The phrase "a refractometer for measuring" is correct and usable in written English.
It can be used when discussing the purpose or function of a refractometer, which is an instrument used to measure the refractive index of a substance.
Example: "In the laboratory, we utilized a refractometer for measuring the sugar concentration in various solutions."
Alternatives: "an instrument for measuring" or "a device for assessing".
A clinical veterinary refractometer is used for measuring and monitoring plasma protein and urine specific gravity.
A refractometer measures the bending of a beam of light as it passes from one material to another; such instruments are used, for instance, to determine the composition of sugar solutions or the concentration of tomato paste in ketchup.
The objective of this study was therefore to conduct a modern performance evaluation of a digital refractometer for TP measurement.
I brought home some of Mr. Hoffmann's Yirgacheffe, an Ethiopian coffee that I love for its unusual blueberry aroma, and measured my brewing against his with the help of a refractometer, a device that measures dissolved solids.
We used an Abbe Refractometer to measure the refractive index at different concentration levels.
However, after this stage a refractometer was used to measure Brix values of solutions instead of determination of reducing sugars.
Select a refractometer designed for the liquid you wish to measure.
Specific gravity of urine samples was measured with a refractometer and urine chemical examination was measured by dipstick tests (Combur10 Test, Roche Diagnostics Indianapolis, IN, USA).
Density of each fraction was measured with a refractometer (IATC-1E for 0 32% Brix, AS ONE and MASTER-2T for 28-62% Brix, ATAGO).
In the very few cases (18/840 flowers of B. acetabulosa and 7/845 of T. divaricatum) when the collected nectar volume was too small for the refractometer to measure sugar concentration, the average value of sugar concentration of the other two flowers from the same plant was used, in order to be able to calculate sugar content per flower.
