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 suitable to determine the penetration of pavement petroleum asphalt, modified asphalt,Liquid petroleum asphalt and emulsified asphalt. It is also suitable to determine solid particle, powder,colloid and raw-food materials such as cheese, glycine, butter, cream and leavening. It can be widely used in food industry,highway engineering and other industrial departments.
I. Main technical features
It adopts digital display to show the penetration. Easy to observe.
The timing control has two grades being selected at will. The timing control accuracy is high.
3. The lifting crane can be adjusted roughly and finely. It is convenient to adjust and exact to aim.
