  • LED display simultaneously shows both setpoint and actual furnace temperatures in °C or °F
  • User-selectable overtemperature protection
  • Open thermocouple protection
  • Adjustable power output from 1 to 100%

Safety and Design Features

  • Heating elements are on 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 chamber incorporates a 0.95cm (0.38in.) diameter port for monitoring chamber temperatures with independent measuring devices
  • Critical electronic components and heating elements are protected by a 35A circuit breaker
  • Door safety switch stops power to the heating elements when door open

Choice of Temperature Controllers

  • Furnaces that use B1, C1 or D1 control also use a mechanical Overtemperature Protection relay
  • B1: Digital single setpoint control with a single ramp to setpoint and dwell; single display shows actual temperature or setpoint
  • C1: Digital programmable control with one stored program of 8 segments
  • D1: Digital programmable control with 4 stored programs, 16 segments per program, and RS-232 communications interface
