About Environmental chambers - XCH Biomedical Dec 05, 2022
Environmental chambers have been used to research products for decades, with countless applications in aerospace, artificial intelligence, automotive, electronics, solar cells, medical, industrial, and consumer research. In these industries, samples or materials to be tested must be exposed to defined changes in environmental factors in order to study their effects and even prepare for future research.

The conditions that an environmental chamber can replicate are: temperature set point (or change), relative humidity or moisture in the form of rain, electromagnetic radiation, vibration, weathering, salt spray, sun exposure/UV degradation, and vacuum. The type of testing involved will determine the chamber type; chambers come in a variety of sizes and are designed with different features and options.

Environmental chamber humidity control and specimen incubators Prepared specimens or materials are placed in chambers and then subjected to specified levels of environmental stimuli to determine how responsive they are. The resulting by-products were also measured and studied.

Chamber of Commerce Type
Humidity or temperature chambers are used for climatic testing, while vibration and stress chambers are often used for mechanical testing, such as evaluating a product's performance under vibration or shock. "Pressure" is usually tested using a pressure variable or a vacuum.

Stress and vibration chambers are also used in electronics, solar or fuel cells, and automotive products, where testing requirements are very demanding. The goal is to go beyond "normal" to measure the limitations of materials.

Highly Accelerated Life Testing, formally known as HALT testing, is used to discover potential defects and ultimately improve products at the design stage. The chamber will simulate various stimuli such as vibration, aging, humidity, voltage and thermal cycling, which can cause many flaws in design or production.

Instead, a compliance test known as HASS (Highly Accelerated Stress Screening) is performed during production to identify defects prior to commercialization. These tests use temperature and humidity variables to find potential defects.

Environmental test chambers for manufacturing and production have been used for decades and are capable of generating pressures far greater than normal for commercial products.

chamber design
Environmental chambers can be designed as walk in environmental chamber, bench-top, floor-standing, reach-in or drive-in configurations. Depending on the function they perform, they can range in size from portable devices to gigantic rooms, such as the vacuum chamber at NASA's Space Power Facility, which is the largest of its kind.

Floor-standing and table-top darkrooms are the most widely used. While most chambers are made of steel, the materials used for the inner and outer walls vary by application. When used in food packaging or pharmaceutical applications, the chamber may have glass doors for visual access. The intended application of the chamber also affects the types of heaters, coolers, condensers, evaporators, controllers, sensors and other modules used. Newer test chambers have evolved to keep pace with product testing requirements, such as those used in biological and military applications. These chambers are usually custom-made to meet all necessary environmental testing requirements and the equipment used for the measurements is very accurate and reliable.

The newer design of the photostable stability chambers in pharmaceutical has a smaller footprint and is easier to handle than its predecessor. Their user interface resembles a touchscreen Windows monitor rather than traditional scrolling electronics. If they are network enabled, they can be programmed and operated online
