Temperature and Humidity Chambers

Russells Technical Products temperature and humidity test chambers provide a wide range of testing capabilities for product reliability, with high or low temperature configurations. Our temperature and humidity test chambers are available in pre-engineered and custom sizes, providing users the flexibility and convenience to meet their exact testing specifications and requirements. Contact us today to learn more about our temperature and humidity chamber testing capabilities.

Altitude Test Chambers

Altitude or pressure testing is essential for military, industrial, aviation, and consumer applications where products or components experience low-pressure environments or need to withstand rapid decompression in combination with climate control. Russells RH (reach-in) and WH (walk-in) Series altitude chambers offer the performance, flexibility, and reliability required for today’s mixed environmental testing standards. An RTP altitude chamber controls the temperature environment for product testing while simulating various altitudes, or can be used for stand-alone temperature and humidity testing. Russells can manufacture your chamber to meet MIL-STD, RTCA DO-160, and other test specifications.

Battery Test Chambers

Our battery test chambers are equipped with safety features conforming to industry safety standards enabling testing to a variety of conditions and specifications including extreme temperature cycling, humidity, vibration, and/or altitude. Our environmental chambers for battery testing are used in a wide range of battery testing applications including lithium ion, battery packs, lead acid batteries, modules, and more. Whether you need a reach-in chamber for smaller applications, a walk-in, or a complete drive-in, our battery test chambers are designed to safely test to your exact specifications.

AGREE Chambers

Originally designed for the military, the AGREE method of testing, an acronym for The Department of Defense Advisory Group on Reliability of Electronic Equipment, is used to perform reliability, qualification, and ESS for many industries including electronics, automotive, and telecommunications equipment. Offered in a variety of custom sizes and configurations, our AGREE vibration compatible chambers directly integrate with your electrodynamic or mechanical shaker systems, providing you flexibility in choice and testing capacity.

Thermal Shock Chambers

Russells Technical Products offers a wide range of standard and custom thermal shock chambers. Thermal shock or thermal cycling allows for the rapid transfer of products between temperature extremes, or the alternating heating and cooling of test articles in cyclical manner. Our direct transfer method between two independently controlled hot and cold chambers is an economical way to achieve rapid temperature transition or thermal cycling for industries including battery, automotive, aerospace, materials and composites, and more.

Specialty Environmental Chambers

Russells Technical Products offers a wide range of custom and specialty test chambers for a variety of unique testing requirements. Our custom test chambers are designed to meet your exact specifications for industries including battery testing, aerospace and defense, industrial heating and freezing, and more. Contact us today to learn more about our specialty and custom environmental test chamber capabilities.


Russells Technical Products offers both proprietary and off the shelf datalogging and programmable controllers for monitoring, programming, and interpreting your testing. We offer the flexibility to customize your chamber with any one of our offered controllers, or an external controller of your choice. Whatever your preference, our controllers allow for precise control of data monitoring from any location to improve your testing accuracy and efficiency. Contact us today to learn more about our controller capabilities.

Environmental test chambers are critical pieces of equipment across industries, ensuring safer, stronger, and longer-lasting products through repeated exposure to extreme environmental conditions. The ability to produce these conditions within your facility provides flexibility and efficiency in delivering your products to market. 

Most testing applications can be satisfied with our standard environmental test chambers, which are offered with pre-engineered dimensions, performance specifications, and features that provide effective and often economical testing capabilities.

In some circumstances, the product being tested or the test itself requires a unique solution. These particular cases are accomplished with custom environmental chambers designed to meet exact and specific test specifications and requirements. 


When standard features and performance are insufficient, a custom environmental test chamber can be the right solution. Selecting the right equipment can be a challenge, so consider the following four specifications when determining whether a custom chamber might be required for your testing.


Performance is often the first consideration when buying an environmental test chamber. Your test specifications determine temperature, humidity, and altitude requirements and change rates. Identifying your test profile will provide your manufacturer with valuable information in determining the compressor size and configuration required to achieve those defined parameters. A more powerful compressor package might be required when you need to achieve an elevated temperature ramp rate or pulldown. 


The operating conditions under which your products need to be tested will dictate the level of heating and cooling customization. A standard environmental test chamber can operate within the range of -70°C to 180°C (-94°F to 356°F) with cascade refrigeration. 

Optimizing temperature and humidity within that range is accomplished through a circulation system designed to move conditioned air evenly across the interior workspace. A standard cooling system might incorporate a self-contained mechanical refrigeration system with an air-cooled condenser.

A custom chamber that offers further temperature extremes (and temperature change rates) can be accomplished with boost cooling using liquid nitrogen (LN2) or carbon dioxide (CO2). 


The size of the unit under test (UUT) plays a critical role in chamber selection. While a REACH-IN ENVIRONMENTAL TEST CHAMBER might accommodate a wide testing variety, larger devices require a unique layout and design.

Your chamber manufacturer will help to navigate the number of products being tested at one time, the mass and materials of the UUT, the size and dimensions of the UUT, as well as its fixture requirements. A custom environmental test chamber can be designed to contain a unique component or sub-system, all the way up to a hangar-sized enclosure for walk-in or drive-in applications. 


Unique features and requirements can be a significant component of buying a custom environmental chamber. Door configurations, for example, can be offered in hinged, bi-parting, or vertical lift (guillotine-style) in virtually any size. Your manufacturer can offer access ports in limitless sizes, configurations, and quantities, while portable or remote conditioning can be accomplished through insulated ducting. Intrinsic safety features like fire suppression, gas detection, and sheath-limited heaters can be added to customize a TEST CHAMBER FOR BATTERY TESTING.  


The right environmental chamber manufacturer will walk you through the selection process to determine the best fit for your testing operations. Because environmental chambers are used in almost every industry imaginable, the best manufacturers will have the right solution for each unique application.

Prompt and regular communication from the initial request to product selection, order, and delivery should be expected, and the more complex the system, the higher level of involvement will be required through design and engineering to ensure efficient and timely delivery of a quality environmental chamber. 

Need a custom solution? The benefits of custom environmental test chamber design allow for unique building infrastructure and installation considerations where restrictions may limit normal facility access. Ultimately, a custom chamber design process is unique to each customer and application. The best custom environmental chambers are those designed and manufactured to meet your unique test requirements with reliability and longevity so your customers can be confident in your products.
