Description
This comprehensive Pressure/Temperature calculation tool from National Refrigerants provides several unique features designed to make the HVAC/R technician’s job easier. This app can calculate a simple pressure/temperature relationship or calculate superheat/subcool temperatures. The user can input pressure or temperature(s) on any screen and the other values are automatically calculated and displayed. For refrigerant blends, both saturated vapor and saturated liquid values are displayed. Within the superheat/subcool screen, a graphic display for blends will show the entering, mid-point, and outlet temperature as well as line temperature.
Other features include:
- Automatic altitude correction (if location services are enabled)
- English/Metric units
- Easily choose from “favorites” refrigerants list
- Supplementary information about refrigerants and links to NRI website

Ratings and Reviews
Easy to use!
The gauges I bought have saturated temps in Celsius while everything else I have is in Fahrenheit! This app made the process super easy as well as automating the simple math to calculate Subcool/Superheat values.
Great Tool
Great tool with many features most P-T apps don’t have. Helps show glide and calculates superheat / subcooling and many other helpful things.
Best app for blend refrigerants
Have used this app a few times servicing new high glide refrigerant systems and it works great. It compensates for changes in glide temperatures which is very helpful for new refrigerants
