Abbe refractometers have a larger range and are more acurate than the hand-held and digital models. An Abbe refractometer can determine many substances and concentrations. The use of a cold light source with glass fibre such as the LE.5209 is recommended. Equipped with scales for sugar concentrations and refraction indices and delivered in transport case with thermometer 0-50 °C, a calibration plate and adjustment tooling

Abbe refractometers have a larger measuring range and are more precise. They are suitable for measuring numerous substances and measuring concentrations
