Abstract:
1. A dew formation testing device for performing dew formation testing, the device comprising: an adjustment unit having a casing in which the adjustment unit adjusts temperature and humidity of air to predetermined temperature and humidity; a testing tank having a casing installed at a place separated from a place where the casing of the adjustment unit is installed, wherein the casing of the testing tank houses a sample base that has a mounting surface, onto which a testing sample can be placed, and that is capable to cool the mounting surface; and a duct linking the casing of the adjustment unit and the casing of the testing tank so as not transmit vibration of the casing of the adjustment unit to the testing tank, wherein the testing tank is provided with an air guide member that, when air flowing into the testing tank through the duct flows onto the sample base from a side of the sample base, guides the air in a direction tilted downward at a predetermined angle, the guidance being performed at a position right above the sample base at an end thereof which is on the upstream side of the air flow, the air guide member decreasing an area of an air flow passage from the upstream side of the air flow toward the downstream side of the air flow.
