Vertical Shrinkage and Expansion Tester for Concrete

Model: GL-L2

1、 Performance characteristics

1. Accurate measurement: High precision displacement sensors are used in conjunction with low expansion alloy rod calibration rod tests, with measurement errors within ± 1 μ m, ensuring the accuracy and comparability of long-term test results;

1. Accurate measurement: High precision displacement sensors are used in conjunction with low expansion alloy rod calibration rod tests, with measurement errors within ± 1 μ m, ensuring the accuracy and comparability of long-term test results;

2. 7-inch color touch screen control (industrial grade), built-in operating system, intelligent control, can intuitively display the dial gauge reading, age, shrinkage rate and shrinkage rate curve chart of the entire test process;

3. No need for long-term online observation, testing can be conducted after reaching the age limit, which improves the efficiency of equipment use;

4. Automatically calculate the shrinkage rate parameter and display it with a curve chart;

5. The experimental process does not require manual recording, all data is stored in the testing host, and the testing personnel use a USB flash drive; You can export the test results and view them through Excel software on the computer;

6. It has a test power-off recovery function. In case of unexpected shutdown during the test process, the system automatically saves the test information. After troubleshooting, the system returns to its original state, selects relevant files, and continues the test;

7. The test results come with operator identification and record the test time, specimen number, age, and specimen length;

8. Simple appearance, small size, lightweight, easy to transport and place;

9. Selection of key components such as micrometers;

10. The device can be upgraded with just one click through a USB flash drive.
