FC2142 HALO® wireless glass/titanium pH/Temperature electrode for beer
About the FC2142 HALO® Wireless Beer pH electrode
- Easily connected 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 HALO's CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours
HALO® wireless beer pH electrode incorporates Bluetooth Smart technology. It is specifically designed for measuring the pH in beer, mash, and wort. Can also be used in cider making.
High Temperature Glass Formulation
The beer HALO® is used at elevated temperatures, such as in the wort or mash processes. It is suitable for samples from 0 to 80°C.
Titanium Body
The titanium body offers increased durability that is ideal for rough environments.
Cloth Junction
The FC2142 has a cloth junction. One advantage of the cloth junction is that it can be extracted from the probe exposing a fresh surface. This is very important since one of the major contributors to unstable measurements is a clogged junction likely to occur when measuring the pH of mash that has a high solids content. Having the ability to pull out a small portion (⅛”) of the junction will clear any clogging resulting in an increased life of the pH electrode.
