EASY & QUICK MEASURING: After calibration, put 2-3 drops on prism, easier and fast to get the accurate readings. Brix refractometer is much easier than using a hydrometer and needs less sample solution. MEASURING SUGAR CONTENT: Brix meter scale 0-32% designed for measuring sugar content in fruit, juice and beverage, monitoring ripeness of growing fruits and vegetables as well as for lab research. Easy for you to control the sugar intake in your dailylife juice drinking. AUTOMATIC TEMPERATURE COMPENSATION: 0-32% Brix meter with ATC, which can automatically compensated temp when ambient temperature changes, quick and easier to get the readings. DURABLE & PORTABLE: Sugar refractometer is made of aluminum and ABS rubber, sturdy design, anti-rust and resistant to abrasion and corrosion. Optical lens with high refractive index provide accurate measurement.
