Analogue refractometer KERN ORA 90BE is a universal, maintenance-free handheld instrument for refractive index measurement in laboratory and industrial environments. Handy, robust construction enables simple, efficient and durable everyday use. Specially developed, exactly calculated and verified scales feature very thin, clear lines, while the optical system and prism cover use materials chosen for low-tolerance measuring performance. An eyepiece with smooth dioptre adjustment accommodates different visual acuities. Thanks to a split scale, this model from manufacturer Kern offers an especially large measuring range for Brix determinations, making it ideal wherever an extra-wide Brix span is required. Typical use is universal Brix work across laboratory, production and quality-control settings that need broad coverage in a single handheld unit. The instrument is supplied with a storage box, calibration solution, pipette, screwdriver and cleaning cloth; additional accessories are available optionally. Pack size is 1 pc, with a net weight of 0,95 kg.
This article is part of Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about Analogue Refractometer KERN ORA 90BE
What is this article?
Analogue Refractometer KERN ORA 90BE is the article on this page. Luminix Health distributes KERN for laboratory use. It sits in Refractometers & polarimeters, inside Spectroscopy & photometry, in Instrumenten.
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.
