800L Constant Climatic Test Chamber Antiwear Stainless Steel SUS 304

A climatic chamber involves testing and exposing products to various environmental conditions in a controlled setting. Climatic Chamber testing and Thermal Shock testing are part of chamber testing. Climatic Chamber involves a variety of ways to simulate climate or excessive ambient conditions exposure for a product or a material under laboratory-controlled conditions. Thermal Shock testing is used to simulate how materials will react when exposed to changes in extreme climatic conditions, such as going from extremely cold to extremely hot conditions in a very short period of time.
 

The conditions that products may be exposed to in a climatic chamber include extreme temperatures, sudden and extreme temperature variations, altitude, moisture or relative humidity, electrodynamic vibrations, electromagnetic radiation and more.

Manufactured samples, specimens, or components are placed inside the environmental chamber and subjected to one or more of these environmental parameters to determine reliability or measure after-effects such as corrosion. Many chambers are set at a certain set of conditions. Others can be programmed to cycle through specified sequences of conditions.
 

In most climatic chambers, heat is generated by resistive heating elements. Larger environmental chambers have self-contained refrigeration systems to provide cold conditions, while smaller units often rely on external supplies of liquid nitrogen (LN2) or liquid carbon dioxide (CO2) for cooling.

To simulate the corrosive effect of the sea, for example, researchers spray a salt solution through a nozzle inside the chamber, creating a fine mist covering the entire product. The humidity in the test chamber can be simulated either by evaporating the water with a heat source or with ultrasound technology.
