Performance
- Microprocessor PID control / Temperature calibration / Automatic tuning.
- Advanced performance of low and high temperature and humidity control, achieved by adapting the humidification tank exterior to the chamber, added benefit for long term test.
- Water recycling and filtering system reduce water consump-tion for longer operation
- Air-tight door closure with perfect sealed packing.
- Heat-resistant silicone packing completely blocks high heat leakage from the inner chamber.
- Two-point door latch also enhances tightness to door closure.
- Energy efficiency is achieved by optimization of the insulation system.
- Even if the unit is operating at max. temperature, the surface of the unit doesn’t allow high temperatures of over 60℃.
Safety
- Built in door lock with a key.
- Automatic shut off after overheat alarm.
- Low and empty water level alarm.
- Power supply leakage breaker.
- Over current protection.
- Open door alarm.
