Portable Refractometers Go With You Everywhere
Accurate, professional-quality Portable Refractometers measure dissolved substances accurately in the lab or in the field. Since no battery or other power source is needed, they're totally portable—you get precise, reliable readings with ambient light! Simply place a drop or two of your sample on the prism and read the results immediately.
All models feature a rubber-coated hand grip and insulated construction to prevent inaccuracy caused by the body heat of the user. The covered eyepiece and bright, clearly defined scale make it easy to read measurements.
