Beschrijving
Analogue refractometer KERN ORA 1UB is a universal, maintenance-free handheld instrument intended for refractive index measurement in laboratories and industry. Its compact, robust build supports simple, efficient and lasting everyday operation. The scales are specially developed, precisely calculated and verified, and are characterised by very thin, clear lines that aid accurate reading without manual conversion steps. The optical system and prism cover are manufactured from materials that enable low-tolerance measuring, and every unit includes an eyepiece with straightforward, smooth adjustment for different visual acuities. This Kern ORA-U series model is particularly suited to the measurement and determination of urea. The scope of delivery comprises a storage box, calibration solution, pipette, screwdriver and cleaning cloth; additional accessories can be ordered separately. Primary application lies in the chemical industry, where reliable urea assessment is required for process and quality tasks. Maintenance-free design, clear scale presentation and durable handheld construction make the instrument a practical choice for routine analytical and production environments needing dependable refractive index-based urea readings.

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