[Practical Refractometer]: Used to quickly and effectively test the concentration and refractive index of sugary solutions. [LCD Digital Display]: Adopts a large LCD screen to display temperature, sugar content and refractive index at the same time, and the 1.5-inch display screen with backlight has a clear display. It has a wide range of uses and can be used in industrial sectors such as sugar making and beverages, as well as in agricultural production and scientific research to measure the sugar content of products with high sugar content. [Precision Optical Instrument]: Adopts high-quality optical refraction sensors, which can quickly measure in a few seconds, with an accuracy of up to ±0.2% and a resolution of 0.1%. [Dust-proof protective cover design]: It protects the optical prism well, is easy to clean, and is suitable for measuring various solutions. [Automatic Temperature Compensation (ATC) Function]: Readings can be calibrated accurately immediately, unaffected by the environment, and measurement errors caused by different temperatures can be reduced.
