LWD-4B Marshall Stability Tester

Product Information

The LWD-4B Marshall Stability Tester adopts an integrated design, with the main unit and control system integrated together. It is easy to install and connect, and has the ability to load and measure axial loads up to 50KN, as well as measure vertical deformation. It is used for measuring the stability and flow value of the specimen size in the Marshall test with a diameter of 152.4mm. At the same time, the main unit of this testing instrument only needs to be modified slightly and equipped with relevant accessories to complete various tests that require the application of vertical loads.

Product Features:

1. It can achieve automatic loading, automatic shutdown, data display, data acquisition, peak discrimination, and peak maintenance.

2. Built in origin correction algorithm that meets regulatory requirements can eliminate flow value errors and adjust the slope of the correction line.

3. Industrial grade board design, high-precision and high-speed sampling, precise capture of loading curve feature points.

4. Adopting dual self-protection functions of hardware and software to ensure the safety and reliability of the experimental process.

5. The modular design concept is applied, and each functional module is relatively independent, making it easy to repair and maintain.

6. Equipped with a manual handle for manual loading.

7. The 7-inch touch screen display uses more reliable stainless steel physical buttons for commonly used buttons, providing a better operating feel.

8. Equipped with communication interface, optional networking PC software or networking communication protocol version.
