| Message: | I. Main technical characteristics:
1. DSHD-4508J Asphalt Ductility Tester adopts human oriented design theories. There is no thread rod, guide rail, and other device in the test bath, so the instrument is easy to install sample.
2.DSHD-4508J Asphalt Ductility Tester adopts the latest design of driving part, so it is stable, synchronous, even and without any shake. The ductility values can be precisely displayed. The maximum elongation length is 1.0 meter.
3. DSHD-4508J Asphalt Ductility Tester adopts microcomputer controlling technologies. The test data can be automatically printed by a micro-printer. the instrument is equipped with RS232 port and it can communicate with a computer.
4.DSHD-4508J Asphalt Ductility Tester has a force measurement device,that the instrument can determine force for one sample during ductility test.
