LIB's Constant Climate Environmental Test Chamber is designed for laboratories that demand precision, reliability, and efficient use of space. Covering a wide environmental range from –86 °C to +150 °C with humidity control from 20 % to 98 % RH, it supports accelerated testing of electronics, materials, and pharmaceutical products. High-precision PT100 Class A sensors ensure temperature stability within ±0.5 °C and humidity control within ±2.5 % RH, while fast ramp rates of 3 °C/min for heating and 1 °C/min for cooling reduce test cycle times. Its compact, low-noise design allows placement directly beside workstations, making it ideal for R&D, quality assurance, and laboratory validation applications.
This Constant Climate Environmental Test Chamber complies with a broad range of international standards, including IEC 60068 (temperature and damp heat),JESD22 (semiconductor stress testing), ISO 16750 (automotive electronics), ASTM D4332 (packaging and material conditioning)and so on. Such compliance ensures confidence in testing across electronics, automotive, aerospace, and life sciences sectors.

The chamber supports programmable control with up to 120 test programs and 100 steps per program, enabling long-term cyclic testing and stable unattended operation.
Functional Advantages
1. Flexible Capacity and Workroom Design: Offered in capacities from 100 L to 1000 L, the chamber accommodates a wide range of sample sizes and testing requirements. Its spacious interior ensures easy placement of components, materials, or assemblies while maintaining uniform temperature and humidity throughout the workroom.
2. Broad Environmental Simulation Range: Temperature ranges from –40 °C to +150 °C (optional –86 °C) with humidity control from 20 % to 98 % RH, enabling simulation of extreme environmental conditions for reliability and durability testing.
3. High Accuracy and Uniformity: Optimized airflow generated by centrifugal fans, combined with perforated sample shelves, ensures uniform temperature and humidity distribution throughout the workroom. High-precision PT100 Class A temperature sensors deliver ±0.5 °C temperature stability, while wet-bulb humidity sensors maintain ±2 % RH accuracy, guaranteeing repeatable and reliable results for all samples during extended testing cycles.
4. Rapid Heating and Cooling Performance: Heating rates of up to 3 °C/min and cooling rates of 1 °C/min reduce test cycle time and support accelerated environmental testing.
5. Durable Construction and Comprehensive Safety: The interior is made of SUS304 stainless steel for corrosion resistance, while the reinforced A3 steel exterior ensures structural durability. Multiple safety protections—including over-temperature protection, leakage protection, and phase monitoring—ensure safe and reliable operation.
6. Customizable Cable Holes for Functional Testing: Equipped with sealed cable holes (standard φ50 mm, customizable in size, quantity, and position), the chamber allows powering and monitoring of samples during testing. This feature enables real-world operational simulations, including voltage monitoring, sensor operation, and remote data acquisition, without compromising temperature and humidity stability inside the workroom.
