Digital Concrete Test Hammer

Digital Concrete Test Hammer

  PC communication, increased memory capacity and Hammerlink software
  ASTM C-805; EN-12 504-2; ENV 206; DIN 1048 part 2;
  ASTM D 5873 (rock); D 5873; JGJIT 23-2001 part 202, JJG-1993.
  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)
* PC application : Hammerlink Software
