KERN ORF 1RS Digital Refractometer
The KERN ORF 1RS Digital Refractometer is specially designed for professional applications in laboratories, industrial quality assurance and scientific environments. It impresses with its combination of portability, precision and versatility in analysing the refractive index of a wide variety of liquids. Thanks to its wide measuring range and robust construction, this digital refractometer is ideal for demanding tasks where reliability and ease of use are paramount. Compared to other laboratory refractometers, this model sets standards in terms of immediate measurement readiness and user comfort, particularly with features such as automatic temperature compensation and protection against environmental influences.
Precision and user-friendliness for laboratories and industry
The ORF 1RS offers you modern measurement technology in a compact space and has been developed in accordance with protection class IP65. This feature makes it resistant to dust and splash water - ideal for daily use under various laboratory conditions and in industrial production areas. Factory calibration allows immediate operation without additional adjustment. Thanks to the large, colour-intensive TFT display, operation is intuitive, measurement results are clearly visible at a glance, and additional parameters such as temperature are clearly displayed.
Flexible software integration allows you to select different scales depending on your requirements, making the device suitable for a wide range of analysis tasks. Automatic temperature compensation (ATC) guarantees consistent precision and minimises application errors that could arise from temperature fluctuations. This ensures consistently high accuracy in all measurements - a clear competitive advantage for laboratory managers or quality assurance officers.

Specific areas of application and typical uses
This versatile device can be used in numerous areas. The range of possible applications includes:
-
Food industry: Precise determination of the concentration of sugar solutions, juices or syrups, for example for quality control and product development.
-
Metalworking and mechanical engineering: Checking lubricants and cooling lubricants for optimal composition to ensure the efficiency of machine tools.
-
Chemical and pharmaceutical research: Checking the purity of laboratory reagents such as acetone, isopropanol and various solvents by precisely determining the refractive index.
-
Analytics in environmental technology: Rapid analysis of water samples or industrial wastewater with regard to their chemical composition.
-
Research and development: Precise control of formulations in the context of application studies and for the experimental evaluation of liquid substances.
Thanks to its wide measuring range, both aqueous and highly concentrated substances can be reliably analysed. Automatic temperature compensation is particularly helpful in changing environmental conditions - for example, when taking measurements in the field or between different laboratory rooms.
FAQs
How often should the device be recalibrated?
The device is delivered factory-calibrated for immediate use. With regular use and changing locations, periodic calibration checks are recommended to ensure maximum accuracy.
Is the refractometer suitable for aggressive chemicals?
The device is fundamentally robust in design. After use with aggressive substances, it should always be thoroughly cleaned with water and the optical surfaces carefully maintained to ensure long-term functionality.
What are the advantages of automatic temperature compensation (ATC)?
ATC automatically corrects the measurement results depending on temperature fluctuations in the sample material. This facilitates comparative analysis and increases reliability - especially when measuring multiple samples of different media.
For which sample volumes is the device suitable?
The refractometer requires only a minimum sample volume of 2 drops, which facilitates both quick individual measurements and analyses of small sample quantities.
