By measuring the amount of time it takes for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer, the Kinematic Viscosity Test Instrument, designed in accordance with ASTM D 445, can be used to determine the kinematic viscosity of liquid petroleum products, including transparent and opaque liquid.
Customers can choose between a manual or automatic Kinematic Viscosity Tester from Labtech.
Both dynamic (absolute) and kinematic viscosity can be used to measure and report viscosity. Despite being easily confused, the two are very different.
Kinematic viscosity is measured and reported by the majority of used oil analysis labs. Contrarily, the majority of onsite viscometers detect dynamic viscosity but are configured to estimate and report kinematic viscosity, ensuring that the reported viscosity readings correspond to the kinematic values provided by the majority of labs and lubricant oil suppliers.
It is crucial that oil analyzers comprehend the distinction between dynamic and kinematic viscosity measurements given the significance of viscosity analysis and the rising popularity of onsite oil analysis tools used to screen and augment faraway laboratory oil analysis.
The internal resistance of a fluid to flowing under the influence of gravity is known as kinematic viscosity. It is calculated by timing in seconds how long it takes for a fixed volume of fluid to travel a specific distance by gravity via a capillary inside of a calibrated viscometer at a precise temperature.
Standard units like centistokes (cst) or square millimeters per second are used to convert this value. Only when the temperature at which the test was performed is stated along with the viscosity, for instance 23 cst at 40 degrees C, is the reported viscosity valid.
Viscosity testing offers the highest level of consistency and repeatability of any test used for used oil analysis. Likewise, base oil viscosity is the single most important factor in optimal component lubrication. Viscosity, however, is more complex than first appears.
The Global Automatic Kinematic Viscosity Tester market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
This equipment is made for bath testing at constant temperature used to gauge the kinematic viscosity of petroleum products.
According to the national standard for determining kinematic viscosity and calculating dynamic viscosity, it is appropriate to estimate the kinematic viscosity of liquid petroleum products (Newtonian liquids) at a constant temperature.
There are a number of technical units that can be used to express viscosity, but the centistoke (cSt) for kinematic viscosity and the centipoise (cp) for dynamic (absolute) viscosity are by far the most used.
The ISO 3448 kinematic viscosity grading system, which is the global standard, is based on the kinematic viscosity in cSt at 40°C. The measurement of the viscosity in cst at either 40°C or 100°C can be compared to other popular kinematic viscosity systems like Say bolt Universal Seconds (SUS) and the SAE grading system.
The automatic viscosity measurements of petroleum and petrochemical products are provided by Koehler KV5000 series kinematic viscosity baths with the optical flow detection system. Up to five optical assemblies may be used, and each optical detection assembly has a communication and power connector.
For manual viscosity measurements, there are two more places available, and each one can be utilized in manual mode. To clean and make quick tube changes, the detachable Unbeholden, Cannon? Fenske, and Reverse Flow viscometer tubes are easily installed and withdrawn from the detecting assemblies.
Automates the calculation of results and viscosity measurements without the use of a separate PC. Complete circulation is provided without turbulence by motorized stirrers.
