AES|XCHANGE by Associated Environmental Systems is a digital data logger and more available to use at the test chamber, on your desktop, or remotely via laptop or tablet. Learn More about all it can do.

Standard on all FD, HD, SM, SD, BHD, & Walk-In Series Environmental Test Chambers

Now you can monitor your environmental testing away from the chamber. AES|XCHANGE Dashboard enables you to view and operate your chamber on a full-screen monitor at your desk or remotely on a laptop or tablet. View real-time readings and control your chamber's temperature and humidity.  A full-screen-mode graph allows you to view and monitor live and historical data with a pause-and-resume feature while the chamber is running a test profile. 

From a web browser, you have the ability to move between profiles, create new profiles, edit and save them.  The Profile Builder uses an easy drag-and-drop interface that makes choosing steps and rearranging test profile steps a breeze.  Say goodbye to spending hours standing at a small screen in front of the chamber building test profiles or using an overcomplicated interface.

 Using a shared chamber is not a problem if you are using ASE|XCHANGE Security features which decrease test interference with three authentication methods and six permission levels controlled only by the administrator.  

Dimensions:  Embedded software allows you to work on a full screen at your desktop or remotely on a laptop or tablet.  Ask for the optional touchscreen monitor to mount on the chamber for full-screen access or plug your laptop in when you're working at the chamber.

Analog Inputs: up to 24* (dependent on controller configuration)

Networking: Ethernet, JSON API, python scripts

Data Storage: Internal flash memory

Capacity before Reset: up to 8 years of continuous recording* (dependent on data logging settings)
