iqualitrol Desk Type Temperature and Humidity Test Chamber
Brief Introduction:
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,
offer flexibility, uniformity and control accuracy required for
cost effective testing, which perfect for research and development
or personal point-of-use testing.
Available in several sizes, desk type chambers allow you to cost
effectively and select exact chamber that best meets your
environmental test conditions.
