Penetrometer

We are offering penetrometer for penetration measurements of asphalt.
Purpose:
gd-2801e1 penetrometer for penetration measurements of asphalt is designed and made as per the national standard gbt4509 “test methods for needle penetration of petroleum asphalt”, and t0604 “asphalt needle penetration test” in the industry standard jtj052 specification and test methods of bitumen and bituminous mixture for highway engineering. It is suitable to determine needle penetration of petroleum asphalt, modified asphalt, liquid petroleum asphalt and residues after evaporation of emulsified asphalt.
technical characteristics and performance:
1. Gd-2801e1 penetrometer for penetration measurements of asphalt integrates new design concepts on penetrometer all over the world. It is advanced, beautiful, and delicate;
2. The newly designed up and down assembly have coarse adjustment and fine adjustment, so it can be adjusted freely.
3. Gd-2801e1 penetrometer for penetration measurements of asphalt adopts a newly designed heating structure. The heating and temperature measurement devices can be separated from the constant temperature bath, so it is easy to be operated.
4. Equipped with automatic temperature controller and a high precision temperature sensor, so it can conveniently set controlling temperature and it is with high temperature controlling accuracy.
