Our HALO® Wireless Soil pH Meter has a triple ceramic junction in the outer reference cell, built-in temperature sensor, and the conic pH sensing tip making it ideal for pH measurements in soil samples. All readings are transmitted directly to your Apple or Android device or the edge®blu.
Easily connect to the Hanna Lab App at the press of a button via Bluetooth wireless technology.
Visible from a distance, the LED “halo” light flashes to indicate the status of the probe.
The HALOs CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours.
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 (LT) glass Low temperature glass for fast stabilization and more accurate results at lower temperatures.
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.
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.
Display of soil 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.
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.
Displays date and time of current calibration, offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.
The Hanna Lab App alerts you when HALO needs calibration or if a measurement threshold is exceeded.
Saved log files may be annotated with measurement-specific information. Data is easily shared via email in CSV format.
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.
