The Hanna Lab App turns an Android device into a full-featured pH meter when used with a Hanna Instruments HALO™ pH probe with Bluetooth® Smart technology.

The Hanna Lab App includes a Demo mode showing all the features of the app.

The Hanna Lab App provides a display of the current pH measurement, solution temperature and mV reading as well as a graphical plot or tabulated record of measured data over time. The app also features built-in help, probe calibration, manual or interval data logging, data sharing, and alarms when the readings are outside user-defined limits.

The HALO™ probe’s Bluetooth® Smart technology offers many advantages in wireless measurement convenience and the probe can be used up to 10 meters (33 feet) from the Android device. The HALO™ probe and Hanna Lab App are ideal for professionals and educators needing accurate wireless measurements in the laboratory, classroom and in the field.
