Description
Hand refractometer HRB90 is a portable optical instrument for Brix concentration measurement. It features a Brix scale with an integrated thermometer covering 6–36 °C, a measuring range of 0–90 % Brix and a measuring accuracy of ±0,2 % Brix. Supplied as a single piece, the unit has a net weight of 0,7 kg and a gross weight of 1,5 kg. This refractometer from manufacturer Krüss originates from Germany (Hamburg) and is classified as a handheld refractometer with Brix scaling. The wide measuring span allows assessment from dilute solutions through to highly concentrated samples in one compact device, while the built-in thermometer supports temperature-aware observation during readings. Designed for rapid refractive-index-based determination of dissolved solids, it suits laboratory and quality-control settings that require straightforward handheld Brix checks. Clear accuracy limits and the combined scale-plus-thermometer layout help users obtain consistent concentration data without complex sample preparation. The HRB90 therefore offers a practical broad-range Brix solution in a portable format for routine analytical work.

Questions about Handheld refractometer HRB90
What is this article?
Handheld refractometer HRB90 is the article on this page. Luminix Health distributes Krüss 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.
