A Sling Psychrometer and Relative Humidity: A Structured-Inquiry Activity A sling psychrometer consists of two thermometers. One is a wet bulb and the other is a dry bulb. To make You may wish to compare this chart with those found in Earth science books or other meteorology publications. All the properties of air indicated in the psychrometric chart are calculated at the standard atmospheric pressure. When at a different air pressure, relevant corrections have to be applied. The psychrometric chart looks like a shoe. The various lines shown in the chart are as followsAuthor: Haresh Khemani.

Apr 24,  · How to Read a Sling Psychrometer Relative Humidity Calculator; About the Author. Corina Fiore is a writer and photographer living in suburban Philadelphia. She earned a charlesrosier.com in Earth-Space Science from West Chester University of Pennsylvania. Fiore taught high school science for 7 years and offered several teacher workshops to regarding. newer electronic meters. The Sling Psychrometer is addressed in ASTM E , Standard Method for Measuring Humidity with a Psychrometer (The measurement of Wet and Dry Bulb Temperatures). It is generally assumed that the most accurate method of determining Relative Humidity and Dew Point is by using a Sling Psychrometer.
