It complies fully with in ASTM D7279 and as such, gives full correlation to ASTM D445. It is the ideal system for used oil analysis labs that need to test a wide range of lubricant viscosities.
Fast & accurate
The latest generation of S-flow builds on the strong foundation of its predecessors to offer the ultimate in automatic viscosity testing of Newtonian samples such as petroleum products. The system offers all the tried and tested advantages of a Houillon-type tube design such as short process times, small sample volume and low solvent consumption, but now also includes an optional auto-sampler to allow for fully unattended operation.
All controlled from a central software interface that takes care of result storage, auto-sampler control, calculations and much more. The new S-flow IV+ consists of 2 baths system with 2 tubes in each bath and it provides dual temperature measurements in an extremely compact package. Other options include dual solvent cleaning and integrated duplo testing which obtains 2 flow time determinations with only 1 sample injection.
Additional parameters such as tube constants and cleaning cycle are also controlled by the operator, because the sample volume is very low (0.3-1 ml), the entire measurement cycle is very short. cycle time ranges between 3-10 minutes per tube, allowing a throughput of up to 80 tests per hour. After the injection of the sample, operator presence is no longer required.
All measurement parameters, such as warmup times and cleaning parameters can be set through the high resolution 12” touchscreen or with optional PC software. The diagnostic system alerts the operator to possible issues such as empty solvent supply tanks, full waste bottles, insufficient vacuum, etc. The optional auto-sampler is fully modular and can be installed after market, meaning you can purchase the analyser first and then upgrade to auto-sampling when the need arises.
