Description
Analogue refractometer KERN ORA 1RE is a universal, maintenance-free handheld instrument for refractive index measurement in laboratories and industry, distinguished by an especially large measuring range thanks to a divided scale. Handy, robust construction allows simple, efficient and lasting use in daily workflows. The scales are specially developed, exactly calculated and checked, and present very thin, clear lines for confident reading. Optical system and prism cover are made from materials selected for low-tolerance measurement. Every unit includes an ocular with easy, smooth adjustment for different eyesight requirements. From manufacturer Kern the instrument is supplied with a storage box, calibration solution, pipette, screwdriver and cleaning cloth; further accessories are available optionally. The broad refractive-index span suits universal deployment wherever an extra-large measuring range is needed, supporting flexible laboratory, process and quality-control tasks without frequent instrument changes.
This article is part of Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about Analogue Refractometer KERN ORA 1RE
What is this article?
Analogue Refractometer KERN ORA 1RE 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?
