This instrument is based on the industry standards of the People's Republic of China JTG E20-2011《 In the test procedures for asphalt and asphalt mixtures for highway engineering T0622-1993《 Asphalt Engra Viscosity Test (Engra Viscometer Method) is designed and manufactured as required by the Engra Viscometer. It is suitable for measuring the time (seconds) of the asphalt flowing from the Engra Viscometer under a certain temperature and volume condition and the distilled water at 25 seconds. ℃The ratio of time (seconds) of time outflow is the Englades viscosity of asphalt, and the unit is Englades.

1. Main technical characteristics
1、This instrument has a bench-type, integrated, double inner pot structure. The inner and outer pots are all made of stainless materials. The interior of the inner pot has been specially treated, and its finish meets the requirements of the test.
2、The outflow time is displayed, and parallel tests of two samples can be carried out at the same time, which is easy to use and high working efficiency.
3、The temperature controller adopts P、I、D Digital temperature controller with position adjustment function has convenient parameter setting and high temperature control accuracy.
