Enhanced LIB Temperature and Humidity Test Chamber with Vibration, CO₂, RF Shielding, and Full-Service Support

Environmental testing is no longer just a compliance step-it's a strategic advantage. As products become more complex, smaller, and globally distributed, they face diverse climates, mechanical stresses, and electromagnetic challenges. A reliable temperature and humidity test chamber is at the heart of proving durability, ensuring safety, and building customer trust.

LIB has developed an enhanced temperature and humidity test chamber that integrates advanced climate control with optional vibration, CO₂ management, and RF shielding. This single, modular platform supports industries ranging from automotive and aerospace to semiconductors, telecommunications, and biotech, providing precise, repeatable results that align with international standards.

When your products must survive harsh real-world conditions, precision environmental testing is not optional-it's mission-critical. From automotive control units to 5G modules and aerospace composites, you need consistent, traceable data to pass audits, satisfy customers, and accelerate time-to-market.

Global Standards Compliance
LIB chambers are built to meet or exceed leading test specifications worldwide, ensuring every data set is certification-ready:

IEC 60068: Environmental testing for electrical and electronic equipment

ISO 16750: Environmental requirements for road-vehicle electronics

IEC 61730: Photovoltaic module safety and weathering tests

ASTM D2247 / D1735: Moisture-resistance for coatings, plastics, and assemblies

ICH Q1A (R2), Q1B: Pharmaceutical stability protocols

ISO 11452 / ISO 7637: Automotive EMC and transient immunity

Test Precision & Repeatability

Wide Climate Envelope: –70 °C to +150 °C, 20–98 % RH

Tight Stability: ± 0.5 °C temperature fluctuation, ± 2.5 % RH humidity deviation

Rapid Cycling: 3 °C/min heating, 1 °C/min cooling (average, unloaded)

High-Accuracy Sensing: PT100 Class A sensors with ± 0.001 °C resolution; chilled-mirror humidity measurement for continuous feedback

Uniformity Guaranteed: Multi-directional centrifugal fans and precision airflow baffles maintain < 1.5 °C gradient across all points in the chamber volume.

Easy Access: Built-in cable holes (size and position can be customized) let you safely run power and signal cables into the chamber so you can plug in and test your product while it's inside, without breaking the temperature or humidity seal.

These parameters allow accelerated aging, cold-resistance, heat-soak, and combined stress tests to be run with confidence-whether comparing production batches or validating prototypes against regulatory thresholds.

Operational Efficiency for High-Throughput Labs

7-inch PID Color Touchscreen: Stores 120 programs × 100 steps; supports ramp-soak-recovery cycles, dwell holds, and auto preconditioning

Remote Connectivity: Ethernet and USB ports enable real-time monitoring, batch logging, and one-click export to CSV/PDF for LIMS or QA integration

Water-Saving Humidification: Closed-loop condensate recovery reduces refills by 70–80 % and extends humidifier life

Low Noise, Safe Proximity: ≤ 65 dB(A) during full operation, enabling use near workstations or in mixed R&D spaces

Multilingual UI: English, Chinese, and other language packs reduce interpretation errors for global teams

The LIB Temperature and Humidity Test Chamber Upgraded Design Incorporates Vibration, CO₂ Control, and RF Shielding

Real-world reliability often demands more than climate alone. Electronics must endure RF interference, materials must survive corrosive gases, and mechanical assemblies must pass shock and vibration profiles. LIB integrates these complexities into one modular platform:

Integrated Vibration Testing

Purpose: Combine thermal cycling with mechanical shock to uncover latent failures early

Capability: IEC 60068-2-6 (sinusoidal vibration) and IEC 60068-2-27 (shock) profiles

Result: A single workflow that evaluates solder joint fatigue, connector stability, and structural integrity under simultaneous thermal and mechanical load

CO₂ Climatic Control

Range: 0–20 % CO₂ concentration, ± 0.4 % accuracy via infrared sensors and precision valves

Use Cases:

Corrosion Studies (ISO 187, ASTM D2247): Simulate greenhouse or industrial emissions on coatings, metals, and polymers

Agricultural & Biological Testing: Controlled CO₂ for seed germination, tissue culture, or microbial studies under defined TH profiles

Electronics Reliability: Evaluate circuit corrosion, solder degradation, and battery gassing in high-CO₂ atmospheres

RF Radio Frequency Shielded Temperature Chamber

Precise Temperature Control - Temperature cycling from –20 ℃ to +85 ℃ ensures stable thermal conditions for sensitive tests.

Advanced RF Shielding - Green RF shielding box effectively blocks external electromagnetic interference.

High Shielding Performance - 60–90 dB attenuation (30 MHz–6 GHz) delivers reliable, interference-free wireless testing.

Wide Application Coverage - Ideal for 5G, Wi-Fi, Bluetooth, IoT, wearables, and automotive/aerospace ECUs.

Flexible Configuration - Optional vibration and CO₂ control can be added or combined to meet specific reliability goals.

Safety & Serviceability - Maintains LIB's proven uniformity, safety interlocks, and easy maintenance.

All three enhancements-vibration, CO₂, and RF shielding-can be combined or implemented individually, allowing you to build a chamber tailored to your exact reliability goals while maintaining LIB's hallmark uniformity, safety interlocks, and serviceability.

Even the best chambers require consistent care to protect data integrity, avoid downtime, and extend operational life. LIB's global service ecosystem is designed around predictability, transparency, and speed:
