Sugar Refractometers

These portable refractometers work in ambient light without the need for battery or other power sources. They can be used in the lab, production line or field. Simply place a drop or two of sample on the prism and read the results immediately. Rubber-coated hand grip insulates the test solution from inaccuracies caused by body heat. Covered eyepiece and bright, clearly-defined scale make measurements easy to read.
