Penetrometer

Detailed Product Description

 Purpose and scope

The instrument is designed and made as per the technical requirement stipulated in the National Standard of Peoples Republic of China GB/T4509 Test Methods for Penetration of Bitumen, and T0604 Bitumen Penetration Test in the Industry Standard of Peoples Republic of China JTJ052-2000 Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering.

The instrument is suitable to determine the penetration of highway bitumen, modified asphalt, as well as liquid petroleum asphalt or residue of emulsified asphalt after evaporation. The test condition is as follows:

The penetration of bituminous materials is expressed as the distance that a 100 g±0.05 g standard needle vertically penetrates into the sample without any fraction in 5 s at a constant temperature bath of 25±0.1 . It is used for evaluating the consistency of asphalt. The larger the penetration is; the thinner and more soft the asphalt is.

The instrument can also be used for inspecting industry materials such as solid granule, powder, colloid, as well as food materials such as cream, glycine, etc. It has been widely used in the field of food industry, highway and traffic departments and other departments.
