Description
Refracto 30GS portable refractometer is supplied as a complete kit with accessories and carrying case for flexible refractive-index measurement outside a fixed laboratory bench. The portable format allows operators to bring the instrument to the sample, while the included case and accessories keep the set organised for transport and storage. As a self-contained refractometer kit, the Refracto 30GS is intended for routine analytical tasks, process checks and quality control where a handheld unit is more practical than a stationary instrument. Delivering the refractometer together with accessories and case simplifies procurement and deployment. Net weight and gross weight are each 1,5 kg for the full set. Country of origin is Japan. Available as 1.0 set from manufacturer Mettler-Toledo OnLine, this package addresses laboratories and industrial sites that need a ready-to-use Refracto 30GS portable refractometer kit rather than separate components. The configuration supports users seeking a compact, transportable refractometer solution complete with case and accessories in a single set.

Questions about Refractometer 30GS
What is this article?
Refractometer 30GS is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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?
