Viscosity measurement services

Project Description

PTB provides viscosity measurement services to customers from GB:

supply of Newtonian reference liquids with certified values of dynamic and kinematic viscosity. (Currently about 30 reference liquids with viscosities at 20 C between 1mPas and 700 000 mPas are available)
Calibration of glass capillary viscometers (suspended-level, U-tube and Cannon-Fenske viscometers).
