The Brix concentration,
Refractive index or other parameters are always
needed in lab or our life. Optical refractometer is
very popular used to measure these parameters. The
Digital refractometer with a digital readout and LCD
display will eliminate uncertainties and is more
convenient to use. Just about 0.3ml-0.5ml sample was
needed. With smart design, our new Pocket Type
digital refractometers will offer more accurate
testing. All our digital refractometers have the
following characters:
