1. Practical Refractometer: it is used to test the concentration and refractive index of sugar-containing solutions in fast and effective way. 2. LCD Digital Display: using LCD large screen display to simultaneously display temperature, sugar content, and refractive index, 1.5-inch display screen with backlight for clearly display. 3. Precision Optical Instrument: adopts high quality optical refractive sensor for quickly measuring in seconds, with high accuracy of ±0.2% Brix and resolution of 0.1%. 4. Dust-proof Protective Cover Design: well protected the optical prism, easy to clean, suitable for measuring various solutions. 5. Automatic Temperature Compensation(ATC)Function: for immediate and accurate calibration reading, not affected by the environment, reducing measurement errors caused by different temperatures. Lightweight and portable ATC sugar meter refractometer that is suitable for sugar content measurement of products with high sugar content such as liquid sugar, the production of fruit juices, refreshing drinks and carbonated drinks, and the process from planting to sales of fruits, for degree classification. Wide Applications: it can be used in sugar, beverage and other industrial sectors, as well as in agricultural production and scientific research for sugar content measurement of products with high sugar content.
