• Patented LGO (light gauge overbend) heating elements with Moldathermâ insulation for efficient and economical transfer of heat to chamber, with low exterior temperatures
• Variable heat-up rate eliminates thermal shock to materials with quick heat-up and cool-down rates
• Choice of side hinge or vertical lift door; see specifications for model selection
• Air vent (1" dia., top) and air inlet (.375" dia., rear) for inert atmosphere exchange
• Self-tuning, digital instrumentation for precise temperature setpoint and display; automatically sets best control parameter values during operation
• Platinel II ® thermocouple for long-term stability
• Main power on/off switch on control panel; control panel designed for easy maintenance access
• Safety door switch to interrupt power to heating element when door is opened; protects heating elements and minimizes exposure to end-user
• Removable shelves for versatility; 0.58 cu.ft. models include 1 two-part shelf, center position; 1.95 cu.ft. models have 3 shelf positions; 1 two-part shelf included standard
• Moldathermâ hearthplate supports loadand prevents damage due to spillage

Digital, Single Setpoint Controller

• Microprocessor-based self-tuning PID control (proportional, integral, derivative) provides optimum thermal process, prevents overshoot
• Single segment, single setpoint, 1 ramp to setpoint
• Adjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint
• May be configured to display temperature in either °C or °F 

Digital 16 Segment, (1) Program Programmable Controller

• Microprocessor-based self-tuning PID control (proportional, integral, derivative) provides optimum thermal process, prevents overshoot 16 segments, 1 program with 8 ramps (up and down) and 8 dwells (timed holds)
• Adjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint
• May be configured to display temperature in either °C or °F

Digital 16 Segment, (4) Program Programmable Controller

• Available on models with "P" designation
• Microprocessor-based self-tuning PID control (proportional, integral, derivative) provides optimum thermal process, prevents overshoot
• 16 segments, 4 programs with 8 ramps (up and down) and 8 dwells (timed holds) eachAdjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint
• May be configured to display temperature in either °C or °F

Overtemperature Control (OTC)

• Adjustable digital overtemperature control, available on selected models with "B" designation; see chart
• Protects furnace and load in the event of primary control circuit failure
• Overrides main controller, assumes temperature control and shuts off power to furnace if high limit is reached
• Manual re-set required for safety
• Operates via magnetic contacts through signal from independent thermocouple 

Flowmeter Option (FM) (Inert Atmosphere Only)

• Available on selected models with ÒFM" designation; see chart
• Gas flowmeter, adjustable, located on front control panel
• Adjustable flow rate, range 1.0 to 10.0 cu.ft./hr standard
• Suitable for inert gas or air flow to chamber
• Allows fresh air exchange for ashing applications
• Not suitable for combustible or volatile gases.
  
  Note: Use with inert atmosphere will exhibit some leakage.
