Description
Handheld refractometer ORA 5PB (without ATC) is an analogue instrument for refractive index determination where manual temperature handling is acceptable. Without automatic temperature compensation, readings are taken under controlled or noted temperature conditions according to laboratory practice. The compact handheld format supports bench-side checks and portable sampling in environments focused on physical-property measurement. Delivered as a single piece from manufacturer KERN, the instrument weighs 0,350 kg and belongs to equipment sets used for refractive index determination. Analogue scale operation provides direct optical readout without batteries or external power, keeping daily use simple for trained staff. It is appropriate for routine liquid screening, comparative concentration checks, and teaching or method-development contexts that do not require built-in ATC. Pair the ORA 5PB with calibrated temperature monitoring when sample temperature must be recorded alongside the refractive reading. The robust handheld design integrates easily into standard laboratory workflows for determination of physical properties.
This article is part of Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about Handh. refractometer, ORA 5PB (w/o ATC), Analogue, 1 unit(s)
What is this article?
Handh. refractometer, ORA 5PB (w/o ATC), Analogue, 1 unit(s) 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?
