An important aspect of the development of products is the determination of a product’s life cycle, endurance, strength, and resilience. Although it is possible to test them in real time conditions, such testing takes time, expense, and may lack reliability. Walk-in test chambers play a key role in determining the quality of a product and its service life in controlled conditions that can be manipulated and adjusted to imitate any environment.

With a walk-in test chamber, engineers can create conditions that a product may encounter. They allow companies to customize their products to meet the environments of different parts of the world and provide data regarding the stability of the components of a product. Although walk-in test chambers can be initially expensive, the data and information they provide eliminates the disasters associated with the failure of a product.

Stability Walk-in Test Chambers

Stability walk-in test chambers are designed to maintain a steady, consistent temperature and humidity level in a controlled environment for an extended period of time. They use a combination of heat and cooling with water to replicate conditions. For humid conditions, water is heated to create steam that is pumped into an airtight walk-in test chamber. This factor is not present for temperature only chambers. Depending on the quality of a walk-in test chamber, the level necessary to test a product may take a while to achieve.

Once the necessary levels are reached, they are maintained to assess how well a product or device is capable of withstanding the created conditions. For testing products against cold temperatures, fans are used to blow in cold air. The key to creating both sets of conditions is a tightly sealed walk-in test chamber.

The quality testing provided by walk-in test chambers helps manufacturers to develop products that are resilient, strong, and long lasting. Testing the stability of a product helps determine the life expectancy of a product and its shelf life.

Features of Stability Walk-in Test Chambers

• Temperature Reliability – The value of a stability walk-in test chamber relies on the reliability of its temperature controls. Humidity and temperatures must remain constant to determine durability and shelf life. The most effective chambers have temperature variations of ±0.5°C with a temperature range between -20°C to 94°C (-4°F to 201°F).
• 
  
• Humidity Range – Humidity should range between 20% RH and 95% RH (relative humidity) with specialty chambers having a range as high as 98% RH. The inclusion of a desiccant air dryer can extend humidity levels to as low as 5% RH.
• 
  
• Cooling System – The cooling systems for most walk-in test chambers are the same. They are highly durable and consist of self-contained, compact, mechanical, single-stage refrigeration systems.
• 
  
• Remote Monitoring – As with many aspects of modern manufacturing, stability walk-in test chambers can come with remote monitoring devices, which makes oversight of stability testing less labor intensive. Engineers can step away from a walk-in test chamber and still be able to monitor testing conditions.
