Altitude Chambers - Altitude, Humidity, Temperature Test Chambers - Vacuum Chambers

The RH-Series from Russells Technical Products

Altitude simulation testing is important for manufacturers of products that might be shipped via air. It is especially important for defense and aerospace applications where pressure and vacuum conditions are even more intense. Russells RH-Series altitude/temperature and altitude/temperature/humidity chambers offer performance flexibility and reliablility for today's mixed-environment testing requirement. Control the temperature environment for testing your product while simulating various altitude environments from site level to 100,000 feet.  The same chamber can be utilized for humidity testing to 95% relative humidity.  We offer an optional extended range to simulate sea level testing when your site is significantly above sea level.

Russells RH-Series chambers can provide the following combinations of controlled testing environments:

• Altitude
• Temperature
• Temperature and Altitude
• Temperature and Humidity
  

Russells RH-Series chambers are available in sizes from 8 cu ft (225 L) to walk-in size. A Russells application engineer can assist you in selecting the altitude chamber configuration and size that's best for you or we can custom design any standard test chamber configurations.
