ENVIRONMENT TESTING APPARATUS CAPABLE OF CONTROLLING CONDENSATION AMOUNT, AND CONTROL METHOD THEREFOR

摘要

Provided is an environment testing apparatus with which it is possible to obtain stable condensation conditions at the surface of a test object, with the changes in condensation amount being smaller than in the past. The environment testing apparatus (100) includes a regulator (4). On the basis of a signal from a condensation amount sensor (9), the regulator (4) maintains the temperature of a cooling/heating plate (6) between the wet-bulb temperature obtained from a wet bulb (11), plus deviation, and the dew-point temperature inside a test chamber (1), plus deviation.
