Saybolt Viscometer

The Saybolt Viscometer is used to measure the viscosity of bituminous materials and petroleum products by timing the flow of a fixed sample volume through a calibrated orifice at a controlled test temperature, expressed in Saybolt Universal Seconds (SUS) or Say bolt Furol Seconds (SFS) depending on the orifice type used.

For the empirical measurement of Saybolt Viscosity of petroleum products at specified temperatures between 70°F and 210°F. This is also used for determining the Say bolt Furol viscosity of bituminous materials at temperatures of 250, 275, 300, 350, 400 and 450°F. It comprises one each of Cylindrical Oil Cup, Universal Tip, Furol Tip, Bath fitted with immersion heater mounted on a stand, Dimmer stat for temperature control, Stirrer with shield. Apparatus is supplied complete with insulated handle and thermometer support, receiving flask, withdrawal tube, filter funnel, thermometer support for cup and circular spirit level.

Suitable for operation on 220 V, 50 Hz, Single Phase,
