ABSTRACT:
The invention relates to a portable refractometer comprising a depression (7) for samples, located on an insertion tip (11) in such a way that once the insertion tip (11) has penetrated a liquid or a fruit, a sufficient quantity of the sample liquid remains in the depression (7) for samples, thus wetting a measuring surface (4) that is delimited in said depression by a transparent body. The refractive index of the wetting liquid can be determined by measuring the intensity of an optical beam that is reflected by the measuring surface (4).
