Anton Paar SmartRef Digital Refractometer

The SmartRef from Anton Paar is a digital measuring instrument designed for demanding brewers, winemakers, and aquarists. This portable refractometer uses a high‑performance optical sensor to instantly convert the refractive index into usable data directly on your smartphone via Bluetooth. In brewing, it becomes an essential tool by indicating the extract content of the wort expressed in °Plato, allowing precise monitoring of sugar extraction during mashing and boiling.
