Fully automatic asphalt softening point tester

Fully automatic asphalt softening point tester Model: SD-2801Z

SD-2801ZFully automatic asphalt softening point testerIt is designed and manufactured according to the technical requirements and relevant regulations of T0606-2011 "Asphalt Softening Point Test" in the Chinese standard GB/T 4507 "Determination of Softening Point of Petroleum Asphalt" and the Chinese industry standard JTG3410-2025 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering".
This instrument is suitable for measuring the softening point of various types of asphalt such as road petroleum asphalt, coal tar asphalt, liquid petroleum asphalt, etc. It is the preferred instrument for asphalt production enterprises, highway and bridge construction units, and relevant colleges, universities, and research institutions.
1、 Main technical features
This instrument adopts technologies such as computer intelligent control, laser automatic detection, LCD touch screen human-machine interface, screw stepper motor lifting, etc. It has the characteristics of linear heating, uniform stirring of bath solution, and automatic completion of sample detection. It is a highly automated, fast and convenient testing instrument for determining the softening point of asphalt, with accurate and reliable test results.
Instrument functional principle: SD-2801ZFully automatic asphalt softening point testerBy heating the solution medium and asphalt through a heating tube and stirring with a magnetic stirrer, the temperature inside the beaker is made uniform. The controller uses interpolation algorithm to control the output, so that the medium rises linearly at 5 ℃/min. The asphalt in the test ring begins to slowly soften during the heating process. When it reaches the softening temperature point, the asphalt in the sample ring slowly drops in a droplet shape under the gravity of the steel ball. The average temperature when the asphalt in the two sample rings drops and comes into contact with the lower baffle is the asphalt softening point temperature.
