Hanna Lab App The first app that turns a tablet or mobile phone into a full-featured pH meter!
The Hanna Lab App turns a tablet or mobile phone into a full-featured pH meter when used with the Hanna HALO® pH electrode 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 planned and zoomed with the tablet or mobile phone's pinch-to-zoom technology for enhanced viewing.
Connecting a HALO® probe to the Hanna Lab App is simple. Tap the Bluetooth® icon in the top-right corner to view all available HALO® probes then press the button on your HALO® probe. The blue halo on the probe will start blinking indicating that it is in discovery mode. Select the newly discovered HALO® probe from the list of available probes. If a previously associated probe is detectable when the app is opened, it will connect to that probe automatically.
One press Connect Easily connect to the Hanna Lab App (required for use) at the press of a button via Bluetooth® wireless technology (10 m range).
Integrated Temperature Sensor Ensures the calibration and measurement is automatically temperature compensated, thus eliminating error.
