Viscosity of an oil is defined as its resistance to flow and Viscometer measures the flow. Monitoring viscosity is one of the most important components of any oil analysis program. Minute changes in viscosity at operating temperatures can be magnified to the extent that an oil is no longer able to provide adequate lubrication and efficiency in preventing friction between moving parts. - Allow 24 hours continuous working for 365 days. Shear rate and test temperature can be set as per requirements. Automatically advise test pressure. Make Excel test report
