Product Description
Model: SLH-4508F
I. Summary
TheAsphalt Ductlity Testing Machine (SLH-4508F) is designed and made according to the regulations of standards of GB/T4508, ASTMD113, T0605 bitumen ductility test, to determinate bitumen length in regulated temperature and speed stressed and be broken, and at the same time to determinate stress force for one of samples.
II. Technical characteristics
1. It integrates achievements of domestic and overseas design concepts on ductility tester. It is advanced and delicate.
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 3 pieces of sample at the same time.
5. It adopts digital temperature controller, high precision sensor and magnetic circulation pump, so the bath can be adequately circulated and the controlling temperature is precise.
6. The test sample holder can return back automatically. It will take about 10 min to return back for 2.5 meter distance.
7. Equipped with a computer communication port, it can communicate with a computer conveniently.
