S-flow IV⁺ Kinematic Viscometer

Houillon viscosity reinvented with an optional autosampler
“The newest generation of S-flow systems offers the ultimate in fast, accurate viscosity testing and now also features an optional autosampler for fully unattended operation.”
Autosampler
Small sample volume
High throughput
Low solvent consumption
Highly accurate

Maximum throughput and ease of use with the exceptionally low sample and solvent consumption of our Houillon viscometer

The latest generation of the new S-flow is the Houillon viscometer which builds on the solid foundation of its predecessors, like the U-Visc, to offer the ultimate in automatic viscosity testing of Newtonian samples, such as petroleum products. The S-flow IV+ 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 this Houillon viscometer now also includes an optional autosampler to allow for fully unattended operation. All of this is controlled from a central user interface that takes care of result storage, autosampler control, VI calculations, and much more. This Houillon viscometer complies fully with ASTM D7279. It is the ideal system for used oil analysis labs that need to test a wide range of lubricant viscosities. Tell us more about the required specifications to receive a tailor-made viscometer system.

The specifications of our Houillon viscometer

The new S-flow IV+ Houillon viscometer consists of a 2-bath system with 2 tubes in each bath, providing a total of 4 tubes. The baths were designed to work independently, making it possible to use both baths at the same temperature, or at different temperatures, ranging from 20°C to 120°C. Other options include dual solvent cleaning and integrated duplo testing which obtains 2 flow time determinations with only 1 sample injection. 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 issues such as empty solvent supply tanks, full waste bottles, and other potential issues. The optional auto-sampler is fully modular and in-field upgradeable, meaning you can purchase the S-flow IV+ first and then upgrade to auto-sampling when the need arises.

Features

  • Applicable for fuels, base oils, formulated oils, and petroleum products as well as water-based fluids
  • Compliant with requirements for ASTM D7279, ASTM 2270 and correlation to ASTM D445
  • High throughput: up to 80 samples per hour under ideal operation 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 calibration of the optic amplifiers
  • Automatic flow time measurement with ultraprecise meniscus detection
  • Fully automatic cleaning and drying
