Temp RH Chamber - Precision Climate Testing Solutions
At Xi'an LIB Environmental Simulation Industry, we know your products need to withstand real-world conditions — from scorching heat to freezing cold, from dry air to saturated humidity. With over 17 years of manufacturing expertise and a global service network, our chambers deliver the precise, repeatable results your testing protocol demands, whether you're testing electronics, pharmaceuticals, automotive components, or materials.
Precision You Can Rely On
Sophisticated refrigeration systems work seamlessly with intelligent heating elements to maintain stability within ±0.5°C and ±2% RH. With a broad operating range — 10% to 98% RH and -70°C to +150°C — a single chamber can replicate everything from tropical humidity to desert dryness, giving you full control over the exact conditions your products will face.
Temperature Range | Humidity Range | Typical Applications |

Cutting-Edge Climate Control Technology of Temp RH Chamber
Dual Refrigeration System
Cascade refrigeration ensures fast temperature changes and steady performance, even at extreme lows.
Intelligent Humidity Regulation
Automatic humidification/dehumidification keeps RH precisely on target without overshoot.
Auto Water Supply
Integrated water level monitoring eliminates manual refilling, ensuring uninterrupted operation during long test cycles.
Anti-Condensation Design
A triple-layer heated observation window keeps samples clearly visible, while high-density polyurethane foam insulation minimizes heat loss and prevents exterior condensation.
Energy-Efficient Operation
Intelligent refrigeration control activates cooling only when needed, cutting energy use by up to 30% versus conventional designs — with advanced insulation and efficient heat exchange further reducing waste during heating and cooling cycles.
