Description:
These industrial benchtop muffle furnaces have heavy-duty firebrick insulation that surrounds the chamber opening for added durability. Embedded elements in special refractory cement permit excellent heat distribution in the chamber. Adjustable Alarm or Over Temperature Protection (OTP) setting can be used to protect the furnace or loaded chamber from excessive heat. Thermocouple break protection cuts power to the heating elements, prevents a thermocouple failure runaway condition. Choose from two control options: B1: Digital single set point control with a single ramp to set point and a dwell. A single display shows actual temperature or set point. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay. C1: Digital programmable control with one stored program of 8 segments. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay.). Counter-weighted door swings upward, directing heat away from operator. Door safety switch protects operator by removing power to the heating elements upon opening the door. The rear of the chamber incorporates a 0.38" (0.95 cm) diameter port for monitoring chamber temperatures with independent measuring devices. No power cord supplied with 120V models. Electrical connection requires fixed wiring.
