Refractometers are analytical instruments that measure the refractive index (RI) of liquids.
API Gravity – Petroleum – Digital Density Meter Application Note
API Gravity – Density Meter Application Report Understanding API Gravity: API Gravity – Crude oil is an indispensable starting material for all types of products and various other fuels, oils, and lubricants. Characterization of these products is most complex and often impractical. Therefore, the measurements of more simple properties such as flash point, vapor pressure, […]
Density Meter Application Note, Concentrations
Density Meter Application Report Concentration Determinations using the Rudolph Research Analytical DDM 2911 Density Meter Introduction From purely an intuitive approach, it is easy to understand how a density meter can determine concentrations. If you were to measure the density of a pure water sample, you would find its density to be 0.9982 g/cm³ at […]
