Description
Handheld refractometer ORA 3WA (with ATC) is an analog instrument for refractive index determination, combining a Brix scale of 0–32 % Brix with an Oechsle scale of 30–140 °Oe. Automatic temperature compensation (ATC) supports reliable interpretation when temperature varies during physical-property testing. Dual-scale presentation allows Brix and Oechsle readings from the same handheld optical unit without external power. Supplied as 1 pc(s) and weighing 0,300 kg, this ORA series model from manufacturer KERN is intended for determination of physical properties and refractive-index workflows that require both scales. Analog construction provides direct visual scale access suited to laboratory and portable use. It fits equipment selections for refractive-index determination where an ATC-enabled handheld refractometer covering 0–32 % Brix and 30–140 °Oe is specified. Compact handling facilitates routine sample evaluation in professional settings. The ORA 3WA delivers a practical dual-scale analog solution when Brix and Oechsle ranges with automatic temperature compensation are needed together.
This article belongs on Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about Handheld refracto. ORA 3WA (with ATC), analog, 0-32 % Brix, 30-140 °Oe
What is this article?
Handheld refracto. ORA 3WA (with ATC), analog, 0-32 % Brix, 30-140 °Oe 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.
