Specification :

CONCRETE TEST HAMMER Type N, NR, L/LR, LB, DIGI-Schmidt 2000 (Non-Destructive Testing of Hardened Concrete - Surface Hardened) ASTM C-805

CONCRETE TEST HAMMER (CO-550), ASTM C-805
Code Series : CO-550.1S Type : N
Type N, displays rebound values on a mechanical sliding scale. The most frequently used device and method for non-destructive strength testing of concrete and structural components. Spring-driven hammer determines when forms may be removed, and assesses freezing or fire damage to structure. Measuring range 10 to 70 N/mm2 compressive strength, Impact energy 2,207 Nm. Supplied with carrying case including a grinding stone and operating instuction.
Dimension : 325 x 125 x 140 mm
Weight : 1.6 Kg

CONCRETE TEST HAMMER (CO-550), ASTM C-805
Code Series : CO-550.4S Type : DIGI-Schmidt 2000
DIGI-Schmidt 2000, New rebound measuring sensors & microprocessor for rapid & reproducible results, plus resolution unattainable with older manual models. Hammer connected to control display via cable. Digital display of strength values, mean value, and standard deviation for preset number of measurements. User select menu for hammer impact direction and desired engineering units (psi, MPa, kg/cm2, or N/mm2). Indicates specimen size & type for which data predicted. Measuring range 10 to 70 N/mm2 compressive strength.
