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. 

Features

• Applicable for fuels, base oils, formulated oils, and petroleum products as well as water-based fluids


• Compliant with requirements for ASTM D7279, ASTM D2240, and correlation to ASTM D445


• High throughput: up to 80 samples per hour per bath under ideal operating conditions


• Very easy to use and maintain


• Small sample volume: 0.3 - 1.0 mL


• Low solvent consumption: 2 - 3 mL per sample


• Extremely accurate temperature control and flow-time measurement independent of fluid type


• Automatic flow time measurement with ultraprecise meniscus detection


• Fully automatic cleaning and drying (model dependent)


• Fast and easy tube replacement (tubes are not connected to optical sensors)


• No need to drain bath during tube replacement


• Single or dual solvent injection (model dependent)


• Integrated Cleaning Pump


• Integrated VI calculations (on 3500 model only)


• Stand-alone unit. No PC required. Software operation is available as an option


• Chemically resistant to allow for all common solvents


• Optional duplo measurement capability


• Integrated back flushing


• Optional software available

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.
