We’ve taken the traditional paper P/T chart you’ve relied on for so many years and adapted it for the technology of today. The Chemours Pressure-Temperature calculator mobile app gives HVACR service technician’s handy and accurate refrigerant data on the go, enabling quick and reliable system diagnostics and response. Refrigerant options on the app include all major refrigerant products including our recently commercialized Opteon™ HFO refrigerants, as well as their Freon™ HFC and HCFC incumbents. Data available for each refrigerant includes: % composition, physical, chemical, environmental properties, temperature glide, typical use applications and lubricant recommendations. The Chemours PT Calc will display the corresponding pressure when a temperature input is given or provide the temperature for a given pressure reading. For refrigerant blends, both the saturated vapor and saturated liquid values are provided. The user can specify the data in either English or metric units. In addition, the Chemours PT Calc also quickly calculates the superheat and/or subcooling from an operating system based on input from the service contractor in the field, allowing quick and accurate charging, start up, and/or troubleshooting HVAC systems. This is a free app from Chemours.

Better then a paper chart

I love this app. I would like to see my refrigerant selection auto select to all sections. And for it to remember my entries if the screen goes to sleep. I'd also like to see a way to favorites refrigerants. Since I only work with R-22, R-410a and occasionally MO99. Work in target superheat calculation and this would be the only app I need on a daily basis.
