Description
Analogue refractometer KERN ORA 1GG is a universal, maintenance-free handheld instrument for refractive index measurement in laboratory and industrial practice, with a scale layout dedicated to jewelry determination. The compact, robust design supports simple, efficient and durable everyday handling. Scales are specially developed, precisely calculated and verified, and are characterised by very fine, clear lines. The optical system and prism cover use selected materials that enable low-tolerance readings. An ocular with straightforward, smooth adjustment adapts the view to different visual acuities. Delivered ready for use from manufacturer Kern, the set includes a storage box, calibration block, contact liquid, pipette, screwdriver and cleaning cloth; this model additionally comes with a quality leather case. Optional accessories extend the system as needed. Principal application areas are jewelers, the jewelry industry and training environments where reliable refractive index assessment of gemstones and related materials is required on a routine basis.
This article is part of Refractometers & polarimeters, in Spectroscopy & photometry.

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