Overview
The asphalt needle penetration matching printer is an instrument developed using a capacitance digital dial gauge combined with a numerical control circuit to measure the penetration of asphalt. The instrument meets the requirements of GB4509-84 "Petroleum Asphalt Needle Penetration Measurement Method" and T0604-2000 "Asphalt Needle Penetration Test", and is simple, convenient, and does not require preheating. It provides a high-precision * instrument for China's highway, municipal, construction, petroleum and other fields.
Product Details
Asphalt needle penetration water bathSuitable for measuring the penetration of residual substances after distillation of petroleum asphalt, liquid petroleum asphalt, or evaporation of emulsified asphalt.with100gload5Insert the asphalt sample vertically within seconds to determine its hardness.The instrument consists of a circuit system, a load linkage, a standard needle, and a time control system.
