WNE-1B Engler Viscometer (Double Units) can make determination for 2 samples at the same time in the same temperature. WNE-1B Engler Viscometer (Double Units) Purpose The instrument is designed and made as per the National Standard GB/T266 "Test Methods for Engler Viscosity of Petroleum Products” and the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is used to determine the ratio obtained by dividing the time of flow, in s, of 200 ml of material using an Engler viscometer at a selected temperature by a factor representing the time of flow, in s, for an equal volume of water at 20 °C. The ratio is the Engler viscosity of the sample. The instrument can make determination for 2 samples at the same time in the same temperature environment. It can also calculate the average value of these test results. It is the best instrument for Engler viscosity of petroleum products and bituminous materials determination. Technical parameters 1.
