scope of application:

This instrument is designed to measure the penetration of road petroleum asphalt and modified asphalt, as well as the residual penetration of liquid petroleum asphalt after distillation or emulsified asphalt evaporation. It complies with the requirements of JTG E20-2011 'T0604-2011 Asphalt Penetration Test' and GB/T 4509-2010 'Method for Determining Asphalt Penetration'.

Performance features:

1、The application of image recognition algorithm to realize automatic and accurate needle alignment reduces the operation difficulty, improves the accuracy, efficiency and fairness of the test;

2、Using computer control technology, the test process of needle, needle release, needle lifting and sample rotation is automatically completed, and the test results are automatically displayed;

3、Stepper motor subdivision control lifting structure, lifting is stable, positioning is accurate, can be automatic/manual, can coarse adjustment and fine adjustment;

4、Integrated needle rod lifting device, the needle rod is automatically lifted at the end of each test, without manual needle picking;

5、Integrated sample rotation device, the sample is automatically rotated at the end of each test, without manual rotation;

6、Built-in laser displacement sensor, original imported well-known brand, non-contact accurate measurement of displacement change;

7、Built-in semiconductor temperature control device, temperature control accuracy can reach ±0.01℃, automatic switching heating/cooling mode, no noise, no pollution;

8、Strictly implement the standard requirements, if the temperature exceeds the standard during automatic test, the temperature will be adjusted automatically and the test will continue after reaching the standard;

9、The manual needle operation is retained, and the traditional manual needle mode can be carried out at any time for comparative test;

10、The independently developed penetration online software can realize the communication between the instrument and the computer, automatically upload the experimental data, export the test record to Exce1 report file, and design the report format according to customer needs;

11、The self-developed penetration index calculation software can automatically calculate the penetration index, equivalent softening point, equivalent brittle point and plastic temperature range.
