Refractometers

We supply digital and optical refractometers for all applications, including salinity, Brix, specific gravity, car batteries, sucose, alcohol, serum protein, urine etc. We have the refractometer models presented and displayed on our Ecotao shop, https://www.ecotao-store.co.za/product-category/laboratory/refractometers/

See also a generalized overview of DIGITAL REFRACTOMETERS and optical refractometers.

The Brix scale refractometers cover a wide range of applications from cutting fluids (0-10% brix and 0-32% brix) to fruit juice and honey.

Optical or Handheld Refractometer

An optical handheld refractometer is an analog instrument that needs a bright natural light source to measure a liquid’s refractive index. Handheld refractometers are compact and easy to use, but less precise than the digital refractometers. Handheld refractometers are ideal for laboratory or industrial and production plant measurements. A drop the sample liquid is placed to fully cover the top of the glass sensor prism. Typical uses are for calculating the Brix value of fruit juices, crops, soft drinks, sauces, soups, water-soluble cutting oils, washing liquids, industrial liquids, and coolants. The refractometers are supplied as a variety of models calibrated to a specific measurement. For example a salinity refractometer measures the water salt content and cannot be used for fruit juices.

Digital Refractometer

Digital refractometers have a higher resolution than optical refractometers, generally producing a far more accurate reading. A good optical or digital refractometer has automatic temperature compensation so adjusting for the effect of temperature on the refractive index. Generally a digital refractometer has a wider scale and far higher resolution and precision.

Other refractometers

Refractometers are used in a wide range of applications such as  brix, salt (salinity), honey, antifreeze (ethylene and propylene glycol), wine, fruit drinks, sugar content (e.g. before cutting sugar cane), clinical, oil, cutting fluids, brake fluid, battery water, ABS and more. The clinical units measure serum protein (SP), SG (specific gravity) and RI (refractive index). Optical and digital models are available. We also supply specialist gem refractometers.

Within the brix range are numerous scales from 5% to 92%, allowing better precision in a preferred brix range.
