I have wanted a digital hydrometer for some time now. It would primarily be useful to know the gravity of the beer to know when fermentation is complete, or if I wanted to leave a couple of points unfermented, depending on the style. I don’t like taking samples and using my standard hydrometer – it wastes the beer, it takes time, and it compromises the beer hygiene.
