BROCHURE URL COPY Inquiry Form

Control range

Temperature range from -70 to 150°C Humidity range from 25 to 95% RH

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.
