Overview
The RONGJIDA SYD-2806G high temperature asphalt softening point tester is used to determine the temperature at which asphalt softens under specified conditions and falls to 25mm. The instrument complies with the JTJ052-2000 standard of the Ministry of Transportation.
Features
1. The temperature is automatically controlled by the instrument, with no human error.
2. External temperature probe, sensitive to temperature response.
3. The speed is controlled by PID and fuzzy logic algorithm, and the temperature increases linearly.
4. Comes with backlit blue screen display, more environmentally friendly and intuitive.
5. New Appearance, more convenient operation.
6. Magnetic stirringdevice, the test temperature is more uniform.
7. Record test results automatically and manually, and calculate the average value automatically.
Principle
The instrument controls the heating speed through PID and fuzzy logic algorithm to realize linear heating. Under the action of magnetic stirringdevice, ensure the uniform temperature of the test medium. When the asphalt sample softens under specific conditions and drives the steel ball to fall to the specified distance (25.4mm), the instrument records the temperature at this time, which is the softening point of the asphalt.
Applications
Asphalt material testing
Steps
1. Prepare the specimen and the steel ball.
2. Set the instrument parameters.
3. Start the test, and the instrument automatically controls the temperature rise.
4. Observe the sample falling, and the instrument automatically or manually records the softening point temperature.
5. After the test, the instrument automatically calculates the average value.
Notice
• Power supply voltage is 220V.
• Before use, check whether the ball mass (3.5g +/- 0.05g) and diameter (9.53mm) meet the standards.
• Pay attention to the temperature measurement range of the instrument (-5~ 270 ° C) and the test range (5~ 180 ° C).
• Ensure that the heating rate meets the requirements of (5 +/- 0.5) ° C/min.
• Please pay attention to safety during operation to avoid burns.
