What is a psychrometric reading?
Psychrometric readings quantify the condition of air during drying — temperature, relative humidity, and grains per pound (GPP) of moisture. Recorded twice daily at inlet and outlet of each dehumidifier, plus unaffected reference and outdoor readings. Required by IICRC S500 §12.2.7 drying documentation.
