Fast and Accurate: Lifancy digital Brix refractometer requires only 2 drops of sample to display results within 2 seconds. Measurement range 0-55% Measurement accuracy 0.2% /1% Automatic Temperature Compensation: The refractive index is affected by temperature, so we have set up the Automatic Temperature Compensation (ATC) function (10-40C) to accurately read BRIX at various temperatures. Clamshell Design: The upgraded Brix meter adds a shading protection cover to protect the test prism from external factors, which is faster, more accurate and clearer than traditional handheld refractometers. Screen Backlight: Our digital BRIX tester features a large backlit screen for easy viewing of readings in low light conditions. 3 IN 1: The unit has functions such as refractive index, BRIX and temperature, so it can be used in various applications such as fruits, beverages, , beer, honey, various sauces and laboratory experiments.
