These rugged highly efficient box furnaces will provide the long-life performance required in todays laboratory settings. Ideal for multiple heat treating applications.
Specifications: Hard refractories around the chamber entrance and chamber floor provide durable long-life materials for these wearing surfaces. A heavy gauge heating element with unique graded element winding, and an insulating front vestibule enhances chamber uniformity. Operator safety is enhanced through double shell construction producing low temperature outer case, a positive break safety door switch that cuts power when door is opened, and an easy to operate upward opening door that keeps the hot face away from the operator. Furnace chamber is equipped with a chimney vent for process exhaust. The furnace control reference is a long-life Type R thermocouple. Furnace temperature controller is a highly accurate 8 segment programmable control. Each segment may be either a ramp (up or down) or a dwell (timed soak). This PID instrument incorporates two LED digital displays that simultaneously indicate actual furnace temperature and set point temperature. Temperature may be displayed in degrees C or F. Programmable temperature control. 3100 Watt, 208/220V.
