KERN Digital Refractometer ORM 2UN

KERN ORM 2UN Digital Refractometer

The KERN Digital Refractometer ORM 2UN is a high-precision, digital handheld refractometer that has been specially developed for use in veterinary medicine and laboratory diagnostics. It provides fast and reliable, precise measurement results when analysing urine samples from dogs and cats, but is also suitable for determining the refractive index and Brix value in a wide variety of laboratory environments. The ORM 2UN sets standards in user-friendliness, robustness and measurement accuracy - in particular thanks to its digital display, automatic temperature compensation and IP65 protection class, which offers ideal protection against moisture and dust even in demanding practical or field use.

Thanks to its versatility, reliability and the ability to calculate the average value from up to 15 individual measurements, the ORM 2UN makes everyday work in veterinary laboratories and veterinary practices more efficient and safer compared to conventional optical refractometers.

Precision and functionality for veterinary practice use

The Kern & Sohn ORM 2UN is designed to meet the highest demands in the field of veterinary diagnostics and combines powerful measurement technology with a robust, user-oriented design. The device operates on the basis of total reflection, which ensures accurate determination of specific gravity (sgU), refractive index (nD) and Brix values. Automatic temperature compensation reliably eliminates deviations caused by ambient temperatures ranging from 0 °C to 40 °C - a clear advantage for precise analyses under changing conditions.

The digital display ensures that measured values can be read without subjective misinterpretation. The special precision prism made of lanthanum flint glass (ZLaF3) offers high resistance even to more aggressive samples and is particularly durable.

Its IP65 protection class guarantees maximum protection against dust and splash water - indispensable in busy laboratory or practice environments.

Specific examples of use in veterinary laboratory operations

• Monitoring kidney disease in dogs and cats: Determination of specific gravity to assess kidney function.
• Fast, reliable urine analysis: Routine measurements to monitor fluid and electrolyte balance.
• Long-term studies in research institutions: Analysis of changes in urine over time, especially for animal studies and clinical field research.
• Quality control in the laboratory: Testing of veterinary supplements and feed by means of Brix and refraction measurements.
• Measurement of sugar content in veterinary preparations: Suitable for Brix determinations in feed and supplement samples.
• Analysis of other aqueous or sweet solutions: Versatile use in laboratory diagnostics and food control thanks to the Brix scale.

  Typical substances examined include dog and cat urine and various laboratory solutions such as NaCl, glucose or fructose solutions.

  FAQs

  Cleaning the measuring prism

  Rinse the prism with distilled water or a neutral cleaning fluid after each measurement. Dry the surface carefully with a lint-free cloth to ensure a long service life and accurate measurement results. Measuring other liquids In addition to urine samples, Brix and refraction values can also be determined for aqueous and sugary solutions, making the device very versatile for use in laboratories and production.

  Calibration in case of temperature fluctuations

  Automatic temperature compensation covers fluctuations from 0 °C to 40 °C. Calibration with distilled water is recommended before the first measurement of the day or in case of significant temperature changes in the working environment.

  Comparison of multiple measurement runs

  The mean value function is available for comparative statements, which calculates an average from up to 15 individual measurements - ideal for variable samples or samples that need to be checked multiple times.

  Resistance to moisture and dust

  IP65 certification ensures that the device functions reliably even in dusty or humid conditions in the laboratory or everyday practice.

  Conclusion

  The ORM 2UN digital handheld refractometer from Kern & Sohn is a reliable diagnostic tool for veterinary laboratories and veterinary practices. Precision, robustness and innovative features such as temperature compensation and averaging function ensure high-quality results - both in routine analysis of urine samples and in research and quality control. CE and IP65 certifications stand for tested safety and durability. Thanks to its self-explanatory user interface and compact design, the device is ideal for demanding professional users in the veterinary field.
