Help you know ideal time for honey harvest or maple syrup production. It's 3-in-1 scale design makes you know three indexes at one time:honey moisture/ brix/ baume. The measuring range: Water Content (Moisture) 12-27%, Brix 58-90%, Be' (Baume) 38-43. Division: 0.5% Water, 0.5% Brix, 0.25 Be'(Baume). -Durable Safe material This honey refractometer is constructed with non-staining, non-corrosive and non-reactive chromium material which make sure hygiene and safety for all users. -Portable Compact Package The refractometer comes with dropper, screwdriver, user manual and cleaning cloth, all included in a hard compact case, the item dimensions is 8"x3"x2", the item weight is lightweight. makes it very portable and easy to carry. Is it complex to use a refractometer? It's easy to use. It's actually very easy to use a refractometer. There are two brief steps to use a refractometer: calibration measuring. Calibration: Place a few drops of calibration solution on the prism and use the screwdriver to adjust the calibration screw untill the reading is proper. (The user manual record the details about the proper calibration solution and reading index.) Measuring:Place a few drops of solutions you want to test on the prism and look into the eye piece, you will get the reading. Package list: 1)1 x Refractometer 2) 1 x pipette 3)1x instruction manual 4)1x mini screw driver 5)1x cleaning cloth 5)1x Box (optional) The refractometer series are based on the principle that the refractive indices of liquids change when the concentration change. It's portable, easy, quick and no battery required, easier and more accurate than a traditional hydrymeters, more affordable than a digital meter. It's a perfect tool for adult or young, home or professional use. It features high-quality optics with smooth focusing. Its main body is made of aluminum alloy. The internal optical lens with high refractive index make up the precision optical system.The instrument is resistant to abrasion and corrosion, can be used to measure the general corrosive liquid. (But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. )
