Gd-4508g Low Temperature Road Bitumen/Asphalt Ductility Tester

The instrument is designed and made as per the National Standard of People's Republic of China GB/T4508. It is suitable to determine the length of the petroleum bitumen pulled on regulated condition and constant temperature as uniformed speed till broke, it is ductility shown as the unit of cm
Technical characteristics
.
2. There is no thread rod, guide rail and other device in the test trough, so it is convenient to install test sample.
3. Equipped with newly designed driving parts, it is stable and synchronous without shake during dragging procedure. The dragging speed is uniform and the ductility is accurate.
4. It can make determination for ductility of 3 pieces of samples and dragging force of 2 pieces of samples at the same time.
5. It adopts computer control techniques, so it is with high temperature controlling accuracy.
6. It has function of automatic positioning for test mold. You can make determination remotely. It is convenient.
7. It uses a large LCD to show temperature, ductility, dragging force, and other parameters clearly. The interface is friendly.
8. Equipped with a micro-printer, it can print out test data (ductility of each sample, average value of ductility, the maximum dragging force, and dragging force change curve automatically.
9. Equipped with a computer communication port, it can communicate with a computer conveniently.
