The OPTi refractometer may be used to control the dissolved solids or blend ratios of numerous products from fresh fruit to industrial chemicals.

Food applications include the measurement of sugar in grape must and other fresh fruit, processed food, sugar solutions and beverages.

The E-Line 80 is a dual scale Brix refractometer ideal for use in the food industry and other applications requiring concentration measurements over a wide measuring range up to 80° Brix (%weight sucrose).

E-Line 90 has 3 scales and the additional feature of achromatising prisms, making it ideal for use with samples that do not have the same dispersion characteristics as sugars.

The instruments feature an internal device that corrects for temperature (ATC) making the measurement fast and accurate and is ideal for use in beverage, confectionery, jam and other ‘sugar’ applications as well as for calculating concentration or blend ratios in industry such as antifreeze, coolants and quenchants.

The E-Line Gemological refractometer is a low cost, lightweight measuring instrument used by jewellers and traders of gemstones to measure polished stones.

Hand-held refractometers are portable instruments used for ‘on the spot’ determination of Refractive Index (RI) of liquids or the concentration of solutions.
