C120 Falling weight deflectmeter/falling weight bearing capacity of foundation Tester/Light Drop Weight Tester

This handheld instrument is mainly used to determine the value of subgrade deflection under dynamic loads in order to assess the carrying capacity of subgrade; also, to assess the degree of subgrade compaction method by comparison.

It is suitable for measuring the deflection of soil and grass-roots groups.

7, the number of displacement sensors: 1;

8, displacement measurement system accuracy: less than 2%;

9, each point of measurement time: less than 35 seconds;

10, the pulse load shape: half sine wave;

11, the pulse load duration: 15-20ms;

12, bearing plate diameter: Φ300mm;

13, with a hand-held tablet PC or laptop wireless transmission of measurement data;

14, EVD automatically calculated values, display measurement curve;

15, automatic measurement deflection value, load value;

16, the station can be set;

17 can output data EXCEL report;

18, total weight: about 20 kg;
