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.

| Specify your needs, and an Associated Environmental Systems Engineer will work with you to calculate your needs for temperature system or a dual temperature and humidity system. The gray ranges in the chart are the most common. However, other configurations are available. | ||
* Temperature and humidity at sensor † Additional WidthxDepthxHeight configurations available
*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.
