MA 871 Refractometer

The MA 871 digital refractometer for brix is an optical instrument that employs the measurement of refractive index to determine the % Brix of sugar in aqueous solutions. The method is both simple and quick. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds the instrument measures the refractive index of the sample and converts it to % Brix concentration units.

The MA 871 eliminates the uncertainity associated with mechanical refractometers and is easily portable for measurements in the field.
