The F47900 models provide 2 L of heating areas while the F48000 models provide 5 L of heating area. A hearth tray in included. The F48000 models also include a ceramic shelf that doubles furnace load capacity.

Choice of Temperature Controllers:
• A1: Digital single setpoint cointrol; single display shows actual temperature of setpoint
• B1: Digital single setpoint control with single ramp to setpoint and a dwell; single display shows actual temperature or setpoint; mechanical over-temperature protection relay is included
• C1: Digital programmable control with one stored program of 8 segments; mechanical over-temperature protection relay is included

• Reaches a 1200°C maximum temperature
• Built-in vent port removes contaminants and moisture
• For added protection, the door safety switch stops power to heating elements when door opens
• Thermocouple break protection cuts power to heating elements, preventing a thermocouple failure runaway condition
• Two open coil heating elements on chamber sides assure fast heat-up with minimum temperature gradient
• Thermal-efficient ceramic insulation surrounds chamber for maximum energy efficiency
• 0.95 cm (0.38 in.) dia. port for monitoring chamber temperature with independent measuring device at rear of chamber
