Altitude Test Chambers
Altitude testing is essential for military, industrial, aviation, and consumer applications where products or components experience low-pressure environments or must withstand rapid decompression combined with climate control. Russells RH (reach-in) and WH (walk-in) Series altitude chambers offer the performance, flexibility, and reliability required for today’s mixed environmental testing standards. An RTP altitude test chamber controls the temperature environment for product testing while simulating various altitudes, or can be used for stand-alone temperature and humidity testing. Russells can manufacture your altitude test chamber to meet MIL-STD, RTCA DO-160, and other test specifications.
What is an Altitude Test Chamber?
Our altitude test chambers control the temperature and/or humidity environment for testing your product while simulating various altitude conditions from site level to 200,000 feet. Some test standards require combined testing, therefore we offer a wide range of conditions including temperature, altitude, humidity, and vibration. Our altitude test chambers can meet RTCA DO-160 and MIL-STD-810H test specifications for icing and rapid decompression for avionics cabin pressure testing. Our rapid decompression option simulates sudden altitude change from 8,000 ft. to 60,000 ft. in 15 seconds.
