Temperature and Humidity Chamber
IEC 60068-2-38 Temperature and Humidity Chamber
Temperature and Humidity Chamber (also known as Constant Temperature and Humidity Chamber or Damp Heat Test Chamber) is a core testing device that precisely simulates constant or alternating temperature and humidity environments within a sealed space through heating, cooling, humidifying, and dehumidifying systems. It is used for product environmental adaptability, reliability, aging, and quality validation.
Temperature & Humidity Test Chamber
1.Overview of Temperature & Humidity Test Chamber
Also known as constant temperature & humidity chamber or damp heat test chamber, it accurately simulates constant or alternating temperature and humidity environments in a sealed space through heating, cooling, and humidification systems. It is a core testing instrument for verifying product environmental adaptability, reliability, aging resistance, and quality.
2. Main Types of Temperature & Humidity Test Chambers
- Standard Constant Temperature & Humidity Chamber: Maintains fixed temperature and humidity for general stability testing.
- High-Low Temperature Alternating Damp Heat Chamber: Supports programmable temperature & humidity cycling to simulate day/night or seasonal changes.
- Rapid Temperature Change Chamber: Fast temperature ramp rate (5–20℃/min) for simulating sudden environmental changes.
- Explosion-Proof Temperature & Humidity Chamber: Explosion-proof design for flammable and explosive samples such as batteries and chemical products.
- Walk-in / Drive-in Chamber: Large-volume chamber for full testing of complete vehicles and large equipment.
3. Standards
- IEC 60068-3-6: Performance confirmation for temperature and humidity chambers.
- IEC 60068-2-78: Constant damp heat (Cab).
- MIL-STD-810: U.S. military standard environmental test.
4. Applications
- Environmental Adaptability Testing: Simulate high/low temperature, high/low humidity, and temperature-humidity cycling.
- Reliability & Accelerated Aging: Dual 85 test (85℃ / 85% RH), long-term damp heat aging.
- Performance Verification: Stability of electrical, mechanical, optical, and material properties under temperature and humidity.
- Quality & Compliance: Meet national, military, IEC, CE, GMP certification requirements.
- R&D & Screening: Early defect detection, design and material optimization.
