Summary
  The instrument is designed and made as per national standard of People’s Republic of China GB/T 4509-2010 Standard Test Method for Penetration of Bitumen, GB/T269 Standard Test Method for Cone Penetration of Lubricating Grease and Petrolatum and T0604-2011 Asphalt Penetration Test in the Industrial Standard of People’s Republic of China JTG E20-2011 Specifications and Test.Methods of Bitumen and Bituminous Mixture for Highway Engineering as well as ASTM D5 Standard Test Method for Penetration of Bituminous Materials and ASTM D217 Standard Test Methods for Cone Penetration of Lubricating Grease. It is mainly used to determine the needle penetration of bituminous mixture and cone penetration of lubricating grease (or petrolatum).It is also suitable to determine solid particle,powder, colloid an draw-food materials such as cheese,glycine,butter,cream and leavening.It can be widely used in food industry,highway engineering and other industrial fields.
