Once the calibration has been completed, you can use the sensor (pH probe and EZO pH circuit) in your application.
If the probe is being used in applications such as hydroponics, fish tanks or any environment that generally has levels of weak acid/base then calibrating once per year would suffice.
Currently, the calibration is done via the Arduino serial monitor. Adding buttons for this would be a neat modification!
