Computer automatic intelligent asphalt softening point tester

Computer automatic intelligent asphalt softening point tester is a professional instrument for measuring the softening point of asphalt.

Computer automatic intelligent asphalt softening point tester working principle

Usually based on the ring and ball method principle, that is, the asphalt sample is injected into a sample ring of specified size, placed in a beaker filled with liquid medium (such as distilled water or glycerin), and heated at a specified heating rate to gradually soften the asphalt. When the asphalt softens to a certain extent, under the action of a steel ball of specified mass, the asphalt sample falls from the sample ring. When it falls to a specified distance, the temperature at this time is the softening point of the asphalt. The instrument controls the temperature rise through computer intelligent control, and uses electronic photoelectric detection or laser detection and other technologies to automatically detect the moment when the steel ball falls to the specified position, and record the temperature at this time, so as to obtain the softening point of the asphalt.

Main features

High degree of automation: The heating rate can be automatically controlled to maintain linear heating according to standard requirements, without manual adjustment, reducing human errors. It can automatically detect the softening point of the sample, automatically record the temperature when the softening point is reached, and some can also automatically calculate the average value and other results.
High measurement accuracy: Using high-precision temperature sensors and advanced temperature control technology, the temperature resolution can reach 0.1℃ or even higher, which can accurately measure the temperature changes during asphalt softening. The detection system has high sensitivity, such as laser detection or photoelectric detection, which can accurately capture the moment when the steel ball falls to the specified position.
Easy operation: Equipped with LCD display and touch screen, the human-computer interaction interface is friendly and the operation is simple and intuitive. The tester only needs to enter relevant parameters, such as the number of samples, test mode, etc., to start the test. Some instruments also have an animated simulation display function of the test process, which is convenient for operators to understand the progress of the test in real time.
Strong data processing function: It can automatically store a large amount of test data, which is convenient for users to query and call at any time. It has data transmission function, and can be connected to the computer through RS232, RS485 and other interfaces to upload data to the computer for further analysis and processing. It can also be connected to a micro printer to print the test results in real time.
Can test multiple samples at the same time: Some models of instruments can place multiple sample rings at the same time, and can test the softening point of multiple asphalt samples at the same time, which improves the test efficiency.
