Features 【Portable Brix Refractometer】This Brix refractometer is a professional instrument for measuring aqueous solutions such as sugar, honey, beer, juice, wine, beverages, etc. Widely used in the food industry to control sugar concentration in food and beverages. 【High Precision】: Accurate test results, 0~20% concentration measurement range, minimum scale is 0.2%. From planting the fruit to selling it, it can help determine the appropriate harvest period and aid in the classification of sweetness. 【Automatic temperature compensation】: Internal temperature compensation, ranging from 10℃ to 30℃. Easy to read with clear calibration. For ease of use, the handle holds comfortably and is non-slip. ATC (Automatic Temperature Compensation) provides accurate readings. 【How to use】: Open the lid, take a few drops of the solution to be measured, place it on the detection prism, close the lid and let the solution spread over the surface of the prism. Point the cover directly at the light source and turn the eyepiece adjustment handwheel so that the blue and white lines are clear. The proportional value of the dividing line is the concentration of the solution. 【Widely used】: Widely used in soybean milk concentration measurement, sugar manufacturing, food and beverage. It is also suitable for measuring the concentration of ketchup, plugs, honey, aqueous solutions, etc. Description: This brix refractometer is a professional instrument to measure the aqueous solutions such as sugar, beer and honey. Widely used for food industry to control the sugar concentrations in foods and beverages. Specifications: Measuring Range: 0~20% Minimum Scale: 0.2% Automatic Temperature Compensation: 10~30 ℃ Length: 17cm / 6.7inch Weight: approx. 219g Instruction: 1. Open the cover and carefully wipe the prism with a soft cloth. 2. Take a few drops of the solution to be measured, place on the detection prism, gently close the cover to avoid producing bubbles which will make the solution spread all over the prism surface. 3. Put the cover directly point to the light source or bright place, observe the field of view through the eyepiece. 4. Turn the eyepiece to adjust the hand wheel to make the blue and white line clear. The scale value of the dividing line is the concentration of the solution. Package Included: 1 x Refractometer 1 x Screwdriver 1 x Pipette 1 x Clean Cloth 1 x Box  Note: 1. Please use this instrument according to the instruction, be careful when using. Do not loose any connection part arbitrarily, prevent violently shock, impact and falling off. 2. Use clean and soft cloth to wipe the instrument, do not put into water directly to clean and avoid scratch of surface. 3. Storage the instrument at dry and non-corrosive place. 4. Storage the part well. 5. The adjustment range of eyepiece and hand wheel is within 2cm left or right. Do not adjust it over 2cm, otherwise it will be broken. Package List
