Publisher Description
The HVAC Psychrometric Chart app is the first truly interactive graphical psychrometric chart for the iPad, and it includes both IP and SI units. It is now optimized for iOS 16.
Using your finger, you can easily plot HVAC and other psychrometric processes on the iPad screen while you are out in the field, save the graphs, and then email the graph and results to yourself or clients. The HVAC Psych Chart app includes the following features and functionality:
1. Displays a fully customizable psychrometric chart in both landscape and portrait modes.

3. Using your finger, you can plot as many points as you want on the screen. As you move your finger around the graph, the psychrometric properties at the top of the screen dynamically update . In addition, you can double-tap a point to display the point properties and then edit them.
4. Create psychrometric processes by plotting points then connecting them with process lines. Also, create custom labels anywhere on the chart.
5. After you have completed creating the chart, you can email a list of all the points and their properties along with a PDF of the chart, itself.
