Precision Testing with Temperature, Humidity, and Altitude Chambers
Discover the power of our temperature, humidity, and altitude chambers, designed for accurate and reliable environmental simulations. Perfect for testing product durability, these chambers ensure your products meet the toughest industry standards.
Altitude Chambers combine temperature and altitude with optional humidity to test basic components or sub-assemblies for a variety of industries. Standard altitude chambers simulate altitude up to 100,000 feet (8.2 Torr) and higher levels optional up to 175,000 feet (.37 Torr). Optional extended ranges are also available to simulate sea level testing when your site is significantly above sea level.
These chambers meet many test standards for altitude testing including IEC and Mil-Stds.
