EVD/EVD-W

The light weight deflectometer (LWD) is a hand portable device to measure the soil in situ dynamic modulus which is used to evaluate the subsoil  degree of compaction.

It is suitable for the construction quality monitoring and testing of railway, highway, airport and indus-trial buildings under dynamic load, and especially suitable for the detec-tion of narrow sections of the site, such as transition sections of roads and bridges, backfilling of pipeline and cable, etc.

Features

1.Easy to carry and easy to operate.

2.Fast and cost-saving: only 35 seconds per measuring point.

3.CalculateEvd valueautomatically, and display the curve.

4.Wireless Bluetooth micro printer, print test results on site.

5.Testing can be achieved in difficult to reach locations.

6.It can be connected to the engineering test managementsystem, providing reliable data sources for online dataanalysis and big data management.
