THE MOST COMPREHENSIVE P/T CHART ON THE MARKET IS NOW A UNIVERSAL APP: IT WORKS ON BOTH THE iPAD and iPHONE.This app now includes the HVAC Equipment Locator. Click here for details: http://bit.ly/1yTq539HVAC PT Chart is an electronic pressure temperature calculator that allows HVAC technicians and contractors to quickly look up the temperature and corresponding pressure for 100+ common HVAC refrigerants including both bubble and dew versions of azeotropic (mixture) refrigerants. This is the only PT Chart app that allows you to email complete PT chart lists, refrigerant properties, and your inputted values/results.This is a unique PT Chart app for the following reasons:1. Works on both the Apple iPhone and iPad (and adjusts its screen according to the mobile device screen size, whether you are running it on the iPhone 6 or the iPad)2. Optimized for iOS 83. Includes 100+ refrigerants4. Allows you to input the temperature and then the corresponding pressure will display and vice versa.5. Allows you to also use a slider control to specify the exact pressure or temperature to see the corresponding temperature or pressure6. Displays a list of pressure/temperature values in 1 degree increments7. Allows you to select the atmospheric pressure so as to show the true pressure-temperature relationship even for high elevations8. Includes a database of 1000+ cities world-wide with elevation data that is used to derive atmospheric pressure9. Display common properties for the selected refrigerant (oil type, GWP, composition, critical temp, boiling temp, and more...)10. Email project inputs and properties for the selected refrigerant11. Email the full pressure/temperature list for the selected refrigerant12. Display units in both English and Metric13. Includes both dew and bubble versions of any azeotropic (mixture) refrigerants
