Humidity & Temperature Test Chamber: Why Environmental Testing Cannot Be Postponed Your product will not fail because of some general factors. It will fail due to its exposure to heat, temperature variations or humidity in the course of months of usage that were not taken into account while developing the product. That is exactly what the humidity & temperature test chamber takes care of – allowing you to cover years of damage in just a few days. What is the purpose of Humidity & Temperature Test Chamber? In simple terms, what this equipment does is provide controlled conditions of temperature and relative humidity within the test chamber such that the user can analyze the reaction of the product or component in response to these conditions in an external environment. The climatic test chambers operate normally in the range of -40°C to +150°C while the humidity is maintained between 20% RH and 98% RH depending on the specification of the particular chamber. This type of environmental testing is very critical in case of electronics, auto components, packaging, and pharmaceuticals. Combined Testing Is Superior to Individual Testing If individual tests for temperature and humidity are performed, then only half of the puzzle will be revealed. Actually, the reason for the malfunctioning is connected with both of them and is known as combined environmental stress in engineering. In addition, humidity chamber testing may fail to reveal the occurrence of condensation corrosion in case when there is temperature and humidity variation simultaneously, as it takes place with actual products. This is the reason why the modern approach to accelerated life testing is the use of temperature-humidity cycling. It enables obtaining much more accurate results regarding the product’s lifetime. Industries That Use These Machines on a Regular Basis The electronics industry utilizes humidity and temperature chambers to verify the reliability of printed circuit boards (PCB), connector corrosion resistance, and the ability of the enclosure to seal. The automobile components industry uses humidity and temperature chambers to check whether the dashboard material, wiring harness, and sensor housing can withstand varying weather conditions. The pharmaceuticals industry employs stability chambers, which is a special kind of these machines, to establish the shelf-life of its formulations. Factors to Be Taken into Account When Purchasing a Testing Chamber It is crucial to highlight that the uniformity of the chamber is more significant than many people realize since poor air circulation might lead to temperature differences in the chamber. It is recommended to select a test chamber that incorporates a PID controller and permits precise programming of the temperature and humidity levels as well as data logging. Another important issue to consider when purchasing a test chamber is the kind of the refrigeration system that affects its performance particularly at low temperatures. Conclusion The humidity temperature test chamber is not just laboratory equipment; it is a device that can help to foresee any problem that might arise in the future regarding the product. This saves companies from making costly mistakes as it can foresee climate problems even before the product is used.
