The HALO® Wireless Field pH Meter incorporates Bluetooth® Smart technology with an application-specific design. There are several features that make it ideal for taking pH measurements in the field.
PEI is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode. PEI is a high quality plastic that is chemically resistant to many aggressive chemicals.
HI12302 features a built-in temperature sensor for temperature measurement and compensation.
The spheric bulb is for general purpose use within laboratory environments and applications that measure aqueous solutions due to its large surface area.
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.
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.
Displays date and time of current calibration, offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.
The Hanna Lab App alerts you when HALO needs calibration or if a measurement threshold is exceeded.
Saved log files may be annotated with measurement-specific information. Data is easily shared via email in CSV or PDF format.
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.
