HVAC P/T Chart Calculator

This handy calculator will quickly convert pressure into temperature and calculate Superheat/Subcool for several refrigeration and HVAC refrigerants. No more carrying around a pocket P/T chart or trying to search Google. If your gauge manifold doesn't have the temperature scale for the refrigerant you are working with, just open the app and type in your pressure. The corresponding temperature is instantly displayed. Need to work with Celsius? No problem. Just tap the switch at the bottom of the screen to easily toggle between Fahrenheit and Celsius. Also easily find the Superheat and/or Subcooling by entering the appropriate PSI and line temps. This app currently supports R22, R410a, R134a, R438a (MO99), R407c, R404a, R12, R13, R422D, R502, R152a, R290, R407a, R421a, R422a, R422b (NU22). More refrigerants will be added in future updates. Please leave a review and comment what other refrigerants or functions you would like to see added.
