As their name implies, these chambers simulate Altitude, and almost always include Temperature control as well. If you need to simulate environmental conditions experienced by flight hardware as a plane quickly transitions from a hot tarmac in summer to a low-temperature, low-pressure 40,000 ft. altitude cruise condition, then this chamber is for you! Similarly, rocket and missile hardware can be tested up to 200,000 ft in this type of chamber from Russells Technical Products.

Equipped with vacuum pumps to pull air out of the chamber, these chambers are constructed with heavy welded load-bearing ribs to withstand the crushing pressure of ambient pressure on the outside. Special care is taken with proper sealing techniques to prevent air leakage.

The RH-Series includes:

	Standard Altitude control:  Site level to 100,000 ft.
	Temperature control: up to 65,000 ft.
	Standard Temperature Range: -73°C to 177°C
	Optional extended Altitude Range to 200,000 ft.
	Optional Humidity operation to 15,000 ft.
