Refractometers

GAOTek handheld auto refractometer designed to precisely assess refractive errors in diverse populations using advanced technologies such as ultrasonic ranging, cross line, flashing light, and sound.

GAOTek manual or digital abbe refractometer this device can measure the refractive index nD, the average dispersion nF-nC of transparent or translucent liquid or solid substance and mass fraction (Brix) of cane sugar solution; wide utilization in the fields as petroleum, oil, pharmaceutical, paint, food, chemical and sugar refining industries, as well as in geological prospecting enterprises, colleges, universities and scientific research institutions.

GAOTek digital abbe refractometer determine the refractive index nD average dispersion (nF-nC) of liquids or solids and the mass fraction of dry solids in aqueous sugar solutions, that is, Brix.
