The instrument is designed and made as per T0622 "Asphalt Engler Viscosity Test (Engler Viscometer Methods)" in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering, and the National Standard GB/T266 "Test Methods for Engler Viscosity of Petroleum Products.
It is used to determine the engler viscosity of bitumens under specified condistions.
Main technical characteristics
1. It is composed of main unit and temperature controlling device. The inner and outer containers are made of stainless steel. The inside of inner container has been specially processed, so its smooth finish meets test requirements.
2. Adopt a digital temperature controller having function of PID adjustment, so it is easy to preset parameters with high temperature controlling accuracy.
