LIB Environmental Simulation Industry was founded in 2009 and has more than 16 years of professional experience in the design, development, and manufacturing of environmental test chambers. We focus only on environmental simulation equipment, which means all our engineering expertise and production processes are dedicated to this single field. This specialization allows LIB to deliver stable performance, advanced technology, and highly reliable testing solutions.
LIB provides a full range of environmental testing chambers used to simulate real-world natural and extreme conditions. For temperature and humidity environmental simulation, we provide temperature and humidity test chambers, fast temperature change chambers, and thermal shock chambers (2-zone and 3-zone), designed to simulate extreme hot, cold, and humidity conditions for product reliability testing.
For salt corrosion testing, we offer salt spray corrosion test chambers, cyclic salt corrosion chambers, and SO₂ cyclic salt corrosion chambers to simulate long-term exposure to salt mist, industrial pollution, and harsh chemical environments.
For rain, dust, and outdoor protection testing, we provide waterproof test equipment covering IPX1 to IPX9K standards and MIL-STD-810 blowing rain tests, as well as sand and dust test chambers including IP5X/6X and MIL-STD-810 models.
For aging and material life testing, we supply xenon arc aging chambers, UV weathering test chambers, ozone test chambers, and SO₂ & mixed gas corrosion systems to simulate sunlight, ultraviolet exposure, and toxic gas environments. For large-scale or special applications, LIB also provides walk-in environmental chambers and fully customized solutions designed according to customer requirements.
Quality assurance is strictly managed under ISO 9001 quality management system, and all products comply with international standards including IEC, ISO, ASTM, MIL-STD, and other industry-specific regulations. Before shipment, every test chamber must pass multiple inspection stages, including incoming material inspection, in-process quality control, and a continuous operation test. This ensures stable performance, long service life, and high accuracy even under continuous industrial use.
LIB also provides strong global service support. With 29 agents and 6 service centers, we ensure fast technical response and local service coverage. Customers can access 24/7 English technical support via email, phone, and video call. We also provide regular global on-site inspections and maintenance services to ensure stable equipment performance and early detection of potential issues. Each product includes a 3-year warranty.
With strong engineering capability, strict quality control, global service network, and fast delivery ability, LIB has become a trusted long-term partner in the global environmental testing industry.
