Easily measure pH in mash, wort, and finished beer with the FC2142 Wireless Beer pH Meter. This HALO is designed for home and craft beer makers.
The built-in electrode features a titanium body, flat glass tip, and renewable cloth junction making it ideal for measuring the pH of mash or wort during the beer making process. All readings are transmitted directly to your Apple or Android device or the edge®blu.

Easily connect to the Hanna Lab App at the press of a button via Bluetooth wireless technology.

Visible from a distance, the LED “halo” light flashes to indicate the status of the probe.

The HALOs CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours.

The HALO® Wireless Beer pH Meter incorporates Bluetooth®Smart technology with an application-specific design to measure beer pH. Several features that make it ideal for measuring the pH in beer, mash, and wort.

The flat glass tip is easy to clean and prevents solids in mash and wort samples from collecting on the sensor for less maintenance. A built-in temperature sensor ensures fast, accurately compensated readings even during sudden temperature fluctuations.

The FC2142 features a cloth junction. When clogged, simply clear the junction by simply extracting 1/8″ of the junction from the electrode to expose a new portion, resulting in a renewed junction.

The titanium body offers increased durability that is ideal for rough environments.


Display of beer 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 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.
