 Testing chambers suited to a variety of
environmental simulations are used by NU Labs to conduct
nearly every climatic test for commercial and military
specifications. Of the many test chambers available at the lab, the largest provides 1400 cubic feet of work space and temperature variations from extreme heat to arctic cold. With a 10’x10’x14’ temperature humidity chamber, large test articles, like these Laser Guided Training Rounds (LGTR) recently tested for Lockheed Martin Tactical Defense Systems are no problem.

Several chambers are capable of rapid temperature transitions of up to 22°C/min. Other chambers combine temperature variation with nearly all levels of humidity, temperature, or atmospheric conditions with altitude of up to 100,000 feet. Vibration can also be induced in at least half of the lab's testing chambers for true combined temperature/humidity/vibration environment testing. All of our chambers can also be equipped to simulate solar effects.

For testing the effect of salt water corrosion on marine equipment, the lab contains a salt spray chamber in which accelerated simulations can be produced at varying temperature and salinity levels. We also provide complete enclosure testing that tests for spraytight, watertight, dripproof, immersion, and wind and rain conditions.
