Features 1. High Accuracy: Digital brix meter displays the brix of measured liquid clearly and accurately. Measuring range: 0-55%, accuracy: ±0.2%, resolution: 0.1%. This digital brix refractometer is compatible with home food sugar measurement, fruit purchasing and fruit sales. 2. Washable Design: The brix meter comes with a high definition display for fast readings. The stainless steel sample tank is easy to clean. Only 2-3 drops of sample are required to obtain accurate brix value, avoiding waste of whole pieces of fruit and food. It is compatible with beer brewing, wine making, coffee, mead brewing and laboratory use. 3. Automatic Temperature Compensation: The brix meter measures temperature, brix and refractive index. It is equipped with automatic temperature compensation (10-40℃) and a high-transmittance prism to ensure accurate readings under various environmental conditions. 4. Operation Steps: For initial use, perform zero calibration first, add 2-3 drops of sample, close the lid, press the 'MEAS' button and wait 5 seconds for the brix value to show on the screen. 5. Wide Application: This refractometer measures sugar concentration in fruits, beverages and vegetables. It is compatible with beverage quality management, food industrial sectors, agricultural production scientific research, as well as beer and wine manufacturing.
