DSHD-2801I Automatic Asphalt Penetrometer


Product Description

2801I Automatic Penetrometer

1.The instrument is designed and made as per the standards GB/T4509 "Test Method for Penetration of Bitumen", T0604 "Bitumen Penetration Test" in the standard JTJ052-2000 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering and ASTM D5.
2.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.
3.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 measurable 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 softer the asphalt is.
4.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.
