Furnace features a counter-weighted door that swings upward to direct heat away from operator. Four separate embedded heating elements in special refractory cement provide uniform heat distribution in the 136 cu. in. capacity chamber over a range of 100° to 1200°C. Chamber measures 9” D x 3.75” H x 4” W. Digital single setpoint control with a single ramp to setpoint and a dwell has a single display that shows actual temperature or setpoint.  Door safety switch provides operator protection by cutting power to heating elements when door is opened. Thermocouple break protection cuts power to heating elements to prevent thermal runaway condition. Furnace also utilizes a mechanical Over Temperature Protection relay. Power cord is not supplied with 120V model as electrical connection requires fixed wiring.
