Main Display
This screen is showing pH, millivolts, air temperature and probe temperature.
Temperature can be displayed in Celcius, Farenheight, or Kelvin.

Calibration Display
Three points are shown here. Any number of points can be input for calibration, and the app uses a regression algorithm to calculate the ideal slope and offset.
Every time a measurement is recorded, the calibration that was in effect is saved with the reading for auditing purposes.

History Display
History can be grouped by date or location. The history database is limited only by the free memory in the iPod/iPhone.
If location services are enabled, each record also has the geo coordinates stored.
