1. 0 32% Range: The Brix meter is used to measure the sugar content in fruit juices, fruits, and beverages within the 0 32% range, to monitor the ripeness of grown fruits and vegetables, or for laboratory research. 2. Easy Measurement: After calibration, place 2 to 3 drops of the solution on the prism of the Brix meter and point it toward the light. Through the eyepiece, you obtain accurate results, making the testing process simple. 3. ATC Function: The Brix refractometer features an Automatic Temperature Compensation (ATC) function, which automatically adjusts for ambient temperature changes and eliminates deviations caused by temperature fluctuations. The optical lens with a refractive index and infinitely adjustable eyepiece ensures a clear view of the scale. 4. Handheld: The sugar refractometer is constructed from aluminum alloy, ABS, and rubber, making it sturdy, rust proof, wear resistant, and corrosion resistant.
