HALO® Wireless pH Meter for Vials and Test Tubes

The HALO^® Wireless pH Meter for Vials and Test Tubes incorporates Bluetooth^® Smart technology with an application-specific design. There are several features that make it ideal for measuring the pH in vials, test tubes, and smaller vessel applications.

Tapered Glass Body

The narrow glass body is ideal for laboratory use, specifically with test tubes and vials. The glass is resistant to many harsh chemicals can be easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature-dependent. The faster the electrode reaches equilibrium, the steadier the reference potential.

Low-Temperature Glass Formulation

Low Temperature (LT) glass Low-temperature glass for fast stabilization and more accurate results at lower temperatures.

Spheric Glass Tip

The spheric bulb is for general purpose use within laboratory environments and applications that measure aqueous solutions due to its large surface area.

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 device.

Fluid, Dynamic Graphing

Measurements can be displayed alone on the display, with tabulated data, or as a graph. The graph can be panned and zoomed with pinch-to-zoom technology for enhanced viewing.

GLP (Good Laboratory Practice)

Displays date and time of current calibration, offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.

Calibration Reminder & Measurement Alarms

The Hanna Lab App alerts you when HALO needs calibration or if a measurement threshold is exceeded.

Log & Share Data

Works seamlessly with electronic lab notebooks (ELNs) to help you manage and share large quantities of pH experimental data. Saved log files may be annotated with measurement-specific information. Data is easily shared via email in CSV format.

Help & Tutorials

Demo mode helps you explore features of the Hanna Lab App. General app information, HALO information, pH tutorial, maintenance tutorial, and contact information are available in help.
