Description
Analogue refractometer KERN ORA 2PB is a universal, maintenance-free handheld refractometer intended for refractive index measurement in laboratories and industry. The model is particularly suitable for determining specific urine gravity (density), serum protein content in urine and refractive index. Main application areas include hospitals, medical practices, medical training institutions, residential and nursing homes, and sports medicine such as doping control. Belonging to the ORA-P series from manufacturer Kern, it offers a handy, robust build for simple, efficient and durable everyday use. Multiple selectable scales remove manual conversion effort and help prevent application errors. Scales are specially developed, exactly calculated and verified, and feature very thin, clear lines. The optical system and prism cover are made from special materials that enable low-tolerance measuring, while the eyepiece provides simple, smooth adjustment to different visual acuities. Delivery includes a storage box, calibration solution, pipette, screwdriver and cleaning cloth; additional accessories are optionally available. With a net weight of 0,30 kg and gross weight of 0,35 kg, the instrument is practical for routine clinical and laboratory workflows.
This article is part of Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about Analogue Refractometer KERN ORA 2PB
What is this article?
Analogue Refractometer KERN ORA 2PB is the article on this page. Luminix Health distributes Kern for laboratory use. It sits in Refractometers & polarimeters, inside Spectroscopy & photometry, in Lab instruments.
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.
