Digital Refractometers

For quick and accurate measurement of sugar, sodium chloride, specific gravity and freezing point.

A digital Refractometer is an instrument used to measure the refractive index of a liquid, and to convert this information in specific units such as sugar content (% Brix), Specific Gravity, Sodium Chloride, Freezing Point.

Digital Refractometer for Analysis of Sugar in food We offer four sugar refractometers to meet the requirements of the food industry. They are ideal for the analysis of fruits, energy drinks, soy milk, juices, jam, honey, maple syrup etc.

Digital Refractometer for Sugar in Wine These refractometers are rugged, lightweight and waterproof for measurements in the lab or field. Each instrument offers a different way to measure the density of grape must and other sugar based liquids.

Digital Refractometer for Seawater Analysis For the determination of salinity of natural or artificial seawater in 3 popular measurement units: Practical Salinity Units (PSU), salinity in part per thousand (ppt) or specific gravity (S.G. (20/20)).

Digital Refractometer for Sodium Chloride in Food Ideal for the analysis of salad dressing, cheeses, condiments, pickles, canned food, milk, juices, energy drinks, soups etc.

Digital Refractometer for Ethylene and Propylene Glycol Used to determine the percent volume and freezing point of ethylene glycol and propylene glycol based solutions.

IP65 water protection, single point calibration with distilled or deionized water.

Light from an LED passes through a prism in contact with the sample (a few drops of the sample are placed in the well).

An image sensor determines the critical angle at which the light is no longer refracted through the sample. Specialized algorithms then apply temperature compensation to the measurement and convert the refractive index to the specified parameter.

  • Accurate readings in 1.5 seconds
  • Simple calibration
  • Water protection
