Kinematic Viscometer  S-flow 

Automated Houillon viscometer system

s-flow

The S-flow range of instruments consist of compact, bench-top automatic viscometry systems for the analysis of Newtonian fluids. 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

The S-flow system is a self-contained viscometer systemthat consists of a thermostatic bath with circular heater anda control column. The bath contains 4 viscometer tubestogether with optical sensors to detect the flow of the samplethrough the tubes. All measuring tubes function independentlyof each other.

The control column has an LCD displaythat provides the user with information about the system’sstatus and an array of LED’s indicate the current statusof each measuring tube. Although a PC is not required tooperate the instrument, additional software is available foroperating and data storage and reporting
