About This Product
The sample is filled into the cup up to the level shown by the gauge, and the surrounding bath is heated to hold the test temperature while the flow time for 50 ml is measured. It suits petroleum products that flow as Newtonian liquids at the set temperature, but not cut-back bitumen or road oils. Two adaptations of the Redwood viscometer are available.
