Refractometers

A refractometer measures the extent to which light is bent (i.e. refracted) when it moves from air into a sample and is typically used to determine the index of refraction (aka refractive index or n) of a liquid sample. Read more...

The measuring range of the successful half Brix OPTi which was launched in 2011 is extended by OPTi+ hand held refractometers.
Hand held refractometers are used for quick and convenient measurement of concentration in several semi-solid and liquid samples.
Digital Refractometer with built-in thermostat. 5 place digital refractometer for measurement of refractive index, BRIX, HFCS or concentration of aqueous solutions.
A number of leading companies consider the RFM300+ series refractometers as the ultimate instrument to be installed in challenging factory environments and also as a primary quality control tool.
The AR2008 Digital Abbe Refractometer features electronic data evaluation. The refractive index or Brix value can be read from an LCD display, together with the temperature. Automatic temperature compensation can be optionally activated. The AR2008 has a thermostat connector for prisms. Measurement values with the date and time of measurement can be transferred directly to a PC or printer via a serial interface. A 589nm integrated light source for the prism is present. The AR2008 is highly robust. Delivery includes a glass calibration plate, contact fluid and a screwdriver.
More stringent requirements of quality control and, in some cases, changing legislation, mean that greater accuracy is being demanded of refractometers. The Abbe 60 Direct Reading models, available in two measuring ranges, have been designed to meet these requirements.
Refractometers are important for veterinary and human use. The duo scale OPTi-Sport plays an important role in determining hydration levels of athletes and also in controlling the content of sugar in sports drink before consuming.
The Abbemat Heavy Duty Line refractometers from Anton Paar are specifically developed for unique applications and can be used for calculating the refractive index in challenging environments.
The Pro-Juice refractometer has been specifically developed to focus on the practical handling of the sample prior to high accuracy measurement in order to achieve a measurement accuracy of 0.01 °Brix for sucrose solutions.
901-110 Digital Refractometer is designed with state of the art electronics and precision optics combined to deliver optimum accuracy, speed and simplicity in determining refraction of liquids.
The OPTi digital hand-held refractometers are manufactured in UK as a highly reliable premium quality instrument suitable for arduous environments to be suitable for a large number of applications.
