Hand-held refractometers are low-cost, portable instruments used for ‘on the spot’ determination of Refractive Index (RI) of liquids or the concentration of solutions. Offering a choice of scales, Eclipse refractometers can be used in a multitude of applications across many and varied industries.

A selection of scale types covering a wide range of common applications is available from within the Eclipse range as well as the unique Low Volume Brix Models that are favoured by zoologists and entomologists for having the capability of measuring samples of less than 1-microlitre such as nectar.
