Durable Temperature, Humidity & Altitude Chamber for Lab & Industrial Use
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. JQTA Series altitude chambers offer the performance, flexibility, and reliability required for today’s mixed environmental testing standards. An 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.
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.
Series chambers can provide the following combination of controlled testing environments:
» Altitude: Site level to 100,000 ft (30,500m)*
» Temperature: -70°C to +180°C (-100F to +356F)
» Temperature and altitude (temperature controllable to 65,000 ft or 20,000m)
» Temperature and humidity at site altitude:
10% to 95% RH within the bounds of a +85°C (+185o F)
max dry bulb and a +4°C (+40 F) min dewpoint*
» Temperature, altitude, and vibration
» RTCA DO-160 icing and various other combined environmental tests
» Rapid decompression
*extended ranges available JQTA Series chambers are available in all sizes from small reach-ins to custom drive-in projects. A application engineer will assist you in selecting the chamber configuration, size, and capabilities to meet your testing needs.
