Custom-built Walk-in AGREE Thermal Vibration Chamber with Humidity
- What is an AGREE CHAMBER ?
AGREE chambers are environmental test chambers that combine
temperature and humidity testing (optional) with vibration testing.
They are capable of generating rapid temperature changes,
reproducing a variety of humidity levels and can become vibration
chambers when seamlessly integrated with an electrodynamic shaker
or repetitive shock vibration table. Such a design diversifies the
chamber’s utility because it can be used not only as a standalone
temperature environmental chamber but also for combined
The AGREE method of testing is an acronym for The Department of
Defense Advisory Group on Reliability of Electronics Equipment.
Originally designed for the defense and aerospace industry to
perform temperature, humidity, and vibration tests conforming to
MIL-STD 781 and 883, but now more generally used in many other
ATMARS AGREE Test Chambers provide the flexibility to adapt to your
ever-changing environmental testing and industry requirements. Our
AGREE chambers are available in temperature-only or temperature and
humidity configurations with mechanical, electrodynamic and dual axis vibration systems. And rapid thermal change rates of 1°C/min. up to 30°C/min. (average or linear temperature change rate) are available.
Our ATVH series AGREE Vibration Chambers have been adapted to
perform reliability, qualification and Environmental Stress
Screening (ESS) for a wide range of industries, such as
electronics, defense, aerospace, automotive, telecommunications,
batteries and so on.
