The HALO® Wireless pH Meter for Flat Surfaces incorporates Bluetooth® Smart technology with an application-specific design. There are several features that make it ideal for measuring the pH of agar plates, skin, or leather, by providing a flat glass tip that allows a larger surface area than a typical pH electrode..
Flat Glass Tip
A flat tip optimizes surface contact for measurement on flat surfaces such as agar plates, skin, leather, paper, and samples that cannot easily be penetrated
Low Temperature Glass Formulation
Low Temperature (LT) glass Low temperature glass for fast stabilization and more accurate results at lower temperatures. This is beneficial since many food products are stored at low temperatures.
Open Junction Reference
The open junction design uses a solid gel interface between the sample and internal reference cell. This interface prevents silver from exiting the junction, but also makes it impermeable to clogging, resulting in a fast response and stable readings. Due to this design, the HALO can be used for smaller sample sizes as there is no junction to submerge.
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
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.
