Performance

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

Convenience

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 of 200 cycles of repetition programmable for each profile.
Built-in (Ø 80mm / Ø 3.15") cable port to use other instruments inside the chamber.
RS-232 interface for external control and data collection.
