In March 2023, an American company, as a leading developer and supplier of diagnostic equipment in the ophthalmology industry, purchased 5 units of our LIB test chambers, including temperature and humidity test chambers, water srpay test chambers, xenon test chambers and salt spray test chambers, expanding their laboratory equipment.
The test chambers operate well and plays a very important role in the development of new products and precision instrument testing.
On March 25, 2024, we came to the customer's laboratory and saw the operation and usage of the test chamber on site. Everything was running well and the customer was very satisfied.

The LIB team gave suggestions and plans for test chamber maintenance. At the same time, we look forward to providing more equipment to expand the laboratory to test the reliability of products for customers.
The LIB constant temperature and humidity test chamber is designed for laboratories that require precise environmental control and reliable long-term operation under demanding test conditions. It offers a wide temperature range from –86 °C to +150 °C and humidity control between 20% and 98% RH, enabling a broad range of applications such as low-temperature storage, thermal cycling, high-temperature damp heat exposure, and stability verification testing. The system maintains temperature stability within ±0.5 °C, overall uniformity within ±2 °C, and humidity precision of ±2.5% RH, delivering consistent and reproducible results for both compliance testing and internal quality validation.
Featuring high-precision PT100 Class A temperature sensors with a sensing resolution of 0.001 °C, the chamber delivers continuous and accurate environmental monitoring to the PID intelligent control system for precise adjustment. Its optimized multidirectional air circulation structure promotes consistent airflow inside the test area, reducing temperature and humidity variation while maintaining chamber uniformity within ±1.5 °C. The system also offers efficient thermal response performance, supporting heating speeds up to 3 °C/min and cooling speeds of 1 °C/min to shorten test cycles without compromising stability.
The programmable controller is capable of storing up to 120 customizable test programs, with each program supporting up to 100 individual steps. This enables users to perform sophisticated environmental simulations, long-term durability verification, ESS testing, and continuous damp heat aging tests lasting up to 1000 hours. Constructed with a SUS304 stainless steel inner chamber for enhanced corrosion resistance, the equipment is further equipped with comprehensive safety protection functions to ensure reliable operation, long service life, and stable performance under continuous laboratory use.

The IPX1/IPX2 drip system delivers a calibrated 1 mm/min drip rate with specimen rotation at 1 rpm, while IPX2 includes a 15° tilt function for four-direction testing. For IPX3/IPX4, the stainless steel oscillating tube provides ±60° to ±180° swing angles with φ0.4 mm evenly spaced spray holes to simulate rainfall and splashing conditions. IPX5 and IPX6 utilize dedicated nozzles with 6.3 mm and 12.5 mm diameters, delivering 12.5 ± 0.625 L/min and 100 ± 5 L/min flow rates respectively, at controlled pressures and spray distances of 2.5–3 m.
A closed-loop water circulation and filtration system significantly reduces water consumption and allows unattended operation. The adjustable turntable supports loads up to 50 kg and accommodates irregular or large samples. Built-in viewing windows, LED lighting, and optional power supply connections enable real-time functional testing of electronic devices during spray exposure. The full SUS304 stainless steel construction ensures corrosion resistance and durability under continuous wet conditions.
The LIB xenon weathering test chamber accurately reproduces natural sunlight and climate cycles to accelerate material aging in a controlled laboratory environment. Equipped with a 4500 W or 6500 W water-cooled xenon arc lamp, it covers the full spectral range of 280–800 nm, closely simulating outdoor daylight, window-filtered light, and enhanced UV exposure through interchangeable optical filters.
The equipment is engineered in compliance with widely recognized international weathering test standards such as ASTM G155, ASTM D6695, and ISO 11341, making it suitable for standardized accelerated aging and durability evaluation. Users can create customized multi-step testing sequences that combine xenon light exposure, moisture condensation or water spray, humidity regulation, and dark-cycle recovery stages to reproduce complex outdoor climate conditions with high accuracy. The irradiance control system supports precise wavelength regulation at 340 nm or 420 nm, ensuring stable light intensity and reliable repeatability between different test laboratories.
Throughout the testing process, the equipment maintains black panel temperature stability within ±2 °C and humidity accuracy within ±5% RH, allowing dependable simulation of both high-temperature dry environments and humid aging conditions. Its rotating sample holder is capable of accommodating up to 42 specimens simultaneously, helping each sample receive consistent and uniform exposure while reducing discrepancies caused by placement position.
An intelligent PID monitoring system continuously controls and records critical parameters including irradiance, chamber temperature, and humidity. Test records can be saved and exported through USB or Ethernet connectivity, supporting quality tracking, report generation, and laboratory documentation management. Additionally, the integrated closed-loop water circulation design minimizes water usage during spray and condensation operations, improving resource efficiency and supporting environmentally conscious operation.
By combining precise environmental control, programmable testing flexibility, and reliable long-term performance, the chamber provides a complete accelerated weathering solution for industries requiring rigorous material durability verification, product performance testing, and international standards compliance.
