Heating & Cooling Chambers

Code:

Heating & Cooling Chambers

-20℃ to 100℃ (H flow)

Performance

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℃.

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 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.

Safety

Automatic shut off after overheat alarm.
