Altitude Chambers are capable of simulating altitudes up to 200,000 feet, depending upon configuration. The overall temperature range is -70ºC to +177ºC. Humidity capabilities range from 20% to 98% RH, and workspace sizes range from 5 to 64 cubic feet. Altitude chambers provide exacting performance and a high degree of reliability for your altitude testing needs. They have continuously welded, stainless steel and vapor-tight interior liners. They also have the linear pressure transducer to measure altitude and vertical-down recirculating conditioning stream.
