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.
