What components does the temperature and humidity Test Chamber consist of?

Accurate testing requires several chamber components. These include air ducts that circulate air throughout the Test Chamber, and a temperature-controlled environment.

A temperature chamber control thermocouple mounted on the ceiling is the required component. Electronic humidity sensors and baffles also control the air. The white arrows indicate the airflow over the product, which then draws air into the chamber.

The humidity system, compressor and condenser are installed in the front cabinet. Many different types of environmental conditions can be simulated using a temperature and Humidity Chamber. Temperature-controlled environments can vary from cold to hot, so the importance of temperature in a temperature and Humidity Chamber cannot be overemphasized. High temperature testing can reveal a variety of factors that can lead to product failure. The components of a temperature and Humidity Chamber are important, but so is the test itself. The various components and materials of the chamber need to be durable and reliable enough to withstand these conditions. In addition, the contents of the chamber need to meet stringent performance requirements.

Once all these components and devices are installed, it's time to start testing. To maintain accuracy, high temperature chambers require periodic calibration. It is common practice to recalibrate chamber controllers at least once a year. Another important consideration when selecting a temperature chamber is its horsepower. More horsepower means the chamber can reach the desired temperature faster. Because the heating process requires constant intake of air, the Test Chamber needs to constantly draw air into its chamber, reheat it, and then push it out. The amount of power required depends on the type of temperature chamber and the device under test. Therefore, the importance of choosing a walk-in Temperature Test Chamber with sufficient power to meet your testing requirements cannot be overemphasized.

Temperature and humidity Test Chambers can be used to simulate various extreme conditions of products and materials. This is especially useful when trying to determine the effect of different temperatures on a product. Temperature altitude Test Chambers can remain static or dynamic over time, resulting in failure or damage. Most Temperature Test Chambers use forced air convection, making them similar to an oven. The airflow is controlled by the temperature chamber's fans and motors.
