- 0.00 to 12.00 pH range
- Rugged PVDF electrode body
- Easy pH electrode cleaning
- A removable sleeve allows for cleaning, disinfecting, and refreshing (with supplied gel electrolyte) of the outer reference area.
- Conical tip electrode
- Allows for easy penetration into soil or soil slurries.
Benefits
Turn your smart device into a full-featured pH meter.
Connect to the Hanna Lab App at the press of a button via Bluetooth® wireless technology (10 m range (33’)). Hanna Lab App features data, app information, general HALO information, pH tutorials, and contact information.

Sort and share your data. pH and temperature measurements are updated every second and automatically saved every hour. Measurements can be displayed alone on the display, with tabulated data, or as a graph. Push button on demand highlights your data of interest and data points can be annotated with measurement specific information. Share your data via email in PDF or CSV.
Increase traceability. Ensure that your data can be trusted with Good Laboratory Practice (GLP) information including probe offset and average slope of the last calibration. The Hanna Lab App can also be used to set alarm thresholds and calibration reminders.
