Calibration Procedure
- Portal EC sensors are factory-calibrated, and you can use the calibration solution included in the package to verify the calibration or perform it again if needed.
- After connecting Portal to the app via Bluetooth, you’ll find the calibration page in the app settings.

A Quick Fix
- If you run out of the included solution, you can purchase a laboratory-grade EC standard solution and use that instead.
- As a temporary alternative, you can also use saline. Simply buy saline, measure its EC value with Portal, and keep that value noted for reference.
- Standard solutions gradually become more concentrated over time once they’re opened because of evaporation, so it’s best to keep them sealed and not store them for too long.
