Automated versions of these testers can handle multiple samples simultaneously, automatically fill the viscometer, detect the fluid menisci using optical or thermal sensors to measure flow time, clean and dry the viscometer, and calculate and report the results. The accuracy of the temperature control and the flow time measurement are critical for obtaining reliable kinematic viscosity values, as viscosity is highly dependent on temperature. Different types and sizes of calibrated capillary viscometers are used to cover a wide range of viscosity values.
Applications
Determining the kinematic viscosity of fuels, lubricants, hydraulic fluids, and other petroleum-based products.
Quality control to ensure products meet specified viscosity grades (e.g., SAE grades for engine oils, ISO VG grades for industrial oils).
Research and development of new petroleum products and formulations.
Monitoring the condition of in-service oils (e.g., detecting fuel dilution or oxidation).
Characterizing the flow behavior of petroleum fluids at specific temperatures.
Standards
ASTM D445：Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity)
ISO 3104:2023 Petroleum products — Transparent and opaque liquids — Determination of kinematic viscosity and calculation of dynamic viscosity
IP 71: Section 2 Glass capillary kinematic viscometers - Specifications and operating instructions
Features
