Introduction

The new computer asphalt needle penetration meter is a kind of advanced capacitance digital displacement sensor, combined with intelligent microcontroller circuit developed to measure the asphalt needle penetration instrument, the instrument meets GB/T4509-2010 "Petroleum asphalt needle penetration Determination Method", Astmd5-95 asphalt Needle Penetration Test and T0604-2011 Asphalt needle penetration Test. Simple to use, convenient, no temperature drift, no time drift, realize the test process automation, digitalization, computerization. It provides a kind of computerized automatic asphalt test instrument with high precision, good stability and reliable performance for highway, municipal administration, construction, petroleum and other fields in China. Mainly used for the determination of viscous road asphalt, viscous shale asphalt, and liquid petroleum asphalt, asphalt materials after distillation or emulsification test residues, petroleum wax, grease, etc. Needle penetration.
