Product Description

EVD Dynamic Deformation Modulus Tester (Hand-Held Drop Hammer Deflection Tester)

Evd dynamic deformation modulus tester, falling weight bearing capacity of foundation Tester, is for high-speed rail-based bed surface and the transition section of the Evd graded gravel testing, the new railway, the existing railway speed transformation K30 detection, as well as the highways, airports, urban transport, ports and industries. Determination of embankment under the action of moving loads bend value is to assess the amount of subgrade bearing capacity and deformation.


Features:
1. Imported sensors and some components are used for high test accuracy.
2. LCD display in English and Chinese, with corresponding Chinese and English prompts under different interfaces; with backlight, it has better visibility in various environments.
3. The operation is simple, the test speed is fast, and the detection of one point takes only 35 seconds.
4. Automatically calculate the Evd value and display the curve, which is accurate and intuitive.
5. Handheld mainframe with Bluetooth micro-printer for direct on-site printing to ensure accurate and objective test results.
6. USB transmission interface for easy connection to a computer.
7. The instrument simulates the impact of the train on the subgrade when driving at high speed. Compared with the static load test, it can better reflect the actual situation of the subgrade soil.
