Temperature testing at altitudes up to 100,000 feet.

ESPEC provides custom-built altitude test chambers for simultaneous testing of temperature and low-pressure altitude conditions. Two common applications are:

  • Testing of avionics or other aerospace equipment to simulate actual conditions it might experience.
  • Simulation of high-altitude conditions similar to those found in mountainous regions.

Applicable test methods (depending on chamber system)

  • Mil-Std 202G (conditions 105C, A/B/C/F)
  • Mil-Std 810G (condition 500.5)
  • IEC 60068-2-39
  • IEC 60068-2-40
  • RTCA/DO-160F
  • JIS W 0812

Please let us know your anticipated test load & specification/method, and we can provide you with a tailored system for your requirements.


  • Temperature range from -70 to 170°C
  • Altitude range from ground to 100,000 feet
  • Optional humidity control when altitude system is off
  • Chamber interior size specified by customer
  • Automatic altitude control, integrated with temperature controller – No manual setting of altitude level!
  • Vacuum pump sized for climb/dive rate required by application
