Temperature & Humidity Chambers
Wide temperature range down to -70 °C and high advanced safety features for quality and reliability
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℃.
