Introduction The computer intelligent asphalt penetration tester is a precision measuring instrument independently developed by our company. It is based on the national standard of the People's Republic of China GB/T4509 "Determination of Penetration of Petroleum Bitumen" and the Transportation Industry Standard of the People's Republic of China JTG E20-2011 "Technical requirements for road engineering asphalt and asphalt mixture" - T0604 "asphalt penetration test" technical requirements and related provisions of the design and manufacture, mainly for asphalt measurement, the sample placed in a constant temperature bath of 25 ° C ± 0.1 ° C, A standard needle with a load of 100 g ± 0.05 g, which moves vertically without significant friction, and the depth of penetration of the asphalt sample vertically within 5 seconds is called asphalt penetration to identify the viscosity of the asphalt. The greater the penetration of the asphalt, the smaller the viscosity of the asphalt and the softer the asphalt. Technical Parameters: Needle-in time control device: You can select 0-99 seconds respectively, and the time error is less than ±0.1 seconds. Needle penetration device: Precision displacement measuring device. Needle penetration accuracy: ±1 penetration. Maximum penetration depth: 400 penetration. Constant temperature bath: It is a hard glass cylinder. Standard needle: 2.5±0.05g, in line with GB/T4509, T0604 specifications. Lifting bracket: Freely adjustable for easy alignment of the needle tip with the sample plane
