Capable of replicating extreme and cyclic conditions, the chamber supports temperature ranges from -20℃ to +150℃, -40℃ to +150℃, and -70℃ to +150℃, combined with a wide humidity range of 20% to 98% RH. Rapid heating and cooling rates up to 5℃/min ensure efficient thermal cycling for accelerated aging and stress tests.
This chamber enables precise simulation of real-world environments, including tropical humidity, desert heat, low-temperature plateaus, and rapid day-to-night temperature variations, to evaluate the endurance of materials, electronic components, automotive parts, aerospace assemblies, and complete systems. Its advanced control system allows programmable multi-segment temperature and humidity profiles, ensuring repeatable and accurate testing for long-term reliability studies.
Designed in compliance with international testing standards such as IEC, MIL-STD, ASTM, and JIS, the system meets the rigorous demands of environmental qualification, accelerated life testing, and product development verification. With interior volumes ranging from 100L to 1000L, it accommodates small-scale components as well as larger assemblies, providing laboratories and production facilities with a versatile and reliable solution for environmental stress testing.
Key Features of Temperature Humidity Cycling Chamber
Wide Temperature & Humidity Coverage
Supports ultra-low temperature testing down to -70℃ and high humidity conditions up to 98%RH, enabling comprehensive environmental adaptability evaluation.
Stable Heating and Cooling Capability
Equipped with a high-efficiency mechanical refrigeration system and advanced PID control algorithms, the chamber achieves reliable temperature ramping and tight control accuracy during long-duration cycling tests.
Multi-Segment Programmable Control
The color LCD touch screen controller allows users to program hundreds of temperature and humidity segments, supporting complex test profiles such as thermal shock cycling, damp heat aging, and combined temperature-humidity stress tests.

Product details
Temperature Humidity Cycling Chamber
Anti-Fog Viewing Window
The double-layer glass viewing window integrates an internal conductive heating film, effectively preventing condensation and fogging during high-humidity or rapid temperature change tests. This enables continuous real-time observation of specimen conditions without interrupting the test cycle.
Advanced Temperature & Humidity Controller
The PID-based touch screen controller provides intuitive operation, real-time trend monitoring, data storage, and remote communication. Test data can be accessed via PC or LAN, improving laboratory efficiency and traceability.
Sealed Cable Test Port
A silicone-sealed cable hole allows safe routing of power or signal cables while maintaining airtightness. This supports live component testing, voltage monitoring, current acquisition, and functional performance evaluation under environmental stress.
Efficiency Leap: Precision and Stability
The Temperature Humidity Cycling Chamber maintains stable control across the full humidity range of 20%RH to 98%RH, ensuring repeatable test results even during long-duration damp heat or cyclic humidity tests. Optimized airflow circulation guarantees uniform temperature and humidity distribution throughout the workroom, reducing spatial deviation and improving test consistency.
