Penetrometer

This instrument is designed and made as per T0604-2011 Penetration Test for Bituminous Materials in JTG E20-2011 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering and ASTM D5 Standard Test Method for Penetration of Bituminous Materials. It is used to determine the penetration of pavement petroleum asphalt, modified asphalt, liquid petroleum asphalt and emulsified asphalt. It is also suitable to test solid particle, powder, colloid and raw-food materials such as cheese, glycine, butter, cream and leavening.

 The instrument is suitable to determine the penetration of asphalt, paraffin and grease.
