PROBLEM TO BE SOLVED: To provide a testing device capable of exposing the whole of a workpiece fed into a testing vessel to a gas of constant temperature/constant humidity, and capable of uniformizing a temperature distribution and a humidity distribution in the testing vessel. SOLUTION: A testing chamber 2 is partitioned into the testing vessel 5 and a gas supply vessel 6 by a partitioning wall 4. The partitioning wall 4 is formed with a gas diffusing port 17 for supplying the gas of constant temperature or/and constant humidity to the testing vessel 5, and gas suction ports 18, 19 for sucking the gas from the testing vessel 5. The testing vessel 5 is arranged with the first and second gas feedback ducts 21, 22 having tip openings 21a, 22a arranged in the vicinity of a front wall 9 inner than horizontal guide rails 12, 13, and having rear end openings connected to the gas suction ports 18, 19. Consequently, the gas supplied from the gas diffusing port 17 is fed back after passed through the horizontal guide rails 12, 13 to reach the vicinity of the front wall 9. The whole of the workpiece is thereby exposed to the gas, on the horizontal guide rails 12, 13. The temperature distribution and the humidity distribution are also uniformized in the testing vessel 5. COPYRIGHT: (C)2009,JPO&INPIT
