LIB portable cold heat controlled temperature humidity test chamber features a compact benchtop structure with internal capacities ranging from 50 L to 80 L, making it suitable for small samples, PCBs, sensors, and modules. Operating noise is controlled at ≤65 dBA, allowing continuous testing in shared laboratories without disrupting daily work. The chamber supports programmable control with up to 120 test programs and 100 steps per program, enabling long-term cyclic tests and unattended operation. With uniform airflow design and a corrosion-resistant stainless steel interior, it delivers consistent test conditions and reliable performance for daily R&D and quality verification tasks.
Technical Advantages
1. Exceptionally Low Noise Performance: the benchtop environmental temperature chamber operates at noise levels of ≤65 dBA, making it noticeably quieter than most office equipment. Even during continuous temperature and humidity cycling, the chamber runs smoothly without generating distracting sound. A silent mode is also available as an optional feature, further reducing noise for shared laboratories, cleanrooms, and R&D spaces where concentration, precise measurements, and uninterrupted communication are essential.
2. Compact Benchtop Footprint: designed with laboratory space efficiency in mind, the TH50 benchtop environmental test chamber features overall dimensions of 820 × 1160 × 950 mm, allowing it to be positioned directly next to workstations or beneath laboratory hoods. Its small physical footprint helps laboratories conserve valuable floor space while still providing full environmental testing functionality typically associated with larger chambers.
3. Broad Temperature and Humidity Simulation Capability: this compact environmental test chamber supports an extensive operating range from –86 °C to +150 °C with humidity control between 10 % and 98 % RH. A powerful refrigeration system paired with responsive electric heating enables accurate simulation of extreme cold, high heat, and high-moisture environments. The chamber is suitable for testing electronics, materials, batteries, and components under realistic environmental stress conditions.
4. High Accuracy and Environmental Uniformity: using PT100 Class A temperature sensors with a resolution of 0.001 °C, the chamber delivers precise and stable environmental control. Intelligent PID regulation maintains temperature stability within ±0.5 °C and humidity within ±2 % RH. Optimized airflow generated by centrifugal fans minimizes spatial variation, ensuring all samples are exposed to consistent test conditions for reliable and repeatable results.
5. Fast Heating and Cooling Performance: with heating rates up to 3 °C per minute and cooling rates of 1 °C per minute, the chamber significantly shortens test cycle times. Programmable control allows multiple test stages to be combined into a single automated sequence, reducing manual intervention and improving laboratory productivity. This capability supports accelerated testing and faster data turnaround.
6. Robust Construction and Integrated Protection: the test chamber interior is manufactured from SUS304 stainless steel, offering excellent resistance to corrosion in high-humidity environments. A reinforced 4 mm A3 steel outer structure with protective coating ensures long-term mechanical durability. Comprehensive safety features—including over-temperature protection, leakage current monitoring, grounding protection, and phase detection—provide reliable operation and safeguard both personnel and test samples.

Typical Tests
The Portable Cold Heat Controlled Temperature Humidity Test Chamber can perform a wide range of environmental tests to evaluate sample reliability under different conditions. Thermal shock cycling tests rapidly alternate between -40°C and 85°C to assess structural and functional stability. Thermal cycling tests vary temperature between 0°C and 70°C to evaluate performance under repeated fluctuations. High- and low-temperature tests expose samples to extremes of 85°C and -20°C to simulate harsh environments. Humidity and damp heat tests operate at up to 85% RH to assess moisture resistance, while shelf life and storage tests evaluate stability at 25°C and moderate humidity over extended periods. Humidity freeze tests cycle samples between -20°C and 25°C to check durability under alternating cold and humid conditions. Finally, hydrolysis aging tests expose samples to temperatures from 20°C to 70°C with high humidity to study material degradation over time. All test conditions are continuously monitored to ensure accurate, reliable, and repeatable results.

FAQs on the Portable Temperature and Humidity Test Chamber
FAQ 1: For fast temperature change rates, what is the maximum the chamber can achieve? Can it reach 20°C/min?
A1:The standard ramp rate of the Portable Temperature Humidity Test Chamber is 5–10°C per minute. However, we can customize the chamber to achieve 20°C/min or even higher, fully supporting non-standard configurations to meet your specific application requirements.
FAQ 2: Does the Temperature Humidity Test Chamber have audible and visual alarms?
A2: The chamber comes standard with an audible alarm to promptly notify of any critical abnormalities. If a visual alarm is needed, we offer it as an optional feature and can configure it flexibly according to your requirements.
FAQ 3: If a custom test port and viewing window are required, will there be delivery delays? What is the fastest delivery time?
A3: For standard test ports or common viewing window adjustments, the production schedule remains the same as regular units with no delays. For fully custom designs or non-standard specifications, production will be arranged to meet your requirements and ensure timely delivery. Installing optical glass viewing windows typically adds 5–10 days to the schedule, and we closely monitor the process to minimize wait time and get your equipment operational as soon as possible.
