Float – where it all started

Our first wireless digital hydrometer. Still supported. Succeeded by Float Pro.

Float was our first wireless digital hydrometer; and proof that continuous fermentation monitoring belongs in every brewery. Thousands of homebrewers and craft brewers across Europe use Float to track gravity, temperature and fermentation activity in real time.

Everything we learned from Float we put into the new Float Pro. Same Wi-Fi connected simplicity, built further with pressure fermentation support, wireless charging and significantly better hardware.

Float is no long in production. We still fully support all Float owners. Float support.↗

Float Pro — built on what Float taught us

The core idea is the same: drop it in, track everything, don’t open your fermenter. Float Pro goes further where it counts.

Pressure fermentation ready Ferment under pressure without removing your hydrometer. Float Pro is rated to 2 bar, so it stays in during pressure fermentation and cold crashing.

Wireless charging No charging port in the cap means a better seal and easier cleaning. Qi-compatible, so any standard wireless charger works. USB-C is there as a backup.

Better hardware throughout USB-C, multi-color LED for at-a-glance status, improved accuracy and a 4-month battery life.
