Standards: JTG E20 T2801, ASTM D5, AASHTO T49
Model: LY-0604
Description
The Automatic penetrometer is used to determine the penetration of bituminous materials. With required accessories, also can be used for test the penetration of paraffin, lubrication grease.
Features
a. Multifunction full-automatic needle penetration tester with the most advanced measuring technology.
b. Computerized control on test, the LVDT calibrated by computer guarantee the precision of result.
c. The computer control software can draw and print the needle penetration nomograph, through the nomograph can determine the penetration index PI value; asphalt equivalent softening point T800; asphalt equivalent brittle point, asphalt plastic temperature range ΔT.
d. Advanced lifting device design, easy for regulation.
e. Different standard needle, test-piece jar, thermometer, weights are available to meet different testing requirements.
