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. )

This refractometer is designed for measuring the suger content and specific gravity of liquids. A Brix Refractometer that includes a specific gravity scale. You won’t have to do conversions between Brix and gravity when doing measuring, you’ll get the two index in one time. Best of all, it only requires a few drops of liquid for an accurate reading. No need to lose a whole hydrometer test jar of beer or wine in the process.
