One has thin muslin wrapped around it and is kept wet; it is called a wet bulb thermometer. Aviation dictionary, Wet Bulb Globe Temperature The Wet Bulb Globe Temperature (WBGT) is a composite temperature used to estimate the effect of temperature, humidity, and solar radiation on humans. For temperatures below 5C, where the moisture content of air is very low, the psychrometer does not give reliable results. The cell is defined as the fundamental, functional unit of life. Views expressed here do not necessarily reflect those of Biology Online, its staff, or its partners. an instrument for measuring the humidity and temperature of the air. In the aspiration psychrometer (Figure 1), the thermometers are placed in a special holder, which protects them against damage and the warming effect of direct solar rays; a fan is used to ventilate the wet bulb with the air being studied, at a constant rate of about 2 m/sec. The psychrometer consists of a dry-bulb thermometer and a wet-bulb thermometer. Electric versus Gas: What is your real heating cost? A device comprising two thermometers, one a dry bulb, the other a wet or wick-covered bulb, used in determining the moisture content or relative humidity of air or other gases. One of the most important factors in determining the effectiveness of evaporative cooling is the deltathe wet bulb depression- between the dry bulb and the wet bulb temperature. psychrometer, the thermometers are fastened to a special frame at a weather shelter. Because heat is used in evaporation, the drier the air whose humidity is being measured, the lower the reading of the wet-bulb thermometer.
