Refractometer

Browse refractometers for Brix, salinity, honey, wine, gemstone, and lab-style concentration checks. This collection includes handheld and digital refractometers for practical field, food, beverage, agriculture, aquarium, and inspection tasks. Compare measurement scale, range, resolution, ATC support, sample type, calibration method, and display format before choosing a model. For salinity-specific work, also review the Salinity Meters collection to match the instrument to saltwater or brine measurements. Use product pages to confirm units and calibration requirements.

Choose a Refractometer by Measurement Task

• Brix and sugar concentration: use a Brix scale for fruit, juice, beverages, and other sugar solutions. Compare the 0-35% Brix model, the 0-53% Brix model, and the 0-55% Brix model according to the expected sample range.
• Honey: choose a honey-specific scale when moisture, Brix, Baume, or refractive index is required. Compare the handheld honey Brix refractometer with the 4-in-1 digital honey refractometer.
• Brewing, wine, and ethanol: wort Brix or specific gravity and ethanol concentration are different measurement tasks. Use the beer and wort refractometer for brewing samples, the wine refractometer for its listed grape and wine scales, or an ethanol concentration tester when the required scale is % VOL.
• Salinity: match the range and units to seawater, aquarium, brine, food, or research work. Options include the aquarium and seawater meter, the 0-28% salinity refractometer, and the PAL-104 salinity refractometer.
• Specialized scales: use a dedicated instrument for measurements outside the categories above, such as the DEF/urea tester, the coffee TDS and Brix meter, or a gemstone refractive-index meter. These scales are not interchangeable.
