HALO® is the world’s first professional pH probe with Bluetooth® Smart technology (Bluetooth® 4.0). HALO pH probes feature a built-in temperature sensor and can be used virtually anywhere: in the field, laboratory, or classroom. Their versatility and ease of use will revolutionise the way pH is measured.

All readings are transmitted directly to a compatible smart phone or tablet running the Hanna Lab App or edge®blu.

The Hanna Lab App, available on iOS and Android, turns a compatible smart phone or tablet into a full-featured pH meter when used with a HALO pH probe 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 panned and zoomed with pinch-to-zoom technology for enhanced viewing.

5 HALO Models to choose from:

The HI11312 HALO has many features that makes it ideal for use in a wide variety of applications. These features include general purpose (GP) glass, spheric bulb, integrated temperature sensor, glass body, and double reference junction with silver-free electrolyte.

The HI11102 HALO has many features that makes it ideal for laboratory use. These features include general purpose (GP) glass, spheric bulb, integrated temperature sensor, glass body, and double reference junction with silver-free gel electrolyte.

The HI12302 HALO has many features that makes it ideal for use in the field or on the production floor. These features include general purpose (GP) glass, spheric bulb, integrated temperature sensor, PEI body, and double reference junction with silver-free gel electrolyte.

The FC2022 HALO has many features that makes it ideal for measuring food related products. These features include: low temperature (LT) glass, conical bulb, food grade PVDF body, and open junction with viscolene gel electrolyte.

The HI10482 HALO feature Hanna’s Clogging Prevention System (CPS). This electrode has a unique ground glass junction coupled with a PTFE sleeve to prevent particulates within a sample from clogging the junction. The calibration features of the HI10482 HALO electrode are of great benefit to winemakers. Generally, a pH between 2.9 and 4.0 is optimal for most wines. To increase accuracy and ensure the expected readings are bracketed between the calibration points, pH 3.00 calibration buffer is displayed in lieu of pH 4.01 buffer when this application-specific HALO is connected to the Hanna Lab App or edge blu.
