The Cress E-Series electronic kiln features the most advanced electronic control on the market.It provides 5 (rather than 3) preset easy-to-use firing speeds, plus available custom programming capability, for an almost infinitely flexible range of firing profiles.Most−E series kilns now have 3-zone capable controls, but are initially connected up for one zone.This keeps maintenance to a minimum using one thermocouple instead of three.Temperature uniformity is superb by design and not brute force.Three-zone temperature controls may be ordered at additional cost at the time order is placed.
