Gde-1b Double Units Engler Viscometer for Tar Vsicosity

Feature
1. ASTM D1665 This test method covers the determination of specific viscosity of tars and their fluid products
2. GB/T266
3. At 20 Celsius
4.2 sample
5...Can calculate the average value of results
6...Engler viscometer
Introduction
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.
