Product introduction:
SZR - 5 type asphalt penetration tester is according to the law of the People's Republic of China national standard GB/T4509 petroleum asphalt penetration assay, transportation industry standard of the People's Republic of China JTG E20-2011 "highway engineering asphalt and asphalt mixture test regulations - T0604 technical requirements of the asphalt penetration test and the relevant provisions of the design and manufacturing, mainly is suitable for the asphalt measurements, put the sample at 25 ℃ plus or minus 0.1 ℃ constant temperature bath, load is 100 g + / - 0.05 g standard needle, with no apparent friction under vertical movement, The depth of vertical penetration of asphalt samples within 5 seconds is called the penetration of asphalt to determine the viscosity of asphalt.
The higher the penetration of asphalt, the lower the viscosity of asphalt, the softer the asphalt.
Main technical parameters:
1. Needle entry time control device: 0-99 seconds can be selected, and the time error is less than 0.1 seconds.
2. Penetration depth device: precision displacement measurement device.
3. Needle penetration accuracy: 1 needle penetration.
4. Large needle penetration depth: 400 needle penetration.
5. Constant temperature bath: hard glass tank.
6. Standard needle: 2.5 0.05g, meeting the specification requirements of GB/T4509 and T0604.
7. Lifting bracket: it can be adjusted freely for the convenience of pointing the needle to the sample plane
