Original Silver schmidt Type PC N – Switzerland 341 31 000
Features :

Measurement inherently independent of impact direction, meaning no directional corrections are necessary.
High measuring accuracy due to differential optical absolute velocity encoder.
Q value (measuring the true Rebound Coeficient)
The Q value (= rebound velocity divided by inbound velocity) represents the physical rebound coeficient.
The Q value need not be corrected for impact direction.
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 (<10 N/mm2, 1’450 psi) and high strength concrete (up to 170 N/mm2, 24’650 psi).
Simple operation with “one-button”, combined with advanced tilt and twist technology use interface.
Language independent graphical menu with symbols
Automatic conversion to the required measurement unit (N/mm2, kg/cm2, psi)
