Its robust construction and advanced features ensure reliable, long-term operation for even the most demanding research and quality control needs.

Key Features and Benefits

Performance & Efficiency

• Precision Control: A microprocessor PID controller, along with temperature calibration and automatic tuning functions, ensures exceptional accuracy and stability.
• Advanced Humidification System: The humidification tank is located outside the main chamber, allowing for superior control of both low and high temperature and humidity levels, which is crucial for long-term testing.
• Water Conservation: A built-in water recycling and filtering system significantly reduces water consumption, enabling longer, uninterrupted test cycles.
• Superior Insulation: The chamber features an optimized insulation system and an air-tight door with heat-resistant silicone packing and a two-point latch. This design prevents heat leakage and improves energy efficiency, keeping the exterior surface temperature below 60°C even at maximum operating temperatures.

Safety & Reliability

• Comprehensive Safety Alarms: The system is equipped with multiple safety features, including alarms for overheating, low water levels, and open doors.
• Secure Operation: A built-in door lock provides physical security for your samples.
• Electrical Protection: The unit includes a power supply leakage breaker and over-current protection to safeguard both the chamber and your facility.

User Convenience & Accessibility

• User-Friendly LCD Controller: A 5.7-inch color touchscreen provides an intuitive interface for programming and monitoring. Users can view set and present values simultaneously, observe progress in graph mode, and access settings in English, Chinese, or Korean.
• Easy Water Management: A front-loading, portable water container simplifies refills. For continuous, long-term tests, an optional direct water system is available.
• Excellent Sample Visibility: A tempered glass door with an integrated heating wire prevents condensation, while energy-efficient LED lighting illuminates the interior. An optional inner glass door is also available for enhanced monitoring.
• Flexible Connectivity: A 50mm cable port comes standard for routing external probes and wires. Additional ports (50mm or 80mm) can be custom-ordered.
• Mobility: Casters are included for easy installation and relocation of the unit.

Advanced Programmability

• Extensive Programming: The controller supports up to 120 patterns with 100 segments each, allowing for complex test protocols.
• PC Interface: An RS-232 port is standard. The optional RS-485 port allows up to nine units to be connected and controlled simultaneously via our intuitive software, simplifying program setup, data storage, and backup.
