This instrument is in accordance with the industry standards of the People's Republic of China JTG E20-2011《 Test Regulations for Asphalt and Asphalt Mixture in Highway Engineering T 0620-2000《 Asphalt dynamic viscosity test (vacuum pressure reducing capillary method)" and the petrochemical industry standards of the People's Republic of China SH /T 0557-1998《 Designed and manufactured according to the requirements stipulated in the petroleum asphalt viscosity determination method (Vacuum Capillary Method). Suitable for measuring the dynamic viscosity of viscous petroleum asphalt, and also for measuring the viscosity at 0.0036 ～20.000Pa.s Other substances in the range.

1. Main technical characteristics
1、It has a capillary coefficient library, which can automatically save up to 10 sets of capillary coefficients, and can be called out directly when needed.
2、Adopt high-precision pressure sensor, keeping the vacuum at 300 mmHg±0.5mmHg Within the range and intuitively displayed by the display screen, it is clear and has high accuracy.
3、For less than 60 s The timing result system will automatically drop and automatically enter the next measurement for more than 60 s The system automatically calculates the viscosity value for the timing results.
4、The mean and error percentage can be automatically calculated based on user selection and settings. This calculation allows multiple times to facilitate users to get rid of unsatisfactory results, and also print out test reports.
The biggest feature of this instrument is: it adopts LCD touch screen, microcomputer control technology and high-precision pressure sensor. It has advanced technology, is easy to use, and has reliable results. It can make 4 samples at the same time.
