Test Chamber Controllers

Technician working on a chamber

AES is proud to offer a variety of controllers with our environmental test chambers. From simple push buttons to beautiful touch screen displays, we have the PID controllers to fit your needs. Most of our controllers can be programmed with profiles to run a long test with any variety of conditions that your chamber can handle. 

AESONE Connect

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

You can now monitor your environmental testing away from the chamber. Enabling communication, AESONE XCHANGE is hardware that lives inside your test chamber opening a world of access.

When AESONE XCHANGE is connected to your test chamber’s controller and your company network, you get access to AESONE CONSOLE. A web-based dashboard view lets you monitor your test chamber remotely as a device is undergoing test. The home page is a side-by-side view of the setpoints and current temperature and humidity, and a customizable graph. AESONE CONSOLE software allows you to 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 can 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. 

Using a shared chamber is not a problem with AESONE 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.

Test Chamber Data Loggers

Technician working on a chamber

One of the most important things while running product tests is to record your data for review. At AES, we offer multiple types of chart recorders to give our customers a variety of data recording options. From circular pen chart recorders to a web-based exchange board we can handle any data logging needs our customers have.

AESONE Connect

Description

Specifications

With on-board, multi-year data logging abilities, collect and manage live and historical data. You can view and analyze data with pause and resume control of live plotting.

An interactive activity log records what the chamber calls for and allows you to add entries as you view the events currently being logged. 

Additionally, you can create custom datalog reports that allow you to zoom in on specific data points in a vivid graph or zoom out for an overall understanding of the profile behaviors.  You can look at custom specified date ranges including up to 8 years of data in the on-board archives. 

Custom color settings can be assigned, allowing you ultimate control when you are viewing your graph. Easily share data with collaborators or download the data at any point during or after testing has finished, either as a CSV or TSV file for permanent records.

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)
