Kinematic Viscometer EZL-KV101

Ezilab's Kinematic Viscometer EZL-KV101 serves petroleum laboratories that need capillary-based viscosity measurement rather than the rotational spindle method used by the digital and rotational viscometers elsewhere in this catalog. Spanning ambient to 100°C with 6 capillary tubes, this automatic kinematic viscometer measures how long a fixed volume of fluid takes to flow through a calibrated capillary under gravity, a method petroleum testing standards specifically call for rather than rotational viscosity alone. That capillary-based principle is the fundamental distinction here — kinematic viscosity, measured in centistokes, is the standard unit petroleum specifications and ASTM test methods reference for fuels, lubricants, and crude oil products, making this measurement approach a requirement for petroleum QC work rather than an alternative to rotational testing. The 6-tube configuration lets a lab run multiple viscosity grades or temperature points in parallel, covering the range of petroleum products with different expected viscosity levels without manually switching a single capillary between samples. Petroleum testing labs running specification compliance work that calls for kinematic viscosity in centistokes, rather than the mPa·s units the rotational and digital viscometers report, need this specific measurement method to meet those testing standards. EziLab's Automatic Viscometer and Kinematic Viscometer cover petroleum-specification viscosity testing needs across USA petroleum laboratory settings.
