Description
Analogue refractometer KERN ORA 1WB is a universal, maintenance-free handheld refractometer for refractive index work in laboratories and industry. Belonging to the ORA-W series, its handy, robust construction supports straightforward, efficient and durable daily use. Several selectable scales eliminate manual conversion effort and reduce application errors; the scales are specially designed, exactly calculated and checked, and feature very thin, clear lines. Automatic temperature compensation (ATC) enables precise measurements at varying ambient temperatures between 10 °C and 30 °C. The optical system and prism cover are manufactured from specialised materials that allow low-tolerance measuring, while the eyepiece offers simple, smooth adjustment for different eyesight. Delivery includes a storage box, calibration solution, pipette, screwdriver and cleaning cloth. This model from manufacturer Kern is especially suitable for measuring sugar content in fruit to estimate the alcohol fraction that can be expected, and for determining the ripeness of fruit such as grapes via fruit sugar. Main application areas are agriculture (wine and fruit growing), wine production, and must and alcohol manufacture. Optional accessories are available separately.
This article is part of Refractometers & polarimeters, in Spectroscopy & photometry.

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