Description
Analogue refractometer KERN ORA 1UA is a universal, maintenance-free handheld instrument for refractive index measurement in laboratory and industrial settings. The handy, robust design enables straightforward, efficient long-term everyday use. Specially developed, exactly calculated and verified scales feature very thin, clear lines for reliable reading. The optical system and prism cover use materials chosen to support low-tolerance measurement, while the eyepiece provides simple, smooth adjustment to different eyesight strengths. Automatic temperature compensation (ATC) allows accurate results across ambient temperatures from 10 °C to 30 °C. This Kern ORA-U series model is especially suitable for the measurement and determination of urea. Delivery includes a storage box, calibration solution, pipette, screwdriver and cleaning cloth; further accessories are available optionally. The principal application area is the chemical industry, where dependable urea assessment supports process control and quality work. Compact form and maintenance-free operation make the instrument practical for routine laboratory and production environments requiring clear scale readability and stable optical performance.

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