What are altitude test chambers for?

Walk-in Altitude Chamber is required for testing components for the aviation market. They are used to reproduce the operating conditions of components or products that will operate at high altitudes, i.e. in environments where the atmospheric pressure level decreases over time.

As altitude increases, pressure decreases: with increasing altitude conditions, both the height of the air column above and the density of the air decrease.
To simulate the exact altitude above sea level, it is necessary to ensure effective combined control of temperature and pressure, and in some cases also humidity.

 

Meet Standards

IEC 62133-2017

Application 
JOEO horizontal thermal test chamber is the best choice for batch testing and large test loads. The interior design is used for custom environmental stress screening of components and board level electronic components. The carrier basket transfers loads between hot and cold zones in two - or three-zone configurations, and is widely used in automotive, electronic and electrical, aerospace, communication equipment, medical equipment and other industries.
