*Humidity performance is subject to temperature and dew-point limits. Custom configurations available.
Advanced High-Altitude Environmental Testing
The NPD Altitude Test Chamber is designed to reproduce reduced atmospheric pressure from site level up to 100,000 ft (30.48 km), with extended altitude ranges available upon request. Combined temperature and humidity testing capabilities support realistic environmental simulation for critical equipment and materials.
The chamber supports low-pressure storage, operational performance, rapid decompression and combined temperature-altitude test profiles. Designed to support testing protocols including MIL-STD-810G/H Method 500.6, RTCA DO-160, IEC and IS standards, it provides a flexible solution for aerospace, defence, electronics, automotive and energy-storage industries.
Its programmable control system, precision-engineered pressure chamber and robust stainless-steel construction make it suitable for environmental qualification, reliability testing and research applications.

Remote Monitoring
PLC-based digital control supports remote monitoring and scheduled tests.
How the Altitude Test Chamber Works
Controlled simulation of pressure, temperature and environmental conditions.
Sample Preparation
Test samples are placed inside the chamber, and the required testing conditions are configured.
Pressure Simulation
The vacuum system reduces chamber pressure to simulate the required high-altitude conditions.
Environmental Control
Programmable profiles control applicable temperature, humidity and altitude conditions.
Monitoring & Evaluation
Operators monitor test conditions and component performance using the digital control interface.
Advanced Control System
The NPD Altitude Test Chamber features an advanced PLC-based digital control system with a user-friendly touchscreen interface. Operators can programme altitude, temperature, humidity and combined environmental testing profiles while accessing remote monitoring and test-scheduling functionality.
Temperature control can be combined with altitude testing up to 65,000 ft (20,000 m). Temperature and humidity control is available at site-level pressure. Combined temperature, altitude and vibration testing can also be configured for specialised qualification programmes.
Durable Pressure-Chamber Construction
The inner chamber is fabricated from brushed SS 304 stainless steel, heliarc welded and dye-checked for pressure integrity. A welded steel frame with removable access panels supports service accessibility, while fibreglass insulation contributes to stable pressure and temperature performance.
For battery and energy-storage testing, optional safety provisions can be configured according to EUCAR hazard-safety levels. These options are intended to support testing involving lithium-ion cells, battery packs and abnormal battery behaviours.
Applications & Industries
Suitable for environmental qualification and R&D testing.
