Your company has just developed a great new product, and now it is your job to select an environmental test chamber to test it and make sure it will hold up. Your new product must be tested at various conditions to ensure its quality and reliability. So where do you start? What will determine your selection criteria? Price, quality, capabilities…. As with any major test purchase, several items must be considered before making the final decision on your test chamber. Many people are tempted to buy on price only. However, as we know, you get what you pay for.
When it comes to test chambers, quality, reliability, and service after the sale all add up to the value of your test chamber purchase. Value often is mistaken for low price. Over the life of the test chamber, that can become a costly mistake.
Test chambers feature precise temperature and humidity control to create repeatable environmental conditions. Test chambers are suitable for numerous applications, including product shelf life, stability and package testing, light exposure and temperature evaluation studies, electronic component burn-in, TAPPI testing, plant growth, and insect rearing just to name a few.
Test chambers feature a wide temperature range and relative humidity (RH) ranges and vary from manufacturer. Most modern test chambers feature microprocessor-based controllers with computer communications, autotune, solid state RH sensor, and stainless steel temperature probes. LED displays of temperature and RH during operation show both process and set point values. Environmentally-friendly HFC refrigerant and CFC-free insulation are utilized by most reputable test chamber manufactures of today.
While some companies rely on test labs to do all their testing, such as those operated by Wyle Labs and National Technical Systems, most companies are realizing the customization, freedom and time savings of purchasing their own test chamber equipment so they can test when and whatever they want.
Audible and visual temperature alarms alert the users of any temperature deviation from active set point, or that the high limit has been exceeded. In the event of a power failure, nonvolatile memory allows the test chamber to return to original set point when power is restored.
Make sure to discuss the details of your tests with the manufacturer
