LYY-7D (1.5) Computer Low Temperature Asphalt Elongation Tester

Product Information

The 7D computer low-temperature asphalt elongation tester is the latest research intelligent elongation tester developed by our company. This instrument has been improved and upgraded on the popular old product, and has a qualitative leap in technical parameters and performance compared to the previous generation product. Its refrigeration system adopts a complete set of brand new air conditioning systems from well-known manufacturers, with reliable performance, extremely high refrigeration effect, and higher reliability.

Execution standard: T0605-2011 (JTG3410-2025) is applicable for determining asphalt ductility.

Product Features:

1. Internal and external dual circuit water circulation. During the experiment, the water circulation in the external water tank was turned off, and the internal water continued to circulate at a constant temperature, with minimal water ripples while ensuring temperature stability.

2. Driven by a high-precision stepper motor, low-speed stretching vibration is almost completely eliminated. Combined with our advanced index increasing soft start software algorithm, it can effectively reduce the impact of instrument vibration on the test results of modified asphalt.

4. Equipped with three channel force measurement (500N). It can simultaneously achieve force measurement for three channels, with curve display and peak recording functions.

5. Dual screen display system. The stretching amount, test parameters, and test time can be displayed on a digital screen closer to the user, which is more user-friendly and intuitive. The main screen is a 10.1-inch touch screen.

6. Standard micro printer, capable of printing test results.

7. It has a stretching rate of 10 and 50mm/min, which can also be freely set. Free setting of return speed, with a return speed of up to 600mm/min.

8. The displacement measurement device with a resolution of up to 0.1mm can accurately control the stretching platform to return to the initial position of the test, without the need for manual adjustment to reattach the test mold.

9. Self developed intelligent temperature control system, PID and fuzzy control algorithm, precise temperature control accuracy.

10. Concealed LED lighting fixtures.

11. Flip style transparent cover plate.

12. According to user habits, relevant physical buttons have been installed in multiple locations for easy and convenient operation. There are various input methods on the instrument, such as touch sensitive buttons, external buttons, and touch screens.

13. The small wire controlled handheld operator allows users to quickly record the elongation value and move the stretching platform using the operator.

14. The built-in memory can store 100 sets of experimental data.

15. Comes with a Windows industrial tablet and iNetYSDX testing software, with no limit on the number of records (depending on the computer's hard drive capacity), user information management, data uploading, and A4 format report printing and output.

16. Built in industrial camera that can display real-time images of the tensile specimen status.
