The Brix concentration, Refractive index or other parameters are always needed in lab or our life. The traditional optical refractometer is very popular used to measure these parameters. Compared with traditional optical refractometer, 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. The result will be showed in the display! With smart and beautiful shape, our Pocket digital refractoemeter will be a good instrument in your work!
