Penetration testing device

This device is used to determine the relative hardness of bitumen used in industry and road construction. According to the definition, bitumen penetration is the distance in tenths of millimeters that a standard needle penetrates in the bitumen in a known period of time. The degree of penetration in bitumens can determine the bitumen’s reaction to shock and the bitumen’s resistance to the load applied to it. A lower degree of penetration is a sign of harder bitumen and a higher degree of penetration is a sign of softer bitumen.
