Hanna's extended description

HALO® Wireless pH electrodes make pH testing simple. Take direct soil & soil slurry pH and temperature measurements using the HI-12922 specifically designed for agricultural tasks.

The HALO® has a triple ceramic junction in the outer reference cell, built-in temperature sensor, and a conic pH sensing tip made with low-temperature glass. All readings are transmitted directly to your mobile or tablet device (with Hanna Lab App) or the edge® blu.

HI-12922 HALO® Wireless Soil pH electrode

The HI-12922 HALO® is a glass pH electrode that incorporates Bluetooth Smart (Bluetooth 4.0) wireless technology with an application-specific design. It has many features that make it ideal for use in agricultural applications, specifically in direct soil & slurry measurements.

These features include:

  • Low-temperature (LT) glass, conical tip, glass body, and triple junction design
  • Easily connects 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 HALO’s CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours


  • Bluetooth® Connection – Wire free data transmission using Bluetooth 4 low power technology.

    Compatible with the HANNA Edge Blu® meter, and also allows transmission of pH and temperature data to your mobile phone or tablet in conjunction with the free HANNA Lab App.



    Battery powered – Allows use away from a power source. Batteries are included with all battery operated products.

    Hanna Lab App

    The first app that turns an iPad® or mobile phone into a full-featured pH meter!

    The Hanna Lab App turns an iPad® or mobile phone into a full-featured pH meter when used with the Hanna HALO® pH electrode with Bluetooth® smart technology. Functions include calibration, measurement, data logging, graphing and data sharing. Measurement and logging of pH and temperature at one second intervals start as soon as the probe is connected. Measurements can be displayed alone on the display, with tabulated data or as a graph. The graph can be planned and zoomed with the iPad's pinch-to-zoom technology for enhanced viewing.

    Connecting a HALO® probe to the Hanna Lab App is simple. Tap the Bluetooth® icon in the top-right corner to view all available HALO® probes then press the button on your HALO® probe. The blue halo on the probe will start blinking indicating that it is in discovery mode. Select the newly discovered HALO® probe from the list of available probes. If a previously associated probe is detectable when the app is opened, it will connect to that probe automatically.
