Juice Refractometer 28–62% Brix ATC — High-Range Sugar Refractometer for Fruit & Must

This 28–62% Brix refractometer with Automatic Temperature Compensation (ATC) is a precision optical instrument purpose-built for measuring the high sugar concentrations found in fruit juice, grape must, concentrated syrups, and other sugar-rich liquids that fall outside the range of standard brewing refractometers. With a 0.2% Brix graduation and ATC correction active between 10–30°C, this metal-bodied refractometer delivers accurate, immediate sugar readings from just a few drops of liquid — no test tubes, no waiting, no product waste.

What makes this a specialist instrument rather than a general-purpose brewing refractometer is its elevated measurement range. A standard brewing refractometer typically reads 0–32% Brix — sufficient for wort, dilute fruit additions, and pre-boil gravity checks, but unable to measure the high sugar concentrations of undiluted grape must, fruit concentrates, honey, and fruit juices where Brix values regularly exceed 40–50%. This 28–62% Brix instrument fills that gap precisely — designed for the juice, winemaking, and fruit fermentation applications where sugar levels are high and accurate measurement at that range is critical for fermentation planning, dilution calculations, and quality control.

The metal construction gives this refractometer the rigidity and durability that plastic-bodied alternatives lack — the prism stays correctly aligned under regular handling, the scale remains readable, and the calibration holds stable across extended use in a working brewery or winery environment. Supplied complete with storage case, calibration screwdriver, pipette dropper, and instruction manual, everything needed for immediate, accurate use arrives in the box.

Usage

Best suited for: Grape must sugar measurement, fruit juice Brix testing, honey and syrup concentration, fruit concentrate dilution calculations, high-sugar winemaking and cider quality control

Not suitable for: Standard wort gravity measurement (use a 0–32% Brix brewing refractometer), post-fermentation alcohol estimation in beer or wine (use a hydrometer or vinometer)

Calibration: Use distilled water — correct reading at 0% Brix (note: distilled water falls outside the 28–62% measurement range; calibrate using the manufacturer's method with the included screwdriver).
