PROBLEM TO BE SOLVED: To provide an environmental test device which is capable of dehumidifying air to be taken into a detector with the least increase in power consumption.SOLUTION: An environmental test device 1 can evaluate a sample in a desired environment within a test chamber 6 and is provided with a dehumidifier 2 capable of dehumidifying air taken out from in the test chamber 6, in addition to air-conditioning equipment for forming an environment within the test chamber 6. The humidifier 2 can naturally cool the air by a heat exchanger 22 and can condense and remove water vapor in the air when cooling the air. The air dehumidified by the heat exchanger 22 can be guided to a detector 71 for detecting smoke or the like. Condensed water produced by the heat exchanger 22 can be discharged via a drain pipe 45 arranged above the detector 71. |
