Temperature & Humidity Chambers
Specially designed for conducting each different experiment at once.
Environmental test equipment with dual chambers.
with optional recorder
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 system reduce water consumption 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.
Convenience
-
Three different volume sizes are available to suit any users’ needs.
-
Corrosion resistance stainless steel chamber and electric polished humidification tank.
-
Water supply during operation is also available for long term test purposes.
-
Direct water system provides user great convenience when performing long-term tests. (optional)

- Display indicates abnormal temperature changes or power failures.
- Selective bilingual language support.
(Korean / English or English / Chinese, selectable only when placing an order)
- Temperature and other operating parameters can be recorded using a six channel digital recorder.(optional)
-
Computer interface.
- RS-485 communication port (optional) enables connection up to maximum 32 units. Simultaneous monitoring and operating of multiple units is an available feature.
- Program patterns are simple to set with the use of our software.
- Easy to check status of real-time operations. Graph data supports easy understanding.
- Storage and documentation of programs.
- Data with saving capabilities in excel and text format.
- Storage of program information, backup of value settings, recovery, and temperature values.
- RS-232 communication port as standard offer.
