Description
Product Introduction:
The new‑generation computer‑controlled asphalt softening point tester determines the softening point of viscous petroleum asphalt using the ring-and-ball method. This instrument is suitable for measuring the softening point of road petroleum asphalt, polymer‑modified asphalt, as well as residues from diluted asphalt and emulsified asphalt. It is the preferred choice for highway and bridge construction projects and research institutions. The device complies with the requirements specified in the People’s Republic of China standard GB/T 4507‑2014 “Method for Determining the Softening Point of Petroleum Asphalt” and in the mandatory industry standard JTG 3410‑2025 “Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering,” specifically T 0606‑2025 “Asphalt Softening Point Test” (the latest applicable standards).
Key technical features:
1.7-inch LCD touch screen display: features a clock display, current temperature readout, timer display, heating‑process visualization, test result presentation, and a function‑selection keypad—all integrated in a compact, user‑friendly interface.
2. Microcomputer‑based CPU control ensures precise heating rates, meeting the requirement of 5 ± 0.5°C/min. The instrument’s heating rate is automatically calculated by the CPU and displayed as the water temperature increase per minute, eliminating the need for manual calculations and significantly reducing the workload of laboratory personnel. Upon completion of the test, the equipment automatically displays and records the results.
3. Infrared scanning detection: When the steel ball falls, the instrument automatically detects and records the temperature at the moment the ball strikes the base plate, while simultaneously calculating the average temperature. This eliminates errors introduced by manual measurements, ensuring more accurate data and simpler operation.
4. The instrument is equipped with a German‑imported microcrystalline glass–carbon‑ceramic electric heating plate featuring magnetic stirring, and employs bottom‑heating of the glass dish for temperature control, thereby meeting the requirements of the latest industry standards. Utilizing a microcontroller‑based PID intelligent control algorithm, the instrument achieves a water‑temperature rise rate that complies with test specifications: 5.0 ± 0.5 °C/min.
5. The instrument features both high- and low-temperature test modes, which can be switched via configuration.
① When the softening point is ≤80°C, using water or purified water as the medium, the heating rate must reach and stabilize at 5 ± 0.5°C/min within three minutes.
② When the softening point is ≥80°C, using glycerin as the medium, the test temperature must reach 60°C, after which the heating rate shall be set to and maintained at 5 ± 0.5°C/min.
6. The instrument features magnetic stirring to ensure uniform water temperature within the glass dish, with adjustable stirring speed. It is equipped with a high-precision tachometer that displays the magnetic stirring speed (r/min) in real time.
7. Cooling Function: A top-mounted fan provides forced air cooling, accelerating the cooling of the heating plate and enabling quicker preparation for the next test. (Optional)
Caution! Do not turn on during the experiment!
8. Lighting Function: The lights can be turned on and off via a button, allowing clear observation of the experimental process even in low-light conditions.
9. Printing Function: The instrument is equipped with a printer that, upon completion of the test, can print the temperature and heating rate throughout the entire testing process, as well as the test results.
10. Networking Function: RS-232 communication capability, enabling real-time retrieval of device test data via this port; communication parameters are listed in the table below.
