Hand-held refractometer. A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).The index of refraction is calculated from the observed refraction angle using Snell's law.For mixtures, . Abbe refractometers are the larger bench laboratory refractometers that provide highly accurate measurements of refractive index and Brix measurements of liquids and solids. . Focus in and read the scale value at the point where the light meets the dark area of the scale. Some benchtop meters will have a crosshair area for viewing the results.For more accuracy, the MISCO Palm Abbe digital refractometer can be equipped with a number of scales for reading ethylene glycol (EG) and propylene glycol (PG). You may select from scales for measuring freeze point, concentration by weight or volume, specific gravity, density, and even boiling point.Every Palm Abbe digital refractometer features a large easy-to-read 24-character by two-line backlit LCD display, which shows the unit of measure and reading value for each measurement. . Extensive Scale Library. The Palm Abbe refractometer can be factory programmed with tens of thousands of scale combinations from the most extensive .
Then, the values of the refractive index can be read on the scale. The modern versions of the Abbe refractometer have improved design features, such as thermo-stabilized prism mounts, fixed telescope mounts and a combined view of the shadow boundary and scale, allowing for an easier and faster reading. 4
how to use abbe refractometer
This direct reading relationship holds true ONLY for sucrose solutions. So, if you are measuring sucrose solutions with your Brix refractometer, you may read percent sucrose directly on the Brix scale. If you are reading non-sucrose solutions on the Brix scale then the readings must be converted into solution concentrations to be useful to the . Traditional handheld refractometers: These refractometers are compact and portable, making them ideal for fieldwork or on-the-spot measurements. They often have a built-in scale or a digital display for easy reading. Abbe refractometers: Abbe refractometers are more advanced and versatile than handheld models. They use a prism and a prism table .
Most digital laboratory refractometers, while much more accurate and versatile than their analog Abbe counterparts, are not capable of reading solid samples. In the late 1990s, Abbe refractometers with the capability to read at wavelengths other than the standard 589 nanometers became available.Abbe 5 refractometer supplied with glass calibration plate, contact liquid and instruction manual packed in a hard flight case for easy storage 44-520 Abbe 5 light source for mounting on instrument base.
