HZ-4603C Low temperature LCD asphalt extensometer(Toothed bar)
    Low temperature LCD asphalt extensometer(Toothed bar) is used for measuring ductility of varieties of asphalt and residue of distilled asphalt and residue of distilled asphalt latex, calculating average means of ductility of three samples. The temperature is in digital display, which indicates working status and current time, velocity (adjustable), force measurement diagram and sample extension and can be connected to the printer. After it is expanded, it can be connected to the computer system. The device complies with the standard JTG E20-2011 issued by Ministry of Communication, and is widely used in manufacturing, road construction, scientific research and academies, more applicable for test for improving asphalt.
