Environmental test chamber for simulating high altitude environments combined with temperature and humidity control for simultaneous environmental testing

Combining altitude simulation with precise temperature and humidity control, these chambers offer a way to recreate demanding environmental conditions in one space. They are used to study how products and materials react to pressure drops and climate extremes that can occur during transport, storage, or operation at high elevations.

What industries typically use altitude test chambers?

Altitude test chambers are widely used across sectors such as electronics, automotive, aerospace, and pharmaceuticals. These chambers help evaluate how materials and components perform when exposed to combined environmental stresses like low air pressure, extreme temperatures, and controlled humidity. They are essential for applications requiring validation under high-altitude or transportation conditions.

How is an altitude test chamber different from a standard temperature and humidity chamber?

Unlike conventional temperature and humidity chambers, an altitude test chamber can also simulate reduced atmospheric pressure. This capability allows it to recreate high-altitude environments, or the low-pressure conditions encountered during air transport. Combining pressure, temperature, and humidity control in a single system provides more comprehensive testing for product reliability and safety.
