I Brief Introduction
GDE-1A ASTM D 1665 Engler Specific Viscosity Tester for Petroleum Products is made as per the national standard of People's Republic of China GB/T 266 "Test Method for Engler Viscosity of Petroleum Products, and the company standard of Shanghai Municipality Q/YXYY11 "GDE-1A Engler Viscometer. It is suitable to determine ratio between the time used by a liquid flowing out of Engler viscometer under a certain temperature and volume, and that of distilled water flowing out of Engler viscometer at 20 °C. The ratio is the Engler viscosity of liquids.
