- Maintenance free
- Gel-filled reference with no fill solutions required. Other than routine calibration and cleaning, this probe is maintenance free.
Bottom line
HALO2 is a pH electrode with Bluetooth® Smart technology that allows the use of a compatible Apple or Android smart device used as a pH meter. This BT smart technology is energy efficient, allowing for low power consumption to maximize the life of the replaceable battery used in the pH electrode. HALO2 pH probes can be used virtually anywhere: in the field, laboratory, or classroom. With 15 styles of pH electrodes to choose from, matching a HALO2 to your need is easy for a customized testing experience.
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.
