Psychrometric Chart used in drying your home
Psychrometric Chart
The Psychrometric Chart.
To properly evaluate temperature, relative humidity and grains per pound (or g/kg), restorers must use a psychrometric chart. Typically, a restorative drying technician will acquire a dry bulb temperature (either in Fahrenheit or Celsius) and a relative humidity using a thermohygrometer. These two readings establish the capacity of the air mass (temperature) to hold moisture and the relative amount of moisture in the air (relative humidity).
After acquiring these two readings, the technician can then employ the psychrometric chart to calculate GPP (Grains per pound). Other calculations are also made if necessary. Once these calculation are completed the technician compares them to surrounding conditions or previous conditions to evaluate drying potential.
