Description
Handheld refractometer ORA 1SA (with ATC) is an analog instrument for refractive index determination focused on salinity measurement. It covers 0–100 per mill (salinity), enabling direct optical reading of salinity-related concentration on the dedicated scale. Automatic temperature compensation (ATC) is built in to support consistent interpretation of readings when ambient temperature varies during use. The device is offered as 1 pc with a weight of 0,320 kg, which is convenient for handheld operation in laboratory and technical settings. This model from manufacturer KERN is positioned among equipment for refractive index determination and physical-property testing. Analog construction means the operator observes the scale optically without depending on an electronic display or battery supply. The 0–100 per mill salinity range addresses workflows that monitor dissolved salt content via refractometry rather than titration or conductivity alone. Compact form and ATC assistance help maintain efficient sample-to-result handling at the bench or at nearby sampling points. Supplied as a single unit, the refractometer integrates easily into existing instrument sets for routine salinity checks based on refractive index.
This article belongs on Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about Handheld refracto. ORA 1SA (with ATC), analog, 0-100 per mill (Salinit.)
What is this article?
Handheld refracto. ORA 1SA (with ATC), analog, 0-100 per mill (Salinit.) 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.
Which category should I open next?
