Product Description

Combined Altitude & Temperature Environmental Test Chamber is mainly used in aviation, aerospace, electronics, national defense, scientific research and other industrial sectors to determine electrical electronic technology products (including components, materials and instruments).

 

The storage and transportation reliability test can be carried out under the single or simultaneous action of high and low temperature and low pressure, and the test piece can be energized to test the electrical performance parameters at the same time.

 

An automatically controlled vacuum system provides a precise altitude simulated condition up to 30000 meters. Available to connect the cable to the electronic performance test.

 

Feature:

1. Formed sheet steel exterior structure.
2. SUS#304 Stainless steel continuously seals welding, interior cabinet cover with vapor-tight liner, excellent vacuum performance.
3. High capacity vacuum pump
4. High efficient refrigeration system
5. Programmable

 

Standard

• UN 38.3
