in creating breathtaking ware. The powerful little Sentry Xpress 4.0 micro processor is packed with features. On ceramic kilns, the controller includes Cone-Fire and 8-segment Ramp-Hold modes to give you amazing flexibility in firing your kiln.

Cone-Fire mode fires your clay and glazes to a pyrometric cone. Simply enter the recommended cone number and a firing speed of Fast, Medium, or Slow. Let the controller do the thinking for you. Ramp-Hold mode lets you program custom firings with up to 8 steps, or segments. Fire exotic glazes such as crystallines, or slow the cooling to enhance certain glazes. Enjoy brilliant colors that were once thought impossible in electric firing. Use Ramp-Hold for glass fusing, bead annealing, and customized ceramic firing.

(Note: Ramp-Hold and Cone-Fire on the Sentry Xpress 4.0 do not include all the features of the Sentry 2.0 12-key.)
