1. environment test device comprises:

  • Testing laboratory is used to place subjects;

    Wet bulb and dry bulb are disposed in the described testing laboratory in order to detect the humiture of the air in the described testing laboratory;

    Aircondition arrives predetermined humiture according to the signal from described wet bulb and dry bulb with the artificial atmosphere in the described testing laboratory;

    The cooling well heater be accommodated in the described testing laboratory, and described subjects is disposed at its upper surface, and described subjects is carried out cooling;

    The dewfall quantity sensor, mounting is on described subjects;

    AndControl device, between value, change to temperature command value that described cooling well heater sends according to making, thereby the dewfall amount on described subjects surface is controlled by the value of wet-bulb temperature that described wet bulb detected and deviation addition and dewpoint temperature in the described testing laboratory and deviation addition from the signal of described dewfall quantity sensor.
