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 environmental testing. 

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 industries.

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.
