2/8/2024 0 Comments Used viscosity meterInject your sample and SVM 2001 does the rest, measuring at two different temperatures successively and automatically calculating the VI. Even the viscosity index (VI) of lubricants and in-service oils can be measured from one syringe within a single measuring cycle. SVM 2001 on the other hand covers the entire viscosity, density, and temperature range with one single measuring cell, turning the search for the right capillaries into a thing of the past. Viscosity measurement made easy When testing diverse samples like used oils, finding the appropriate capillary can be a tedious task due to their limited viscosity range. For easy cleaning and maintenance, the measurement cell is accessible for cleaning without any tools thanks to its patented design. Cover the full viscosity range from 0.2 mm²/s to 30 000 mm²/s with one single measurement cell – no need to change capillaries. Simply fill the sample from a syringe and start the measurement to get the results within a few minutes. This is true for both dynamic as well as kinematic viscosities, matching the industry-relevant standards usually employed to measure the viscosities of liquids.Full description The most economic kinematic viscometer for a large variety of samples SVM 2001 allows for easy and fast viscosity measurements from 15 ☌ to 100 ☌, from fuels and lubes to used oils. Results achieved are realistic maximum ±5% accuracy when tested against values from certified viscosity reference materials. One relatively simple model discussed in this application note, for example, assumes that the temperature dependence of the viscosity of a substance follows an “Arrhenius-like” equation. Viscosities at arbitrary temperatures may be accessible via extrapolation. Since, in most cases, increasing the sample temperature decreases the viscosity, the technique presented here is suitable for substances with viscosities outside that range as well if the sample is measured at an elevated temperature. This application note describes the procedure to achieve viscosity measurements of Newtonian liquids with a digital density meter in the range of 1-3500 mPa*s (1-3500 cP). In this case, the viscosity is determined indirectly, measuring the flow resistance of the sample inside the U-tube caused by internal friction. However, a digital density meter that uses the vibrating U-tube technology for example, a METTLER TOLEDO Excellence Density Meter, can also be used to determine the viscosity of Newtonian liquid samples. The analytical instrument which is used to measure the viscosity of a fluid is known as a viscometer (also called a viscosimeter). Depending on their size and their interactions, they develop a flow resistance, giving rise to various viscosity effects. Liquids flow at different speeds-when a substance is moving, its molecules and particles slide and tumble alongside each other.
