Description
Handheld refractometer ORA 3SA (with ATC) is an analog handheld instrument for refractive index determination using dual concentration scales. It measures 0–28 % NaCl and 0–32 % Brix, so sodium chloride content and Brix values can be assessed on the same compact device. Automatic temperature compensation (ATC) supports stable scale interpretation when ambient temperature is not perfectly constant. The unit comes as 1 pc and weighs 0,310 kg, fitting portable laboratory and process-side use. From manufacturer KERN, the ORA 3SA belongs to equipment for refractive index determination within physical-property measurement. Analog optical readout provides immediate visual access to the selected scale without electronic display hardware. Users can apply the NaCl range for saline solutions and the Brix range for dissolved-solids indication expressed as sucrose equivalent, according to method requirements. Dual-scale coverage reduces the need for separate instruments when both parameters occur in the same laboratory programme. Pack configuration as one piece simplifies assignment to workstations, teaching labs or shared quality-control areas that rely on handheld refractometry.
This article belongs on Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about Handheld refracto. ORA 3SA (with ATC), analog, 0-28 % NaCl, 0-32 % Brix
What is this article?
Handheld refracto. ORA 3SA (with ATC), analog, 0-28 % NaCl, 0-32 % Brix is the article on this page. Luminix Health distributes KERN for laboratory use. It sits in Refractometers & polarimeters, inside Spectroscopy & photometry, in Instruments de précision.
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.
