Test Chambers

Environmental test chambers are used to evaluate a product's or material's performance under a range of conditions, such as heat, wetness, elevation, vibration, and light. By recreating the conditions under which an item or material will be used, manufacturers may assure that their goods will perform as anticipated in the actual world. The standard testing chambers are created specifically to produce the testing conditions. Additionally, chambers can be used to simulate environments that do not exist on Earth, like the vacuum of space.

Environmental Chamber Types

Environmental chambers come in many designs, each of which is intended to produce a particular set of testing conditions. The following are a few of the most typical types of chambers:

Altitude Chambers

Replicating the gaseous and pressure conditions seen at various elevations, altitude chambers are also known as hypobaric chambers. In altitude chambers, not only are items subjected to simulated high altitudes, but so are human test subjects who are anticipating exposure to changes in altitude and the lower oxygen levels that come along with such changes. This comprises aspiring pilots as well as divers, climbers, and sportsmen. Altitude chambers are crucial instruments in the aviation, aerospace, automobile, and military sectors because to the delicate nature of their technology and tasks.

Cryogenic Chambers

Test chambers that use liquid nitrogen to replicate situations with extremely low temperatures, typically between 0 °F (-18 °C) to -238 °F (-150 °C) or lower. The effects of abrupt temporal shifts as well as high temperatures are studied in temperature chambers, which include cryogenic chambers.

Thermal Shock Chambers

Thermal shock chambers measure how a product responds to rapid temperature fluctuations in terms of stress and strain. They specifically monitor thermal shock, as implied by their name. The conflict caused by uneven component expansion and compression induced during heating or cooling results in thermal shock, which leads to faulting or splitting along lines of stress. Glass and ceramics are particularly susceptible to thermal shock due to their limited heat conductivity and propensity to compress and expand unevenly. This is the rationale behind the widespread usage of thermal shock chambers in a variety of industries, such as construction, medical, aerospace, automotive, and consumer goods.

Pressure Chambers

Pressure chambers, which can endure both high and low pressure situations, are used to test products under various types of extreme pressure. To prevent explosions and malfunctions, the chamber's operation needs to be closely watched. They can replicate pressure at varying ocean depths as well as pressure at high elevations, both static and fluctuating. The chamber's atmospheric pressures can be increased to 60,000 psi or decreased to produce a vacuum.

Vacuum Chambers

In vacuum chambers, air and pressure are removed from an enclosed space so that the materials' reactions to a vacuum may be studied. Regulations for the defense and aerospace industries mandate that items be tested in a vacuum. Vacuum testing is a technique used by spacecraft engineers to examine the electronics, circuitry, optics, filters, and structural components of a spacecraft. Additionally, air bubbles in synthetic resin that will be injected into a mold are eliminated using vacuum chambers.

AGREE Chambers

The letters AGREE means "Advisory Group on Reliability of Electronic Equipment" in AGREE chambers. They have the name of the United States Defense Department team that first established their high requirements. AGREE chambers were first intended to test exclusively military hardware. However, they now offer a combination of vibration, humidity, and temperature testing to applications across a range of sectors. Even with heavy loads, they are capable of producing dramatic temperature fluctuations at rates of between 40 and 107 per minute. Their vibratory properties are based on the floor's detachable feature.

Walk-in Chambers

Large products can be tested and stored in walk-in test chambers. They range greatly in size, with some similar to a small closet and others as huge as a room. They are all big enough for a human to walk into. The tasks of other testing chambers, such as salt spray, thermal shock, and temperature testing, can all be carried out in walk-in chambers.

Choosing the Right Test Chamber Manufacturer

For the most beneficial outcome when purchasing a test chamber from a test chamber manufacturer, it is important to compare several companies using our directory of test chamber manufacturers. Each test chamber manufacturer has a business profile page highlighting their areas of experience and capabilities, along with a contact form to directly communicate with the manufacturer for more information or request a quote. Review each test chamber business website to better understand what each company specializes in. Then, use our simple RFQ form to contact multiple test chamber companies with the same form.
