SENSORS:

• RTD — 100 OHM PLATINUM: Measured at the point of airflow entering the workspace. Class A, 3-wire platinum resistance sensor. Standard on all chambers.
• VAISALA HMM100 RELATIVE HUMIDITY SENSOR: Measured at the point of airflow entering the workspace. Airflow speed does not affect measurement. Highly accurate between 10–95% RH over the entire operating range of −70°C to +180°C (−94°F to +356°F). (Optional)
• TYPE T THERMOCOUPLE: Connects to the limit controller for safety monitoring. (Additional Purchase)
• HIGH HUMIDITY HEATED SENSOR: Replaces the standard RH sensor and enables testing up to 98% RH. The heated probe prevents condensation and maintains accuracy across high humidity, vacuum, and pressurized environments. (Upgrade Available)

PANEL WALK-INS COME IN VARIETY OF SIZES AND SHAPES OFFERING COMPLETE FLEXIBILITY

STABILITY WALK-IN CHAMBERS

When products need to be tested or stored in a constant environment, stability chambers will replicate such conditions.

Stability chambers are meant to run constantly for long periods of time at a consistent temperature with or without humidity.

These steady-state chambers are electronically configured to meet several governmental regulations and test requirements in industries such as electronics, healthcare, food and beverage, packaging, life science, and more.  Chambers are always factory set and configured to meet your specific test requirements, and a service team member can calibrate the chamber to ensure accuracy.

Below are common sizes manufactured at Associated Environmental Systems in Acton, Massachusetts.  We are known for building custom stability chambers which meet our customers specifications with the same manufacturing lead times as standard chambers.

WALK-IN PERFORMANCE CHAMBERS 

Performance chambers are used for iterative testing where conditions fluctuate. 

Chambers are available in more than two dozen sizes and can be combined with many power packages.  Below is a small sampling of our most common chamber sizes with associated power packages to help you understand the performance options available to you.  The matrix allows you to choose by size or by performance needs.

Extended performance test chambers are typically constructed using solid structure walls due to pressure created within the workspace.  Unique circumstances can apply to allow extended performance capabilities within a panel test chamber, discuss your options with AES sales and engineering team members to specify your needs. 

*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.

*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.

APPLICATIONS & USE CASES

The WR Walk-In Series is highly customizable, depending on the product you are testing. Engineered as large-scale environmental rooms for full-size assemblies, server racks, satellites, and production-scale payloads, the WR Series is offered as both stability walk-ins (steady-state, long-duration conditioning) and performance walk-ins (iterative thermal cycling). Dimensions, door configurations, live-load capacity, floor loading, temperature and humidity ranges, ramp rates, pass-through ports, and controls are all tailored to the application.
