Description

The Omnitek S-flow range of instruments consists of compact, bench-top automated viscometry systems for the analysis of used and new lubricants. It is also the ideal system for used oil analysis laboratories that need to test a wide range of lubricant viscosities. Additionally, S-flow systems are used for analysis of fuels like diesel, bunker fuel and bio-fuel (feedstock), hydraulic and metal working fluids and even gelatins and inks.

Test Method

The kinematic viscosity characterizes flow behavior. This method covers the measurement of kinematic viscosity of transparent and opaque liquids; such as base oils, formulated oils, diesel oil, biodiesel blends, residual fuel oils, marine fuels, and used lubricating oils using an automated Houillon viscometer.

Electrical Requirements
