Measuring Wet Bulb Temperature Sciencing

WebDry- and wet-bulb temperatures, measured together, are among the most popular methods for determining the air condition, and from these measurements, other air properties may be derived. Dry- and wet-bulb temperatures can be measured using a variety of instruments, e.g., mercury-in-glass, thermocouple, and resistance thermometers. WebWhile the dry bulb thermometer is measuring what is thought of as ambient air temperature, the wet bulb thermometer is used to calculate relative humidity. To prepare the wet bulb thermometer, distilled water is added to the reservoir of the hygrometer, and this saturates the wick.
