1. ATC FUNCTION: The Brix refractometer features an ATC function that automatically compensates for ambient temperature changes, eliminating deviations caused by temperature fluctuations. The highrefractiveindex optical lens and infinitely adjustable eyepiece ensure a clear view of the scale. 2. EASY MEASUREMENT: After calibration, simply place 2–3 drops of the solution on the prism of the Brix meter and point it toward a light source. Accurate results can be read through the eyepiece, making the testing process effortless. 3. STORAGE CASE: The portable sugar refractometer includes a storage case, a mini screwdriver for calibration, a pipette, and a cleaning cloth (color may vary). It is easy to clean and store after use. 4. 0–32% RANGE: The Brix meter measures sugar content in fruit juices, fruits, and beverages within a 0–32% range, helping monitor the ripeness of grown fruits and vegetables or assisting in laboratory studies.
