Advantages of the Walk-in Test Chamber
1. Large-Scale Testing Capacity: Designed for demanding industrial applications, LIB walk-in chambers offer spacious test areas from 3 m³ to over 100 m³. The large chamber volume allows testing of oversized products, multiple specimens, or full rack assemblies at the same time, improving testing efficiency and reducing the time required for validation programs.
2. Precise Temperature and Humidity Control: The chamber integrates high-accuracy PT-100 Class A sensors with advanced PID regulation technology to achieve stable environmental control. Temperature uniformity and humidity consistency are maintained throughout the workspace, with temperature accuracy up to ±0.5 °C and humidity control within ±2.5 % RH, ensuring reliable and repeatable test results.
3. Multi-Condition Environmental Simulation: Beyond standard temperature and humidity testing, the chamber can be configured to simulate various environmental stresses, including temperature extremes from –70 °C to +150 °C, humidity conditions from 20 % to 98 % RH, as well as combined factors such as salt spray, solar radiation, dust, rain, and vibration. It is widely used for durability and reliability verification in automotive, aerospace, electronics, and material research applications.
4. Optimized Energy Efficiency: The system adopts advanced insulation materials, efficient humidification technology, and intelligent energy management strategies to reduce operating power and water consumption. Automatic water-level monitoring and refill reminders support continuous operation while minimizing maintenance requirements and operating expenses.
5. Convenient Operation and Reliable Protection: A smart touchscreen controller provides simple programming, real-time status monitoring, and test data management. Ethernet and USB communication interfaces enable convenient connection with laboratory management systems. Multiple safety functions, including temperature protection, pressure monitoring, and water shortage alarms, together with a durable SUS304 stainless steel interior, ensure safe and stable operation over long service periods.

Walk-in Test Chamber Operating Guide
Before operation, ensure the chamber is properly leveled and connected to power and water. Place samples securely on the racks. Set test parameters via the touchscreen controller, including temperature (–70 °C to +150 °C), humidity (20%–98% RH), and test duration. Once started, the system automatically controls heating, cooling, and airflow to maintain stable conditions. PT-100 sensors and PID control ensure precise monitoring, with real-time data recording available and exportable via USB or Ethernet. After testing, remove samples safely and perform basic cleaning and maintenance to ensure reliable long-term operation.
