u-visc 220

Full range automatic viscometry systems for lubricants and other petroleum products.
The tubes are based on the well-known and proven Ubbelohde design, but only require 8-16 ml of sample and approx. 12-15 ml of solvent for cleaning. Available with single or dual solvent cleaning, the instrument measures kinematic viscosity in Newtonian fluids like lubricants, fuels or dissolved plastics between 0.15 and 25,000 mm2/s.

Designed to be versatile and flexible, yet easy use. Different models are available range from 1 bath with 1 or 2 viscometer tubes, up to 2 baths with 1 or 2 viscometer tubes per bath, where ach bath works independently.
