Lab professionals who love Bluetooth will be particularly happy with Hanna Instruments’ recent release of the world’s first professional pH probe with Bluetooth® Smart (Bluetooth® 4.0) technology.

Called HALOTM, the probe’s wireless design and unique rhythmic, blue indicator light is changing how pH is measured. The high-quality, double junction, refillable glass pH probe with a built-in temperature sensor can be used almost anywhere: in the field, laboratory or classroom. And, with its Bluetooth capabilities, it transmits measurement data directly to an iPad (3rd generation or newer) that is running the free Hanna Lab App. That means no wires or expensive meters are required.

“Part of our philosophy involves making science accessible to the masses,” said Michelle Salisbury, applications manager for Hanna Instruments. “The HALO does exactly that. It has the potential to be a real game changer [as 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.”

The app itself allows users to turn their iPads into full-featured pH meters when used with the HALO. That means they can perform calibration, measurement, continuous data logging, graphing, and data sharing on their tablets. Measurement and logging of pH and temperature at one second intervals start as soon as the probe is connected and those 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 better viewing.
