Temperature Test Chamber Knowledge

What is a Temperature Chamber?

Temperature chambers are controlled atmospheres capable of creating conditions an item will be exposed to when it is in use. This highly controlled technological equipment can generate the various types of dangers, applications, and conditions that the product might encounter. To determine the longevity of an item, Temperature chambers can produce conditions that mimic a product’s life span by rapidly altering it.

Temperature chambers let companies test how their products react when exposed to extreme conditions. The capability to create these conditions can help introduce a product to the market that is not able to meet the needs of the customer.


How a Temperature Chamber Works?

Temperature chambers employ different techniques to produce the various temperatures to mimic different atmospheric conditions. The differences in the processes are not directly related to the device’s effectiveness but are more in line with the specific processes employed by the manufacturer. Numerous manufacturers offer a variety of methods to meet the demands of their clients.

Temperature chambers measure the lasting effects of temperature variations to determine the quality of the components or parameters. They aid in determining the material’s behavior under extreme conditions, which involve shifting temperatures due to variations in humidity. The tests may be static in time or dynamic to trigger and lead to failure.


Temperature chambers, also called chambers for environmental testing, carry out thermal tests by using the force of air convection. In various ways, they function similarly to ovens. The primary requirement is the flow of air driven by a fan and motor that circulates air through the chamber for testing.


Types of Temperature Chambers

There are various kinds and sizes of chambers for temperature, ranging from those that can be placed on a shelf or which are as big as the building. The primary factors in selecting a temperature chamber are the space available and the ideal conditions to be achieved.

While you can typically buy an ordinary test chamber, buyers collaborate with manufacturers to design an exact chamber that meets the client’s requirements. There are many aspects that every customer would like to test, and the test chamber they select should satisfy those requirements.

They are small in footprint but have a bigger capacity, comparable to benchtops or small test benches. They range in dimensions between 10 cubic feet and 64 cubic feet, with the temperature ranging from the -68 deg C range to 180 deg C. Reach-in test chambers are equipped with an average temperature of +-1.0 deg C.

  • Walk-In Temperature Chambers

The name suggests that walk-in temperature chambers are expansive and are designed to accommodate many or huge components. They can be built modularly and shipped as a single unit or on-site. Most walk-in rooms are custom built to meet the customer’s requirements. Panel walk-in chambers are made of lightweight, insulated panels that are easy and easy to set up as well as solid walk-in rooms have walls that are welded to ensure an ideal seal.

The walk-in temperature chambers are available in various sizes, from 286 cubic feet to chambers with more than 1,400 cubic feet. While these are typical dimensions, most walk-in chambers are custom-created and constructed. Based on the model, they could be temperature-controlled from 40 deg C to 150 deg C.

  • Drive-In Temperature Chambers

The Drive-In temperature chambers are used to test components of automobiles and components as parts of a complete vehicle. Although individual components can be examined in smaller chambers, they also allow manufacturers to study the weathering of components when they are integrated into the final product.

There’s no standard dimension for drive-in chambers like walk-in chambers. They can be tiny enough to fit in small cars or accommodate a large diesel truck. The specifications and dimensions differ from the needs of the automaker.

The differences in size also apply to the other aspects of the chamber. It is possible to say that all test chambers are equipped with PID control systems. In the case of drive-in chambers, the programs in the system could be more precise in the information needed.
