The 10 Best Refractometers
We spent 22 hours on research, videography, and editing, to review the top picks for this wiki. Aquarium owners, brewers and beekeepers, take your pick. These refractometers will help you measure the salinity and specific gravity of tank water, the specific gravity and sugar content of a brew before fermentation, or the amount of water in honey. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best refractometer on Amazon.
