PT Chart Pack Field Kit: 10 Refrigerant PT Charts, Pocket Cards and Superheat/Subcooling Log Sheets (Printable PDF)
A printable toolbox for HVAC/R technicians and apprentices.
What it does
It has one full page of pressure-temperature data for each of ten refrigerants, with separate bubble and dew columns for blends so superheat and subcooling read from the right one. It adds cut-out pocket cards, a blend-glide reference, and blank log and service-call sheets to print as often as you like. Data is computed with CoolProp 8.0.0 and spot-checked against Honeywell and Hudson Technologies published charts.
