Measuring Scales for refractometers for better accuracy

Refractometers are some of the most listened word that is associated with blood sugar testing. Refractometers are available in many options and have variety of uses like measuring liquid concentrations and sugar levels. Sometimes refractometers are known as “Density meters” or sugar concentration meters depending on their application.

Hand held Refractometers have common measurement scales such as brix and refractive indexs. Refractometers that measure brix are known as Brix Refractometer. While measuring solutions having multiple ingredients the Brix value would total up to the dissolved unit concentration.

Analog Brix Refractometers

Brix refractometers are available in hand-held (analogue) or digital models. Hand held units would be read after putting a sample drop in the prism, while closing the daylight plate and after reading scale while wearing an eyepiece as the instrument would be held up in the eye. Having hand-held/analogue unit would determine the refractive index or brix using “Transparent system” which would be helpful in measurement of light as it passes through the prism and the sample. Having low concentration sample would have larger retraction angles so the boundary line would fall on the lower scale part, whereas having a high concentration sample would be useful for small refraction angle so the boundary line would also appear in the upper scale part.

About Brix Measuring Scale for refractometers

Brix (%) shows concentration percentage of soluble solid content in sample (water solution). The soluble solids content would be total of all solids that get dissolved within the water, such as salts, sugars, acids, protein, etc., also the measurement reading would be total of all these. Basically, Brix (%) would be the number of cane grams that contain cane per 100 gms of cane sugar solution. While measurement of sugar solution, Brix would match well with the total concentration and provide accurate readings. With solutions that contain various other components, when no one would want to know about the total concentration, you must have a chart for conversion.

Digital Brix refractometers

Digital Brix hand held refractometers would make use of “Reflected light systems. While you put a sample on prism and would press start button, the light that gets transmitted from inside the sample will refract and travel in a lot of directions. The reflection angle would be quite proportional in the reflective light index of sample and also the reflected light would be measured through a sensor and also get converted through the brix readout and refractive index.

Due to their versatility, Brix refractometers would be widely used for testing of sugar content in vegetables, wine, fruits and various other products for food. Other than their basic use refractometers are available with a lot of advantages as well. For example, you might have to measure the salinity of saltwater aquarium. In various cases refractometers can also use. The good thing is that you’ve got to carry bulky devices around anytime you want for drinking spring waters! These are portable, hand held-pocket sized refractometers for personal uses. This is quite clear that the device would be useful.

Day by day, the use of hand held refractometers is becoming quite common and these have found applications in medical laboratories, physics centers, and histological laboratories.
