The Sugar/Brix Refractometer comes with an instruction manual and additional materials needed for its use such as: B. distilled water, a soft cloth, an eyedropper and a small screwdriver. My high school daughter used it for a science fair project. My only complaint is that the gauges are small and difficult to read.
