Introduction
The instrument is manufactured in accordance with the requirements of the People’s Republic of China standard GB/T 266 “Method for Determination of Engler Viscosity of Petroleum Products” and Shanghai enterprise standard Q/YXYY11 “WNE-1A Engler viscometer”. It is suitable for measuring the ratio of the time (seconds) flowing out of the Engler viscometer and the time (seconds) flowing out of the distilled water at 20 ° C under the conditions of a certain temperature and volume, that is, the Engler viscosity of the liquid, the unit is the conditional degree.
Main technical features
1, the instrument is composed of tester and temperature controller, table structure, the inner and outer POTS are all made of stainless materials, the inside of the inner pot after special treatment, its finish meets the requirements of the test.
2, the temperature controller adopts digital temperature controller, easy parameter setting, high temperature control accuracy.
