Description
Analogue refractometer KERN ORA 20BA is a universal, maintenance-free handheld instrument for refractive index measurement in laboratory and industrial environments. As part of the ORA-B series, it combines a compact, robust build with reliable everyday handling. The specially developed, precisely calculated and verified scales show very fine, clear lines and support accurate Brix-related readings. Automatic temperature compensation (ATC) allows exact measurements at ambient temperatures from 10 °C to 30 °C. The optical system and prism cover are made from specialised materials for low-tolerance measuring; each unit now carries an engraved serial number, and the eyepiece adjusts easily to different visual strengths. The supply package includes a storage box, calibration solution, pipette, screwdriver and cleaning cloth. This model from manufacturer Kern is particularly suited to Brix value measurement for sugar-content determination in foods—especially fruit, vegetables, juice and sugar-containing beverages—and for monitoring industrial processes such as cooling lubricants and water-based mixtures. Key application fields include industrial process and quality control, the food and beverage sector, agricultural ripeness checks, and professional kitchens. Further accessories are optionally available.

Questions about Analogue Refractometer KERN ORA 20BA
What is this article?
Analogue Refractometer KERN ORA 20BA is the article on this page. Luminix Health distributes KERN for laboratory use. It sits in Refractometers & polarimeters, inside Spectroscopy & photometry, in Instruments de laboratoire.
A refractometer reads the refractive index of a liquid, often expressed as Brix for sugar. A polarimeter reads the rotation of polarised light. Both depend on temperature. A handheld refractometer and a thermostated benchtop instrument are different accuracies.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
Which category should I open next?
