Large Muffle Oven

Robust design and choice of four temperature controllers, ideal for industrial applications including ashing organic and inorganic samples and conducting gravimetric analysis.
 

• Heating elements are located on top, bottom, and sides of chamber for enhanced temperature uniformity.
• Spacious 14L (0.5 cu. ft.) capacity and reaches a maximum of 1200°C
• Four heating elements are located on the chamber top, bottom and sides for enhanced temperature uniformity
• Built-in vent port removes undesirable contaminants and moisture to extend the life of the element and unit
• Rear of the chamber incorporates a 0.312 in. diameter port for monitoring chamber temperatures with independent measuring devices
• Optional stainless-steel shelf doubles load capacity (maximum temperature of 900°C)
• Door safety switch stops power to heating elements when door opens
• Thermocouple break protection cuts power to the heating elements, preventing a thermocouple failure runaway condition
• Furnaces with B1, C1, and D1 control also use a mechanical over-temperature protection relay
   

Choice of Temperature Controllers
 

• A1: Digital single setpoint control; single display shows actual temperature or setpoint
• B1: Digital single setpoint control with single ramp to setpoint and a dwell; single display shows actual temperature or setpoint
• C1: Digital programmable control with one stored program of eight segments
• D1: Digital programmable control with four stored programs, 16 segments per program and Controller includes RS-232 communications

Operations:

Four temperature controller models: Control A1) Digital single set point control. A single display shows Actual temperature or set point. Control 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. Control 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. Control D1) Digital programmable control with 4 stored programs, 16 segments per program. The controller also includes RS232 communications. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay.
