Honey Refractometer for Honey Moisture, Brix and Balsam, 3 in 1 Use, Honey Moisture Tester 58-90% Brix with ATC, Great for Honey, Maple Syrup; Molasses, food for bees The refractometer series is based on the principle that the refractive index of a liquid changes with concentration. Portable, simple, fast and battery-free, it is easier and more accurate than traditional water meters and more affordable than digital meters. It's the perfect tool for adults or young adults, for home or professional use. It has high quality optics and smooth focusing. Its body is made of aluminum alloy. The built-in high refractive index optical lens is a precise optical system. The instrument is wear and corrosion resistant and can be used to measure general corrosive liquids. (But we do not recommend measuring these liquids for long periods of time. Residues should be removed immediately after measurement.) 3 in 1 Honey Refractometer This refractometer is a portable precision optical instrument which is a convenient tool for checking the quality of honey and other liquids at high in sugar such as maple syrup and molasses. Helps you understand the ideal time for harvesting honey or producing maple syrup. Its 3-in-1 ratio design lets you know three measurements at once: Honey Humidity/Brix/Balm. Measuring range: water content (moisture) 12-27%, Brix 58-90%, Be' (Baume) 38-43. Ranking : 0.5% water, 0.5% Brix, 0.25 Be' (Balm). DURABLE AND SAFE MATERIALS This honey refractometer is made of non-staining, non-corrosive and non-reactive chrome material to ensure the hygiene and safety of all users. Automatic Temperature Compensation Built-in automatic temperature compensation lets you get consistently accurate readings, you don't need to control the temperature of the liquid, just make sure it's at room temperature (between 0 and 30 degrees). The handheld compact refractometer comes complete with a dropper, screwdriver, user manual and cleaning cloth all contained in a compact hard case, item measures 8"x3"x2" and the item weighs only 8.6 oz. Very portable and convenient transportation. Is it complicated to use a refractometer? Easy to use. Using a refractometer is actually quite simple. Using a refractometer is done in two simple steps: Calibration and measurement. Calibration: Put a few drops of calibration solution on it and adjust the calibration screw with a screwdriver until the reading is appropriate. (The user manual documents the details of the correct calibration solution and reading index.) Measurement: Put a few drops of the solution you want to test on the prism and look through the eyepiece and you will get the reading.
