Gd-4508j Automatic Road Asphalt Ductility Apparatus Low Power

Feature
1. Force test is available
2. A refrigeration compressor
3. Power consumption not more than 4500 W
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
Main technical characteristics
1. There is no thread rod, guide rail, and other device in the test bath, so it is convenient to install sample. It adopts the latest design of driving part, so it is stable, synchronous, even and without any shake. The maximum elongation length is 1.0 meter.
2. It adopts microcomputer controlling technologies. The test data can be automatically printed by a micro-printer. It is equipped with RS232 port, so it can communicate with a computer.
3. It has a force measurement device, so it can determine force for one sample during ductility test.
