Key Features

  • Choice of side hinge or vertical lift door
  • Air vent (1″ dia., top) and air inlet (0.375″ dia., rear) for inert atmosphere exchange (may experience some leakage at door)
  • Self-tuning, digital instrumentation for precise temperature setpoint and display
  • Platinel II™ thermocouple for long-term stability


Microprocessor Control

  • Microprocessor-based self-tuning PID control (proportional, integral, derivative) provides optimum thermal process, prevents overshoot
  • Control panel designed for easy access and maintenance
  • Main power ON/OFF switch on control panel
  • Adjustable high-limit overtemperature protection
  • Simultaneous LED display of actual temperature vs. setpoint
  • Can be configured to display temperature in either °C or °F
  • Safety door switch interrupts power to heating element when door is opened; protects heating elements and minimizes exposure to end-user
  • Removable shelves for versatility
  • Moldatherm™ hearthplate supports load and prevents damage due to spillage


Digital Multiple-Program, Multiple-Segment Programmable Controller

  • Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control


Overtemperature Control (OTC)

  • Protects furnace and load in the event of primary control circuit failure
  • Overrides main controller and shuts off power to furnace if high limit is reached
  • Manual reset required for safety
  • Operates via magnetic contacts through signal from independent thermocouple


Flowmeter Option (FM) (Inert Atmosphere Only)

  • Gas flowmeter, adjustable, located on front control panel
  • Adjustable flowrate, range 1.0 to 10.0 cu. ft./hr. standard
  • Suitable for inert gas or airflow to chamber
  • Allows fresh air exchange for ashing applications Not suitable for combustible or volatile gases
