Environmental Test Chambers

Twelve walk-in temperature chambers maintain environmental conditions at precise levels. The chambers have temperature ranges from -20°F to 140°F, and humidity may be varied from 25 percent to 100 percent. They control temperature to within + or -2°F and humidity to within + or - 4 percent. Designed to maintain good stability, the chambers are available for either short-term or long-term tests. One of the rooms is fully equipped with computerized control and data acquisition. The system is capable of cycling the environmental conditions and can directly control specimen temperature and humidity (as opposed to simply controlling room conditions) using a feedback system. Provision is also made for control of ultraviolet lighting in this room.

Environmental test cabinets are part of this setup. The Instron Environmental Test System is compatible with the Instron and Gilmore testing machines. In addition, researchers have access to two large (40-inch width x 50-inch height x 22-inch depth), elevated temperature cabinets. They can produce temperatures from ambient to approximately 400°F and are accurate to within + or -2°F. Another temperature cabinet with the same capabilities uses the MTS systems.
