תיאור
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 (33’)).
Status Indicator: Visible from a distance, LED "halo" light indicates probe is active and transmitting.
Easy to replace battery: The HALO's CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours.
One Button Sample Tagging: Pressing either the button on the HALO™ pH probe or the probe icon in the Hanna Lab App will tag sample data for easy reference.
Integrated Temperature Sensor: Ensures the calibration and measurement is automatically temperature compensated, thus eliminating error.
Stored Calibration Data: HALO™ stores calibration information; no additional calibration is needed when switching to another iPad.
The Hanna Lab App turns an iPad into a full-featured pH meter when used with the Hanna HALO™ pH probe 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 panned and zoomed with the iPad’s pinch-to-zoom technology for enhanced viewing.
Probe calibration using up to 5 buffers: The Hanna Lab App incorporates a probe calibration using up to five pH buffers that are automatically recognized and temperature corrected to 25.0ºC during calibration.
Real-time Data: Display of pH and temperature updated every second. Readings are automatically saved to a history file every hour, limited only by the available memory on the iPad.
Fluid, Dynamic Graphing: Measurement can be displayed with tabulated data or a graph on the display. The graph axes may be expanded using the iPad’s pinch and zoom technology for enhanced viewing.
Connecting the 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. Select the newly discovered HALO™ probe from the list of available probes. If a previously associated probe is in discovery mode when the app is opened it will connect to that probe automatically.
GLP (Good Laboratory Practice): Displays date and time of current calibration, probe offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.
Calibration Reminder & Measurement Alarms: Alerts you when HALO™ needs calibration, and if the measurement threshold is exceeded.
Log & Share Data: Saved log files may be annotated with measurement specific information. Share data via email in CSV format.
Help & Tutorials: Demo probe mode helps you explore features of the Hanna Lab App. General app information, General HALO™information, pH tutorial, maintenance tutorial, and contact information are available in help.
