In August 2026, LIB Industry completed the installation and commissioning of a Constant Temperature and Humidity Test Chamber for a research laboratory at the University of Science and Technology of China (USTC). The purchase came through a referral: the professor's own mentor at USTC had previously used LIB's environmental testing equipment and, satisfied with its accuracy and reliability, recommended LIB when this laboratory began evaluating suppliers for a new chamber. This installation reflects the trust LIB has built with the academic research community and its growing reputation among Chinese universities for dependable environmental testing solutions.
【LIB Delivers High-Precision Environmental Testing for USTC Research】
For USTC's research team, data integrity is non-negotiable. LIB's Constant Temperature and Humidity Test Chamber is built to meet that
standard, using PT100 Class A temperature probes with 0.001°C resolution and wet-bulb humidity sensors accurate to ±2.5% RH. The chamber holds temperature stability within ±0.5°C and humidity consistency within ±2.5% RH across every test run. Multi-directional centrifugal fans circulate air from all angles, keeping internal variation under ±1.5°C, so small samples and larger assemblies inside the chamber experience the same conditions, removing the need for re-runs caused by uneven hot or cold spots.
The equipment is also built for demanding daily use in an active research setting. The interior is lined with SUS304 stainless steel for corrosion resistance and easy cleaning, while the A3 steel exterior with protective coating withstands routine bumps and spills. Silicone door seals prevent leaks, and a frost-resistant observation window paired with built-in LED lighting lets researchers check samples without opening the door
mid-test.
Sample racking inside the chamber was configured to the laboratory's specific research needs, and the unit supports up to 120 stored test protocols with 100 steps each, allowing the team to move between different test sequences, from material aging studies to thermal shock cycles, without reprogramming each time. Ramp rates of 3°C per minute for heating and 1°C per minute for cooling allow a -40°C to +85°C cycle to complete in under 45 minutes, cutting testing time significantly compared to standard chambers, while long-duration holds remain stable for damp-heat aging tests running for days or weeks without drift.
【LIB Supports USTC with Full Installation and Ongoing Technical Service】
The chamber arrived fully assembled with leveling castors and integrated power and water hookups, allowing the research team to begin running tests within hours of delivery. A color touchscreen interface with PID-based controls made it straightforward for the laboratory's researchers and graduate students to set up and save complex temperature and humidity cycles. LIB's technical team was on hand throughout installation and commissioning to walk the laboratory staff through operation and ensure the chamber met the research group's exact requirements from day one.
"Having a professor recommend us to their own former mentor's lab, and now to this next research group, means a great deal to us," said LIB's Director of Global Sales. "It tells us that the accuracy and reliability we build into every chamber are the things that matter most to the people using them, year after year."
