A TEMPERATURE CHAMBER (12, 30, 44) IN WHICH A DEVICE IS TESTED IS CONNECTED TO A TEMPERATURE-CONTROLLED AIR SOURCE (10) FOR CONTROLLING TEMPERATURE OF THE CHAMBER. THE TEMPERATURE CHAMBER INCLUDES THERMAL INSULATION (16, 43, 54) FORMED ON SIDE SURFACES OF THE CHAMBER. A UNIVERSAL MANIFOLD ADAPTOR (20) FOR DIRECTING THE TEMPERATURE-CONTROLLED AIR DIRECTLY TO A DEVICE BEING TESTED IS CONNECTED TO THE CHAMBER. THE TEMPERATURE CHAMBER ALSO INCLUDES AN EXHAUST SYSTEM. A SELF-CLOSING CABLE FEED-THROUGH MODULE (64) IS CONNECTED TO AN OUTER SURFACE OF THE CHAMBER. THE FEED-THROUGH MODULE INCLUDES A FIRST PORTION (68) AND A SECOND PORTION (70), WHEREIN CABLES (66) ARE FED THROUGH THE FIRST AND SECOND PORTIONS INTO THE CHAMBER IN A FIRST POSITION AND THE FIRST AND SECOND PORTIONS FORM A LEAK TIGHT SEAL AROUND THE CABLES IN A SECOND POSITION.
