Advantages
1. Advanced Operational Efficiency: The thermal shock chamber features a PID touchscreen controller supporting up to 120 programs with 100 steps each, allowing flexible and complex test profiles. Ethernet and USB connectivity enable real-time monitoring, data logging, and one-click report export, streamlining test management. Despite its capabilities, it operates quietly below 65 dB(A), making it ideal for laboratories, cleanrooms, and noise-sensitive environments.
2. Durability and Safety: Built for long-term reliability, the chamber interior uses corrosion-resistant SUS304 stainless steel, maintaining strength under high humidity. The exterior 4 mm A3 steel frame with powder coating provides industrial-grade durability. Safety systems—including leakage current protection, grounding, phase monitoring, and over-temperature shutdown—ensure operator and equipment safety during demanding tests.
3. Rock-Solid Precision: Equipped with high-accuracy PT100 Class A sensors delivering 0.001 °C resolution, the chamber ensures stable and consistent conditions. Advanced PID algorithms maintain temperature within ±0.5 °C and humidity within ±2.5 % RH, providing uniform exposure for all samples and guaranteeing repeatable, reliable results.
4. Fast and Flexible Cycling: Accelerate testing with rapid ramp rates—heating at 3 °C/min and cooling at 1 °C/min, with optional customization up to 20 °C/min. Preloaded programs support hundreds of sequential steps in a single profile, reducing setup time, increasing throughput, and enabling laboratories to quickly gather critical test data.
5. Quiet, Clean, and Efficient Design: The chamber operates at low noise levels below 65 dB(A), minimizing disruption in sensitive environments. Its design ensures stable internal conditions and easy maintenance, with features like corrosion-resistant interiors and efficient defrosting systems, extending equipment life while maintaining a clean and controlled test environment.

Product Operate Guide
Before starting, turn on the main power and verify that all connections are secure. Set the desired temperature, humidity, and ramp rates on the touchscreen controller according to your testing requirements. Load samples evenly on the shelves, avoiding contact with chamber walls or sensors to ensure uniform exposure. During the test, continuously monitor temperature and humidity, making sure they remain within the programmed limits. After completing each cycle, carefully remove the samples and clean the chamber interior, ensuring no spills or debris remain. Regular maintenance, proper handling, and adherence to safety precautions not only improve testing accuracy but also extend the equipment’s lifespan and protect operators from potential hazards.

Customizable Environmental Testing
Customize the temperature and humidity chamber to your specific testing requirements with a variety of optional configurations. Choose double doors for convenient access and efficient workflow, integrate airflow control for precise and uniform environmental conditions, or add a spray system to simulate moisture exposure. Advanced condensation prevention ensures accurate results even in high-humidity cycles, while increased chamber height and width accommodate larger or more numerous samples. Additionally, you can specify the size, shape, and quantity of cable holes and the number of sample shelves to perfectly match your test setup. These flexible options allow laboratories to optimize efficiency, expand testing capabilities, and achieve reliable, repeatable results under any temperature and humidity conditions.
