The TestEQ EQT-series altitude test chamber reproduces controlled high-altitude environmental conditions for product development, qualification, reliability testing and research. Instead of testing at an actual high-altitude location, the chamber reduces atmospheric pressure to a defined condition in a controlled laboratory. The control parameter is absolute pressure; altitude is used as the equivalent environmental reference.

Applications

  • Aviation and aerospace equipment and instruments
  • Electronics and electromechanical components for high-altitude use
  • Automotive and EV components for altitude and pressure conditions
  • Materials, seals and packaging
  • Research and system-level test articles

Configuration and features

  • Wide altitude simulation range: 0 to 50,000 ft (0–15,000 m).
  • Precise pressure regulation: ±0.1 kPa.
  • Combined temperature and humidity control can be configured with pressure simulation.
  • Pressure control tolerance ≤ ±5 kPa across 40 kPa to 4 kPa, and ≤ ±0.1 kPa across 4 kPa to 1 kPa.
  • Fast depressurisation: 75.2 kPa to 18.8 kPa within ≤ 15 s (optional), and within ≤ 0.1 s (optional) for specific configurations.
  • Humidity range 10 % to 98 % RH; humidity deviation ≤ ±2.0 to 3.0 % RH (above 75 % RH) and ≤ ±5.0 % RH (≤ 75 % RH).
  • For large products, assemblies and system-level test articles, customised and walk-in altitude chambers can be developed around the required test volume, pressure range, temperature conditions and laboratory workflow.
  • Patent number CN202310792763.3.
