Description
Analogue refractometer KERN ORA 1SB is a universal, maintenance-free handheld instrument for refractive index measurement in laboratory and industrial environments. Its compact, robust construction supports simple, efficient daily use, while specially developed, precisely calculated scales with thin, clear lines remove the need for manual conversion and help avoid application errors. The optical system and prism cover are made from materials selected for low-tolerance readings, and the eyepiece offers smooth adjustment for different visual acuities. Supplied ready for work with a storage box, calibration solution, pipette, screwdriver and cleaning cloth, this Kern ORA-S series model is particularly suited to measuring and dosing the mass fraction of sodium chloride in water (salinity). Typical uses include sauce production and cooking, salt brines for bakery goods, preparation of pickling brines such as for brine cheese, meat marinades and seafood handling. Main application areas cover the food industry, restaurants and commercial kitchens, as well as marine and seawater aquaristics and fish breeding. Optional accessories are available separately.

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