Product introduction:
1:DSHD-2801E1 Penetrometer is designed and developed as perthe National Standard GB/T4509 “Test Methods for Needle Penetration ofPetroleum Asphalt”, and T0604 “Asphalt Needle Penetration Test” in the IndustryStandard JTJ052 Specification and Test Methods of Bitumen and BituminousMixture for Highway Engineering.
2:DSHD-2801E1 Penetrometer is mainly used to determine needle penetration of petroleumasphalt, modified asphalt, liquid petroleum asphalt and residues after evaporation of emulsified asphalt.
Technical characteristics and performance:
1. DSHD-2801E1 Penetrometer integrates new design concepts onpenetrometer all over the world and is advanced, beautiful, and delicate;
2. The newly designed up and down assembly have coarseadjustment and fine adjustment, so the instrument can be adjusted directly.
3.DSHD-2801E1 Penetrometer adopts a newly designed heatingstructure. The heating and temperature measurement devices can be separatedfrom the constant temperature bath, so the instrument is simply to be operated.
4. Equipped with automatic temperature controller and a highprecision temperature sensor, so the instrument can conveniently setcontrolling temperature and is with high temperature controlling accuracy.
