Additional expanded thermodynamic properties are available at each pressure / temperature combination for the following refrigerants:
R12, R22, R23, R32, R123, R124, R125, R134a, R143a, R152a, R170, R245fa, R290, R404a, R407c, R410a, R507a, R600, R600a, R717, R718, R744, R1150, and R1270
Metric and Imperial expanded thermodynamic properties include:
• Bubble and Dew temp
• Pressure (psia / MPa)
• Density of Liquid
• Volume of Vapor
• Enthalpy of Liquid and Vapor
• Entropy of Liquid and Vapor
• Specific Heat of Liquid and Vapor
These properties are available by tapping on the pressure temperature row.
Notes on Refrigerant Blends:
• Bubble and dew points combined on one line for all blends
• R404a, R407c, and R410a key on pressure to better indicate temperature glide
Additional information:
• Chemical Name
• Formula
• Ozone depletion potential (ODP)
• global warming potential (GWP)
• molecular mass
• boiling point
• critical pressure
• critical temperature
Roughly a fourth of the refrigerants have additional information including color code, lubricants, etc.

It was a good app for the price but when my iPhone updated the app is worthless, please take care of your clients and update your app.
I have paid for this app and it’s not being updated, along with several other apps by Kevin Burandt, that were paid for (in good faith) so that they would be maintained by the developer. When will they be updated?!?!
Now I have my pressure conversion charts with me at all times plus it easier to read than the field charts and at 4.99 it is much cheaper buying a decicated digital pressure temperature chart.
Very nice app! Very handy because it breaks down pressures into 1 psig increments.
I agree with the other reviewer it's the only program that has 1 psi increments.
Sweet app. As a commercial HVACR technician/engineer I will be using this on a daily basis. Very well done.
Could we please get and update (or maybe a different chart) for those of us above 5000 ft. all my charts read different than these.
