The Abbe refractometer measures refractive indexes nD,
solid contents in % and mean dispersion values nF-nC
of tranparent and translucent liquids or solids. When
connected to a thermostat the instrument can measure
the refractive indexes from 0–70 °C.
The refractive indexes and the dispersion values belong
to the important optical data of substance with which
the concentration, purity and optical condition can be
tested.
The Abbe refractometer has a wide field of application
eg. in the petro-chemistry, oil and lubrication industries
and in the pharmaceutical, chemical, food and
It is suitable for use in the following analyses:
• Determination of concentration
• Determination of mixing ration
• Purity control
• Manufacturing control of products
The Abbe refractometer is delivered in styrofoam pack-
ing material. Remove the instrument and the attache-
ments from the packing. Mount the illumination and
digital thermometer as follows:
Important!
► First screw in the thermometer.
