WebRefractometers input the conversion tables into the memory of their instruments and thus by measuring their refractive index can display concentration directly. In the market place, up to 80 different instruments are available with dedicated, fit for purpose concentration scales dedicated to specific end user needs and niches. ... WebRefractometers are handheld, lightweight, portable instruments used to determine the concentration of water soluble fluids such as machine tool coolants, heat treating fluids, hydraulic fluids, plating baths, detergents, antifreeze, battery acid, etc.

Refractometers are often used in pharmaceutical applications for quality control of raw intermediate and final products. The manufacturers of pharmaceuticals have to follow several international regulations like FDA 21 CFR Part 11, GMP, Gamp 5, USP<1058>, which require a lot of documentation work. Zobraziť viac A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).

Web18. okt 2010 · Technically, refractometers measure the refractive index of a substance. Explanation: Light travels at different speeds through different materials. The refractive index is just a comparison between two numbers: the speed of light through a vacuum and the speed of light through the material you are testing—in this case honey. Websolution’s Brix factor by its refractometer reading. This is because the Brix factor for many emulsions is 1.0…so what you read on the refractometer is the actual coolant concentration in the sump. However, as the table above demonstrates, when using microemulsions, semisynthetics, and synthetics (which have Brix factors WebA refractometer is an instrument designed to measure an optical constant, which is a characteristic of the material being examined. This optical constant is known as "Refractive Index" and can be used to give valuable information about the material being tested. The fundamental definition of refractive index is based on the speed of light. preschool carrollton tx
