Take the complexity out of testing
HALO2 Wireless pH Meter with Bluetooth® Smart technology (Bluetooth® 4.0) is updated with a dual-level LCD and temperature measurement for automatic temperature compensation. HALO2 pH probes can be used virtually anywhere: in the field, laboratory, or classroom. Their versatility and ease of use will revolutionize the way pH is measured
Connect seamlessly to the Hanna Lab App via Bluetooth wireless technology and with our open-API software our HALO2 series can integrate directly with your current Laboratory Information Management System (LIMS).
One Button Sample Tagging
Pressing the button on the HALO2 pH probe or the probe icon in the Hanna Lab App will tag sample data for easy reference.
Easy to Replace Battery
HALO2’s CR2032 lithium ion battery is easily replaced and lasts for approximately 1,000 hours.
HALO2 can be placed right into our calibration buffer sachets for easy calibration. Using a Hanna calibration sachet ensures your buffer is always fresh.
Hanna Lab App
Available on iOS and Android
The first app that turns a smart phone or tablet into a full-featured pH meter.
The Hanna Lab App turns a compatible smart phone or tablet into a full-featured pH meter when used with HALO. 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, with tabulated data or as a graph. The graph can be panned and zoomed with pinch-to-zoom technology.
Hanna Lab App Views
Displays updated pH and temperature every second.
Just the essentials
Basic view provides measurement information in a clean, straightforward manner
All information on display
Table view is able to display measurement, time and date, annotations, and alarm status in a continuously updated table.
Fluid, dynamic graphing
Graph view provides measurement information linearly. Graph axes may be expanded using pinch-to-zoom technology for enhanced viewing
There are four ways to save and share data: All data since last auto-save, Annotations only, All data within a timed interval, and Annotations within a timed interval.
Share data via email in PDF or CSV format.
Saved data points may be annotated with measurement specific information.
Data is automatically saved every hour
GLP (Good Laboratory Practice)
Displays date and time of current calibration along with probe offset and average slope. For tablet displays, basic GLP can be also displayed in table and graph views.
Displays date and time of current calibration, probe offset, and average slope along with calibrated buffers, mV values, temperature and slopes between each buffer. For tablet displays, full GLP can be also displayed in table and graph views.
Clear and Concise Calibration Screens
The Hanna Lab App allows for calibration of up to five points. The buffer value is automatically detected and temperature corrected to 25.0°C during calibration.
Alerts users when HALO2 needs calibration.
Readings that exceed user-defined alarm thresholds are highlighted in yellow on the measurement screen, graph, and table. Readings that exceed the probe specifications are highlighted in red.
Tap the gear icon in the top right corner of the measurement screen to access the Settings menu.
Help and Tutorials:
The Hanna Lab App also features demo probe mode, general app information, general HALO information, pH tutorial, maintenance tutorial, and contact information.
