Saybolt Viscosity Bath Systems
The SV3000 and SV4000 Saybolt Viscosity Baths are constant temperature systems designed for precise viscosity determinations using Saybolt viscometer tubes and orifices. These baths determine the time required for 60mL of sample to flow through a calibrated orifice under precisely controlled conditions. Saybolt Universal Seconds (SUS) is the standard measurement for lubricants, insulating oils and lighter fuel grades, while Saybolt Furol Seconds (SFS) is used for heavier oils and bitumens.

Bath Construction and Safety
The insulated bath interior is constructed entirely of heavy gauge stainless steel. Microprocessor PID circuitry assures precise temperature control within ASTM specified tolerances throughout the operating range. The chemical resistant top plate provides excellent insulation and is easily removed to allow for cleaning of the bath interior. Steel cabinet has leveling feet and a chemical resistant polyurethane-epoxy finish.
Automatic Timing Option
At the push of a button, the automatic timer starts the sample flow, senses the 60mL end point, and digitally records and displays the efflux time in 0.1 seconds resolution with an accuracy of 0.05%. Automatic timing improves testing accuracy and convenience, eliminating the chain and cork assembly and the need to manually time each sample. Timer installation is available in any configuration from 1 to 4 positions. Each port can accommodate one sensor for automatic timing operation on SV4000 Saybolt Viscosity Baths.
