Heating & Cooling Chambers (LCH)

-20℃ to 100℃ (H flow)

with optional recorder

Model Name : LCH-11/21/31/11-2C


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 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.
  • Power supply leakage breaker.
  • Over current protection.
  • Open door alarm.
