Hanna Instruments released Halo, the world’s first professional pH probe with Bluetooth Smart (Bluetooth 4.0) technology. Halo is a 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 iPad (3rd 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 Apple 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,” said Michelle Salisbury, applications manager for Hanna Instruments. “[Halo] 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 United States and will soon be available through any of the company’s 43 international sales offices. These offices provide Hanna customers with local service, support and training and are part of Hanna’s goal to provide an exceptional customer experience.
