How can a benchtop temperature and humidity chamber accelerate material aging

In material development, time is always the biggest constraint. Polymers, electronic components, batteries, coatings, and composite materials may take years to show real-world degradation under normal conditions. Waiting for natural aging is costly, slow, and often impractical in competitive R&D and quality control environments.

This challenge is echoed by real users in the field. "Thanks again for the advice. Now I am confident and understand how to use the climate chamber, especially the FIX mode, which is quite easy to use," says Srichon Nithichareon, Battery Shop Executive. Practical operation, intuitive control, and fast learning curves make accelerated aging not only possible-but efficient and reliable in daily laboratory work.

LIB benchtop temperature and humidity chamber is designed exactly for this purpose. It delivers laboratory-grade environmental control in a compact, quiet, and highly precise format, allowing material aging studies to be conducted directly at the workbench while fully complying with international testing standards.

Accurate temperature control is the foundation of accelerated aging. LIB's benchtop chamber operates across a wide temperature range from –20 °C, –40 °C, or –70 °C up to +150 °C, depending on configuration. Heating rates reach 3 °C/min, while cooling rates reach 1 °C/min, allowing rapid thermal stress cycles that accelerate chemical reactions such as oxidation, hydrolysis, and polymer chain scission.

Stable humidity control drives moisture-related degradation. Humidity is programmable from 20 % to 98 % RH, with deviation controlled within ±2.5 % RH. High-humidity environments-such as 95 % RH at 40–70 °C-are critical for simulating damp heat, humidity freeze, and hydrolysis aging, as referenced in IEC 60068-2-30 and related standards.

High-precision sensors ensure data reliability. The chamber uses PT100 Class A temperature sensors with 0.001 °C resolution, continuously feeding data to a PID controller. This tight feedback loop keeps temperature fluctuation within ±0.5 °C and chamber deviation within ±2.0 °C, ensuring that every specimen experiences the same aging stress.

Uniform airflow prevents uneven aging. Low-noise centrifugal fans create top-down circulating airflow, eliminating hot or humid spots. Uniform conditions are essential when aging multiple samples simultaneously, especially for compliance testing and comparative studies.

Compact Design with Industrial Performance

With interior volumes of 50 L (TH-50) and 80 L (TH-80), and external dimensions as small as 820 × 1160 × 950 mm, the chamber fits beside a workbench or under a hood. Despite its size, it delivers the same environmental precision expected from full-size chambers.

Ultra-Quiet Operation

Operating at ≤65 dBA, the chamber is quieter than a typical office printer. This allows continuous aging tests in shared laboratories without disrupting measurements, discussions, or video meetings.

Fast Aging Cycles, Higher Throughput

Accelerated ramp rates shorten test duration. A thermal cycling test that would take days in passive environments can be completed in hours. With support for 120 programs, each containing 100 steps, complex aging profiles-such as temperature-humidity cycling followed by high-temperature soak-run automatically.

Reliable Cooling and Eco-Friendly Refrigerants

The mechanical compression refrigeration system uses TECUMSEH compressors. This ensures strong low-temperature performance down to –70 °C while meeting environmental requirements.

Durable Construction for Long-Term Aging Tests

The workroom is built from SUS304 stainless steel, resistant to corrosion under high humidity and temperature extremes. The exterior uses powder-coated A3 steel, ensuring structural stability over long test campaigns.

Data Connectivity and Remote Control

Ethernet, USB, and RS232 interfaces allow real-time monitoring, data logging, and CSV report export. One PC can manage multiple chambers, improving efficiency in aging test labs and production environments.

Q1. How is the temperature and humidity chamber calibrated?
Factory calibration includes multi-point temperature calibration using 9 evenly distributed probes and humidity calibration using the dry- and wet-bulb comparison method, ensuring uniformity and accuracy before delivery.

Q2. How often should the silicone sealing ring be replaced?
It is recommended to replace the silicone door sealing ring every 3 years to maintain airtightness and test accuracy.

Q3. Will custom cable holes or observation windows delay delivery?
Standard customization does not delay delivery. Special optical glass windows may add 5–10 days depending on design requirements.

Q4. What refrigerants are used for European markets? Can CO₂ be used?
LIB chambers use low-GWP refrigerants compliant with current EU regulations. CO₂ refrigerant cannot be directly substituted, as it requires a different system design.

Q5. How long does it take to reach the set humidity value?
In most cases, the chamber reaches the target humidity within 30 minutes, depending on temperature and load conditions.

A benchtop temperature and humidity chamber is no longer a compromise-it is a strategic tool for faster material validation. With precise environmental control, fast ramp rates, and compliance with global standards, LIB's benchtop temperature and humidity chamber helps laboratories shorten development cycles, uncover failure mechanisms early, and deliver reliable products to market with confidence.
