4000 Saybolt Viscosity Bath for Automatic Viscosity Timing for Oil and Petroleum Testing Equipment

The Automatic Saybolt Viscometer Bath determines the time required for 60 mL of a petroleum sample to flow through a calibrated orifice under controlled temperature conditions. Saybolt Universal Seconds (SUS) are used for measuring the viscosity of lubricants, insulating oils, and lighter fuel grades, while Saybolt Furol Seconds (SFS) are used for heavier oils and bituminous materials.

The equipment features microprocessor-based temperature control, a four-tube capacity, and an automatic timing system that detects the 60 mL endpoint and displays the efflux time digitally. The insulated bath interior is constructed from heavy-gauge stainless steel. A cooling coil supports operation near ambient temperatures, while the removable chemical-resistant top plate simplifies cleaning and maintenance.

Manufactured by Atico Export for reliable viscosity measurement and quality control in petroleum testing laboratories.
