Wireless Light Weight Deflectometer

Standards: ASTM E2835-11

It is used for the deflection value of layer subgrade under dynamic load, so as to evaluate the bearing capacity and deformation of subgrade. It is applicable to the monitoring and inspection of foundation construction quality of railways, highways, airports, urban transportation, ports, wharves and industrial and civil buildings under dynamic loads, especially for the inspection of narrow sections of the site, such as the inspection of transition sections and shoulders of roads and bridges (culverts), existing line foundations, etc. The instrument simulates the impact effect on the subgrade when the train is running at high speed, and can better reflect the actual stress of the subgrade soil than the static load test. It can quickly measure the dynamic deformation modulus EVD value.

Features:
* The mobile app data processing method realizes wireless data collection, wireless transmission, and is equipped with voice prompt function;
* Provide a cloud transmission port that can be connected to the project detection management system to provide a reliable data source for the realization of real-time collection of test data, online data analysis, big data management, etc;
* GPS precise positioning; Accurately display project test information
* Imported sensors and some components are adopted, with high test accuracy and more reliable test data
* Wireless Bluetooth micro printer can directly print data and photos on site to ensure accurate and objective test results;
* The operation is simple and the test speed is fast. It only takes 35 seconds to detect a little.
* Automatically calculate EVD value and display curve, which is accurate and intuitive.
* No nuclear radiation and waste gas pollution, safe and environmentally friendly operation and use.It is more convenient and fast to use.
