HALO® Wireless Soil pH Meter

The HALO^® Wireless Soil pH Meter incorporates Bluetooth^® Smart technology with an application-specific design. There are several features that make it ideal for measuring the pH of soil.

Low-Temperature Glass Formulation

Low Temperature (LT) glass Low-temperature glass for fast stabilization and more accurate results at lower temperatures.

Triple Ceramic Junction

The triple ceramic junction allows a higher flow rate of electrolyte from the reference cell into the measurement sample. The increased flow provides greater continuity between the reference electrode and the indicating electrode.

Conical Glass Tip

The conical-shaped tip design allows for penetration into solids, semi-solids, and emulsions. The HI12922 is ideal for the direct measurement of pH in soil and soil slurries.

Real-Time Data

Display of pH and temperature updated every second. Readings are automatically saved to a history file every hour, limited only by the available memory on the device.

Fluid, Dynamic Graphing

Measurements can be displayed alone on the display, with tabulated data, or as a graph. The graph can be panned and zoomed with pinch-to-zoom technology for enhanced viewing.

GLP (Good Laboratory Practice)

Displays date and time of current calibration, offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.

Calibration Reminder & Measurement Alarms

The Hanna Lab App alerts you when HALO needs calibration or if a measurement threshold is exceeded.

Log & Share Data

Saved log files may be annotated with measurement-specific information. Data is easily shared via email in CSV format.

Help & Tutorials

Demo mode helps you explore features of the Hanna Lab App. General app information, HALO information, pH tutorial, maintenance tutorial, and contact information are available in help.
