Below is a list of Environmental Test Chambers manufacturers from New Prague, Minnesota. Environmental test chambers reproduce environmental conditions within a contained space for the purposes of evaluating the long-term effects of specific changes upon objects such as industrial products and materials, electronic products and other components. These conditions simulate those which a product will typically encounter in the span of its useful life. Test results can show the process of product decay and degradation and help predict the potential lifespan of a product or material.
