  • Microprocessor PID control.
  • Temperature calibration / Automatic tuning.
  • Adjustable three-step fan speed with defrosting time and period control.
  • Forced air convection using an optimal cross flow fan for chamber temperature uniformity.
  • Energy efficiency is achieved thanks to optimization of the insulation system. The surface of the unit doesn’t allow high temperatures of over 60℃.


  • Two independently controlled chambers merged into a single unit for space saving.
  • Intuitive control panel with bright LED display (0.1℃resolution) and touch-sensitive keypad.
  • Dual wait on/off timer modes. (1 min. to 99 hr. 59 min.)
  • Convenient preset function for 3 most commonly used temperature settings.
  • Up to 9 temperature steps and maximum 200 cycles of repetition programmable for each profile.
  • Built-in cable port to use other instruments inside the chamber. (diameter: 80mm)
  • RS-232 interface for external control and data collection.
