title: A climate room for precise regulation of temperature and humidity in connection with a temperature-regulated nest site for wood ants.
abstract: A climate room is described for precise regulation of temperature and humidity. Humidity is regulated by regulation of the dew-point temperature of the air. The ranges for both dew-point and air temperature are from 2°C to 45°C. The precision of regulation for the temperature is ±0.05°C, for the dew-point temperature ±0.1°C. In the climate room very homogeneous temperatures can be obtained (±0.1°C). The relative humidity is homogeneous within ±1%.It is also possible to make air temperature different from floor temperature. The dimensions of the experimental room are 200×50×17 cm.A temperature-regulated nest site for Red Wood Ants is also described.
