Environmental Chamber

Controlled temperature and humidity testing can be used to analyze how materials react to varying environmental conditions. All products are subjected to a series of conditions through their lifespan of manufacturing, shipping, retail, and end-use. Environmental influences can lead to phase transitions, corrosion, drying, hydration, evaporation, heat treatment, and more, which influence a product’s properties and performance. Knowing the material limits for products allows manufacturers to ensure reliability for their product’s entire lifespan. Ebatco’s Tenney Environmental Chamber controls temperature and humidity for long-term stability, shelf life, and environmental effect testing.
