The Reets Drying Psychrometric Calculator app has two drying calculators designed for water damage drying contractors to enhance their drying process using their iPhone, iPad or iPod touch: 1) Evaporation Potential Psychrometric Calculator and 2) Minimum Surface Temperature Calculator. For Psychrometric Readings: Do you need to record Grains Per Pound, Vapor Pressure or Dew Point? Simply dial in the surface and air temperatures and relative humidity into the Evaporation Potential Psychrometric Calculator and they are instantly calculated. Evaluation at the beginning of the job: Take surface and air temperatures and relative humidity readings and enter them into the Evaporation Potential Psychrometric Calculator to instantly calculate Dew Point, GPP, Vapor Pressure and Evaporation Potential. Use these numbers to make educated decisions regarding process and equipment placement. Also evaluate surfaces for the potential for condensation. Use the Minimum Surface Temperature Calculator to determine what surface temperatures would be needed to meet drying goals. Monitoring: In addition to calculating Psychrometric Readings, determine whether your evaporation goals have been met. Use the Minimum Surface Temperature calculator to determine if the air is dry enough and the surfaces warm enough to achieve the Evaporation Potential goal that you set. Simply dial in your EP goal and the current air conditions and then check surface temperatures within the structure to be sure that they are warm enough. The Reets Drying Psychrometric Calculator has been developed by Reets Drying Systems, LLC. RDS a leading restoration education firm based near Atlanta, GA, also has IICRC WRT, ASD, CDS, FSRT and Combination courses in addition to Online Training and Systems Building courses.
