What is a Test Chamber and How does it Work?

Have you ever bought a product that turned out to be defective after a few weeks, or even the first time you used it?

This could have happened because some products have been subjected to external factors such as temperature, humidity and vibrations that were not expected or taken into account when they were designed; In addition, we often hear about "quality" and "reliability" as factors that must be taken into account to make the products stand out from the rest.

In the current global market in which each product can be sold in the most remote corners of our planet, it is essential that the development and design phase take into account the different environmental conditions to which the product will be subjected, from warmer climates to colder The effect of salt corrosion, and many other factors.

In addition to the conditions of use, it is good to take into account the various stresses to which the product may be subject during the packaging, transport and storage operations, which could cause damage or shorten the product’s useful life.

Can your product withstand all weather conditions?

Resistance to humidity

It is very likely that, from the first days of your "life", your product is subject to stress factors, sometimes combined, for example:

  • Climate changes
  • Vibrations
  • Solar radiation
  • High humidity levels

So, what should be done to avoid this type of potential drawbacks and ensure greater product reliability? And what guarantees can be given to the client?

The apparently simple answer would be to test the product in all its conditions of use … but how can this be done?

In fact, during the Research and Development phase, many companies perform tests on prototypes to verify reliability, test characteristics, resistance to stress or simply behavior in the context of use. If these tests are not passed satisfactorily, the cause, or defective component, is sought to correct the problem.

To clarify the main characteristics of a climate chamber, ACS has written an article to support the client in the choice of the product. You will find all the information by clicking on the following link: "Practical guide for the selection of a climatic chamber".

The use of an environmental test chamber helps manufacturers to discover possible defects that must be corrected before the production stage, which guarantees:

  • Lower maintenance costs

There are several types of tests that can be performed, with a first categorization that divides them into:

In a test chamber, special conditions can be recreated inside the test compartment in which the prototype to be tested is placed.

To carry out the tests that belong to the first category, a climate test chamber is needed for environmental simulation tests.

How does a climate chamber work?

The operating principle of a test chamber can be explained by the two physical parameters that the camera can control: temperature and humidity.


To control the temperature, the camera must be able to perform two functions: heating and cooling. It must also be able to evenly distribute the temperature inside the test compartment.

The specific technical considerations about the air distribution within the test compartment allow to achieve a great uniformity of the temperature values ​​over time and in all the chamber space, ensuring that all parts and surfaces of the DUT are subject to the same temperature.

The mechanical cooling system of a climatic chamber consists of a closed circuit system, with the following main components:

  • Cycle compressor
  • Condenser
  • Expansion valve
  • Evaporator

By compressing and then expanding a refrigerant gas, the process will uniformly cool the test compartment.
