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. Affordable than a digital brix refractometer and more accurate than hydrometer MEASURING SUGAR CONTENT: Brix meter scale 58-92 % 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 daily life juice drinking AUTOMATIC TEMPERATURE COMPENSATION: 58-92 % 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 WHAT YOU GET: Handheld brix refractometer, mini screw driver for calibration, pipette, cleaning cloth, plastic box and plastic box 58-92 % Brix Refractometer can measurement sugar content in fruit, food, juice, tea and beverage as well as measurement of sugary liquids such as brandy, beer, fruit juice. With this ATC brix refractometer you can easily make juice, beverage and tea at home, easily to control self-drinks sugar content This brix hydrometer also suit for laboratory and educational instrument. Features: This portable brix hydrometer refractometer is based on the principle that the reflective indices of liquids change when the concentration changes. Refractometer is super easy and quick to measure solution concentration, no battery required. Easier and more accurate than a traditional hydrometer, more affordable than a digital meter. Brix refractometer main body is made of aluminum alloy, features high quality optics with sooth focusing system, study and durable for long time using. refractometer with ATC function, can automatic temperature compensation according to changes in ambient temperature, easy and fast to get the accurate readings ATC (Automatic Temperature Compensation) Compensation range: 10 C ~ 30 C (50 F ~ 86 F) Specifications: Reference Temperature: 20 C Measuring Range: Brix 58-92 % Resolution: +/-0.2% Package included: 1 Handheld Brix Refractometer 1 Mini screw driver 1 Pipette 1 Cleaning cloth 1 Instruction manual 1 Plastic box
