The humidity testing chamber simulates a wide range of environmental conditions for reliability and durability testing. Depending on the model, the temperature range extends from -70°C to +150°C, while humidity can be controlled from 10% RH to 98% RH. Various chamber volumes, temperature change rates, and customized configurations are available to meet specific testing requirements.
For product development, quality assurance, and compliance testing, a humidity testing chamber provides precise control of temperature and humidity conditions to reproduce real-world environmental stresses. It is widely used to evaluate condensation resistance, material stability, corrosion behavior, and long-term product reliability across industries such as electronics, automotive, aerospace, pharmaceuticals, and research laboratories.
Temperature range, humidity range, chamber volume, temperature ramp rate, and special testing requirements are important factors when selecting a system. Tell us your testing requirements, and the LIB industry team will help you configure the most suitable humidity testing chamber solution.

Anti-Condensation Design
You'll never stress approximately condensation trickling on your test tests. Our inventive slanted ceiling plan channels any dampness absent from the test zone, whereas multi-layer warm separator avoids temperature differentials that cause condensation. The dynamic condensate seepage structure guarantees nonstop operation without interruption.
High-Precision Steam Humidification System
Unlike conventional heating-tube humidifiers that make unsteady dampness bursts, our modern steam humidification with PID + SSR persistent control conveys smooth stickiness bends. The electromagnetic valve gives micro-level control, ensuring:
· Stable long-term operation without fluctuation
· Superior high-temperature, high-humidity stability
· Rapid low-humidity recovery speed
· Continuous humidity adjustment without overshoot
When you're testing car gadgets, PCBs, connectors, EV batteries, or semiconductor components, the 85°C/85% RH test standard requests unflinching execution. Our environmental chamber humidity control system is particularly designed for:
· 1000-hour continuous operation capability
· Stable humidity recovery after door openings
· Zero condensation dripping on test samples
· Intelligent compressor protection logic for extended lifespan
Your test results are only valid if conditions are consistent throughout the chamber. Our multi-airflow circulation design ensures uniform humidity distribution across all test positions, eliminating hot spots and moisture gradients that compromise data integrity.
Standard run of 20% to 98% RH covers most testing conventions, whereas our extraordinary low-humidity alternative expands down to 10% RH for specialized applications. This wide stickiness envelope implies one chamber handles assorted testing requirements.
Automatic Water Filtration System
Mineral buildup devastates warming components and makes upkeep migraines. Our integrated water filtration framework with programmed water renewal and level assurance keeps your temperature stickiness control chamber running easily for years.
Water-Electrical Separation Design
Safety and unwavering quality are foremost. Our autonomous water pipeline format keeps up total division between water circuits and electrical frameworks, with spill anticipation structures that ensure your venture and test samples.
Since 2009, we've adhered to ISO 9001 standards and earned CE certification verified by SGS and TUV. Our chambers deliver the stable performance international standards demand, backed by partnerships with Apple, IBM, Amazon, Intel, Mercedes-Benz, and BYD.
Every humidity testing chamber includes a 3-year warranty and lifetime service. Our 24/7 global support network spans 29 countries, with service centers strategically located in Malaysia, Canada, the United Kingdom, and the United States. If we can't repair your equipment within the warranty period, we'll replace it with a brand-new unit—no questions asked.
Your testing requirements are unique. Our engineering team excels at non-standard design and custom R&D, tailoring chamber dimensions, control systems, and special features to match your specific protocols and space constraints.
