About ManTooth

1. Besides displaying live pressure and temperature readings, the Pressure/Temp Session tracks MIN/AVG/MAX pressure statistics, displays vapor and liquid saturation temperatures, calculates superheat and subcooling, calculates target superheat, and allows the user to enter and display a target subcooling value.

2. The Vacuum Session displays live vacuum readings, allows the user to enter and display a target vacuum level, and provides a “Hold Test” function for effective system evacuation.

3. The pressure, temperature, and vacuum readings are displayed, along with key system analysis data, in an easy-to-read format with screenshot and data log sharing capability.

4. Converts pressure, temperature, and vacuum readings to your favorite units of measure, corrects for your elevation using GPS, and can be used with any one of 126 refrigerant profiles built into the app.

5. For automotive applications, enthalpy charting and troubleshooting information for superheat and subcooling readings provide additional diagnostics information.

6. Screenshots and data logs taken on the job will be stored by location and equipment with a date and time stamp.

7. Enter information about each job location and each piece of equipment at that location.

8. Share your screenshots and data logs with others by email, adding other information or attachments as needed.
