Sper Scientific digital refractometers include Laboratory, Waterproof, and Pocket models. These
digital refractometers are fast and intuitive and can be used in labs, on production lines, in the field or
anywhere. Our digital refractometers measure items such as: honey, Brix or sugar content of a liquid,
salinity or salt content of a liquid, battery coolant, diesel exhaust and urine.
Portable refractometers work in ambient light with no battery or other power source necessary.
They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two
of a sample on the prism and read the results immediately. With reasonable care, their reliability,
precision, and optical performance will last forever.
