Blue M Box Furnace, programmable, with OTC; 208V

Superior temperature uniformity and exceptional reliability|Digital overtemperature control protects from circuit failure|Unique heating elements combined with the Moldatherm fiber insulation and double-walled construction ensure optimum temperature efficiency, fast response, quick heat-up, and rapid cool-down. All models feature PID temperature control. Choose from single-setpoint or a programmable 16-segment control.
Digital overtemperature control (OTC) on select models protects furnace and load from primary control circuit failure. If high limit is reached, it overrides the main controller and shuts off power to furnace. Temperature is monitored by separate thermocouple probe.
Vertical lift door takes up less benchtop space and protects you from the hot inside door surface; a door safety switch cuts off power to the heating elements when the door is open. A 1" dia air vent ventilates the chamber; a 3⁄8" dia atmosphere inlet allows inert gases to be purged.
