Digital refractometer 403
DR403Alcohol VOL
A refractometer is an instrument to
measure the concentration of aqueous solution by measuring it’s
refractive index. All water based solution can make light
bend.thebending of light increases at a rate proportional to the
increasing solution concentration. Digital refractometer is a precise
optical instrument.it’s characterized by small volume,light
weight,graceful in shape and easy to operate.there fore it can be used
by all sides.

Digital brix refractometer is designed to measure the concentration of soluble solids(almost sugar) in aqueous solutions of sugar content of solution such as fruit juice,syrup,puree,ade,coffee drinks,cocoa drinks,soft drinks,water-soluble cutting oil,water-soluble washing solution,etc. as well as measuring refractive index of solution.the unit features automatic temperature compensation(ATC)which make temperature corrections unnecessary between 0 to 40 ℃(32~104℉). It utilizes the standardized brix scale which is accurate and easy to read. The digital display is quick and easy to read brix readings.
