Portable Refractometers

• Accurate, professional-quality instruments you can use everywhere.

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 eye piece and bright, clearly defined scale make it easy to read measurements. Available in a range of sugar, salt and clinical models; all come ready for immediate use with calibration tools, solutions, transfer pipettes, protective case and complete instructions. Nos. 30387 and 30391 come with automatic temperature compensation which makes manual temperature corrections unnecessary.
