Hanna Instruments, Inc. Introduces pH Electrode With Bluetooth Smart Technology

HALO pH Probe with BluetoothHanna Instruments announced the release of HALO, a professional pH probe with Bluetooth Smart (Bluetooth 4.0) technology.

HALO is a high-quality, double-junction, refillable glass pH probe with a built-in temperature sensor that can be used virtually anywhere: in the field, laboratory or classroom. Using Bluetooth Smart technology, HALO transmits measurement data directly to an Apple iPad (third generation or newer) running the Hanna Lab App. This combination frees the HALO from cumbersome wires and the need for expensive meters, taking advantage of the widespread usage and versatility of the iPad.


The Hanna Lab App is a free application that turns the iPad into a full-featured pH meter when used with the Hanna HALO pH electrode. Functions include calibration, measurement, continuous 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 with tabulated data or as a graph. The graph can be panned and zoomed with the iPad’s pinch-to-zoom technology for enhanced viewing.

“Part of our philosophy involves making science accessible to the masses,” says Michelle Salisbury, applications manager for Hanna Instruments. “The HALO does exactly that. It has the potential to be a real game changer. It makes it easier and more affordable than ever to do pH measurements. Home users, schools, laboratories — virtually anyone can perform accurate pH measurements with an iPad, the Hanna Lab App and HALO.”

Hanna’s new HALO is available in the U.S., and will soon be available through any of its 43 international sales offices.
