OleiniTec Nordic AB offers refractometers for every demanding Laboratory application for Measuring Refractive Index. We offer high quality refractometers for measuring refractive index, Brix, refractive index of solids from leading manufacturers Rudolph Research Analytical and Maselli.

Rudolph is a leading analytical laboratory instrument supplier that manufacture precision quality, benchtop instrumentation like Refractometers, Density meters, Polarimeters, Saccharimeters and AlcoTest-RI. Rudolph have served the Pharmaceutical, Chemical, Petroleum, Petro-Chemical, Food, Beverage, Flavour, fragrance, and Alcohol industries for more than 50 years and have more than 8000 instruments installed all over the world. All the instruments are designed to meet specific application requirements and are designed to exceed your requirements.

Main refractometer features:

  • Shallow refractometer sample well

– Refractometer measurement accuracy is only as reliable as the cleanliness of the sample well. Thus, hard to clean sample wells can lead to inaccuracies. Using higher quality optics Rudolph was able to design a sample well that is very shallow and smooth. The result is more accurate measurements due to significantly sample cross-contamination

  • Advanced sample temperature control

Rudolph’s sample well has an electronic heating and cooling system. This greatly improves results and is simple to use.  Some applications require highly controlled temperature. A temperature-controlled sample cover can be added to ensure even and accurate temperature stability. Thus, temperature-controlled samples from both the top and bottom allow for the most accurate measurement.

  • Durable Sapphire Prisms with Long-life Light sources. Low Life of instrument cost.
  • 3 Year Warranty
  • 20 Year Support Guarantee

Rudolph Research line of Automatic Refractometers



Maselli is a leading supplier of both inline refractometers and laboratory refractometers for measuring refractive index and brix, focusing on the beverage industry. The refractometers are accurate, robust, compact and  easy to use both in the laboratory and out at the line.


LP10 – Laboratory Package for Beverages


The LP series is a complete range of optical sensors for the beverage industry for measuring refractive index, brix, fresh brix, diet, CO2 and O2. The design is modular: the system can be composed of different analysis modules based on the needs and they are all handled by a single control panel. It is possible to upgrade the initial configuration with additional analysis modules at any time. Being used as bench top analyser, the LP10 includes a semi-automatic sampler for picking the beverage samples from all types of containers.


Beer analyzerThe UR24 digital refractometer is a stand-alone unit designed for simple installation in-line or in a tank. The analyzer provides a continuous measurement of concentration that can display the result in Brix, nD, or % concentration with high accuracy. The UR 24 also features a user programmable scale for specific applications.



The UR62 digital refractometer is a probe designed for simple installation in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with basic accuracy. The UR62 will signal to the process when concentration is outside of specifications or has reached its target end point by means…


The URX1 digital refractometer is designed specifically for hazardous areas up to Zone 0: the equipment certificate is ATEX II 1 G – EEx ia IIB T4. You may simply install the unit in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with high accuracy
