A handheld digital refractometer that reads sugar concentration on a 0-55% Brix scale in about three seconds, useful for checking juices, syrups, sauces and similar liquid samples. Its dual display shows Brix and sample temperature together, with automatic temperature compensation and a one-touch zero calibration to keep readings consistent between samples. The sapphire measuring prism resists scratching and corrosion, and the IP54-rated housing plus rechargeable battery make it practical for field or production-line use.
