Digital concrete test hammer with microprocessor C386M


This digital concrete test hammer, microprocessor operated, entirely designed and manufactured by Matest with advanced technology, performs basic concrete testing with continuous automatic recording of all parameters in accordance with EN 12504-2 Specifications, register and process data and then transfer them to a PC The unit consists of the standard mechanical model C380, but equipped with an electronic transducer that measures the rebound values and supplies automatically the results on a graphic display.

During test performing:

  • Shows index value
  • Shows average index value
  • Allows to select measuring system in N/mm2 (MPa) or Psi
  • Shows numbers of performed rebounds
  • Shows date and time
  • Identifies tested element
  • Identifies automatically and shows rebound angle
  • Shows battery life

NOTE: The digital Matest test hammer is suitable to be connected to the Ultrasonic Tester high performance mod. C372M for combined ultrasonic and rebound tests with automatic data acquisition, processing and store of the results.
