Viscometer VSN-3

Viscometer VSN-3

The rotational viscometer VSN-3 is designed to measure the rheological characteristics of visco-plastic bodies (drilling muds, paints, oil products, etc.), as well as to determine the dynamic viscosity of Newtonian fluids.

Specifications:

Measurement range of static shear stress (SNS), n/m sq (dy/cm sq.)

  • – spring 1: 0-45 ( 0-450 )
  • – spring 2: 0-90 ( 0-900 )
