ASTM D 5873 (rock); D 5873; JGJIT 23-2001 part 202, JJG-1993.
Measurement inherently independent of impact direction, meaning no directional corrections are necessary.
High measuring accuracy due to differential optical absolute velocity encoder.
The Q value (= rebound velocity divided by inbound velocity) represents the physical rebound coeficient.
There is however a clear relationship beetwen the Q and the R value.
Conversion curves for a wide range of compressive concrete strengths, including low fc (
Simple operation with "one-button", combined with advanced tilt and twist technology use interface.
