Our Digital Handheld Refractometer LHRF-B13 is designed to precisely measure refractive index, Brix values, and sugar content in fruits, vegetables, juices, beverages, honey, and food processing, ensuring accuracy in laboratory and industrial applications.
Labtron Portable Refractometer comes with a wide range of models to measure the boiling and freezing points, brix, TDS, density, specific gravity, refractive index, and concentration, of fruits, beverages, oils, and organic solvents. They obtain precise measurements with automatic and zero calibration using distilled or tap water. Some models are equipped with standardized brix scales for easy reading and accuracy. To conserve battery life, they automatically power down after one minute of inactivity. Our microprocessor-controlled Portable Refractometer provides easy-to-read results on an LCD screen.
