Float Pro – The New Standard in Digital Hydrometers
We are proud to introduce the Float Pro – our completely redesigned digital hydrometer and thermometer that takes fermentation monitoring to the next level.
We didn’t just improve on what was already there; we reimagined the concept of a hydrometer from the ground up.
The result? A robust, smart, and accurate instrument that gives every brewer professional insights.
Smarter, More Accurate, Better Built
The Float Pro elevates your brewing process — from the preparation of your brew to the last molecule of CO₂.
Quick, easy setup – Ready to measure in just minutes.
No calibration needed – Use straight out of the box.
Real-time fermentation insight – Track SG and temperature continuously without opening your fermenter or taking samples.
Multicolor LED indicator – See the status of the Float Pro at a glance.
Wireless and USB-C charging – Choose whichever is most convenient.
Automatic data sync – All your measurement data securely stored and organized in your free My Brewbrain account.
Technical Highlights – Under the Hood of the Float Pro
Completely New Internals
The Float Pro has been redesigned from scratch: New sensors, electronics, and firmware deliver higher accuracy, stability, and energy efficiency.
Precise Sensor Technology
Advanced accelerometer detects subtle density changes.
Enhanced temperature sensor with improved accuracy for reliable readings.
Smart Energy Management
Thanks to more efficient hardware and firmware, the Float Pro lasts longer on a single charge. Each Float Pro allows for USB-C or wireless charging, whichever is more convenient for you.
Multicolor LED Status Indicator
The built-in LED shows the Float Pro’s status at a glance — battery level, Wi-Fi connection quality and connection to the My Brewbrain platform. You can change the color of the LED for easy recognition.
Pressure-Resistant Design
The Float Pro has been rigorously tested for pressure resistance and operates flawlessly up to 2 bar — ideal for brewers fermenting or lagering under pressure.
Optimized Buoyancy
Simulations and real-world tests have refined the Float Pro’s buoyancy, ensuring the most stable readings in all type fermenters.
Durable Dutch-Made Housing
The casing is injection-molded in the Netherlands from food-safe materials, designed with the perfect geometry for beer brewing and the right to repair in mind.
It also withstands all common brewing cleaning and sanitizing agents, making maintenance quick, safe and worry-free.
Improved Connectivity & Integrations
Better antenna placement ensures stronger Wi-Fi coverage and a stable connection, even in metal or pressure-proof fermenters.
Through the My Brewbrain platform, you can easily integrate with, amongst others, Brewfather and Grainfather. Automatically syncing all your fermentation data with your brewing software of choice.
Designed for Today’s and Tomorrow’s Brewer
The Float Pro is pressure-resistant, easy to clean with standard brewing sanitizers, and ready to use immediately.
Whether you brew in stainless steel conicals, plastic buckets, or pressurized vessels — the Float Pro fits seamlessly into any setup.
“We didn’t want a version 2 of the Float. We wanted something that truly makes the brewing process smarter — something we as brewers would actually want to use ourselves.”
