Desk type chambers are suitable for testing small parts, such as semiconductor, computer components, automobile sensors and cellular phone parts.

These chambers combine excellent performance with compact design that is perfect for search and development or personal point-of-use testing.

They also can offer flexibility, uniformity and control accuracy required for cost effective testing. Available in several sizes, desk type chambers allow you to cost effectively and select exact chamber that best meets your environmental test conditions.
