Model 0491 Viscometer - Data Sheet

ATAC viscometers provide a complete solu??on for automa??c analysis of petroleum process streams. The systems offer a choice of transmi??ers and capillary sizes and can analyse both Newtonian and non???Newtonian fluids. ATAC viscometers meet the requirements both in Processing Units for control of cut points or quality of blending components, and in Finished Products to meet quality specifica??ons. Model 491 wide bore Viscometer measures Dynamic Viscosity (cP) of petroleum products in correla??on with ASTM D445/2170. The wide bore capillary enables the accurate viscosity measurement of non???Newtonian samples, for example residual fuels. As well as Dynamic Viscosity, both analysers can provide the Kinema??c Viscosity (cSt) if the sample density is also being measured or is known to be stable or assumed (as in ASTM D2170).
