A PROJECT ?
While the traditional glass hydrometer and manual optical refractometer remain essential tools for beginners, there comes a point when a passionate brewer — or a professional seeking consistency — demands absolute precision and flawless readability.
This is where Anton Paar enters the stage.
As the undisputed global leader in density and concentration measurement in the professional brewing industry, this Austrian manufacturer brings its laboratory‑grade expertise within reach of homebrewers and craft brewers through a revolutionary range of connected digital instruments.
Why choose Anton Paar’s digital technology?
The strength of the Anton Paar range lies in the complete elimination of human error. No more squinting at blurry graduation lines on a tilted hydrometer, or approximating readings on a poorly lit refractometer prism. Everything is measured electronically, automatically temperature‑corrected, and instantly sent to your smartphone via a dedicated app (iOS and Android) that tracks your fermentations through clear, intuitive graphs.
The EasyDens Smart Densimeter: Surgical precision
The EasyDens Connected Densimeter is the ultimate tool for monitoring your fermentations. Based on the patented oscillating U‑tube principle — the same rigorous technology used in major industrial laboratories — it delivers unmatched measurement accuracy.
- Maximum efficiency: It requires only 2 ml of liquid for each measurement. Say goodbye to wasting precious beer volumes in large test cylinders!
- Integrated alcohol correction: Thanks to the mobile app and its powerful algorithms, the EasyDens automatically calculates your true density, alcohol content (ABV), and attenuation, even during active fermentation. To learn more about how it works, feel free to check out our dedicated EasyDens blog article.
The SmartRef Digital Refractometer: Absolute speed
For brew day, the SmartRef Digital Refractometer combines the speed of optical measurement with the rigor of digital accuracy. Ideal for measuring hot wort during mashing, lautering or boiling, it features a high‑resistance intelligent prism.
- Instant reading: Simply place a few drops on the stainless‑steel sensor, and the SmartRef immediately displays the exact value in Brix, Specific Gravity (SG), or Plato on your screen.
- Advanced thermal compensation: Its ultra‑fast temperature sensor compensates for variations in a fraction of a second, ensuring reliable readings even from wort taken directly from the boil kettle.
Rolling Beers Team Tips
Investing in laboratory‑grade equipment like the Anton Paar range requires a strict cleaning protocol to preserve sensor sensitivity. Before each measurement session, make it a habit to calibrate your device with distilled water. After use, thoroughly rinse the EasyDens measuring cell or the SmartRef prism with warm water, then apply a few drops of 70% isopropyl alcohol to remove any sugar or hop‑oil residues that could dry and distort future readings. A clean instrument is the key to years of uncompromised precision!
