Bitumen Dynamic Viscometer

TBT-0620B-1 dynamic viscometer is made referring to ASTM D2171 Standard Test Method for Viscosity of Asphalts by Vacuum Capillary Viscometer.

It is used to determine the dynamic viscosity of sticky petroleum asphalts by vacuum capillary viscometer.

ASTM D2171

1. The whole device is integrated design, simple in structure, convenient in operation, powerful in function and friendly in man-machine interface;

2. The vacuum system of the device is controlled by the electric signal transmitted by the high-precision electronic pressure sensor.The working vacuum can be maintained within the range of 40kpa±0.066kpa, It can be displayed clearly and intuitively through the numbers with high precision;

3. The built-in liquid level protection system of the bathtub can intelligently control the water level of the bathtub, so as to prevent the accident of heating pipe dry burning;

4. According to the standard, the system will automatically discard the timing result less than 60s and automatically enter the next measurement. For the timing result more than 60s, the system will automatically calculate the viscosity value;

5. The system can generate test reports for all test results. The test reports are stored in the instrument in the form of independent documents for further transmission or printing;

6. According to the user's choice, the generated test report can automatically calculate the mean value and error percentage of the results of 2 to 4 parallel tests, and generate the parallel sample test report.
