  • In rock mechanics, The Type L Original Schmidt (UTR-0563 is commonly used for the classification of rock cores and brittle rock.
  • UTR-0563 Type L Hammer is a portable and relatively inexpensive instrument for measuring the surface hardness of rock.
  • The hammer can be used efficiently in both laboratory and the field setting.
  • The mechanism of operation is simple: a hammer released by a spring, indirectly impacts against the rock surface through a plunger and the rebound is read on scale of hammer then compressive strength is read directly from the curve ranging from 10 to 70 MPa (1,450 to 10,152 psi).
  • The type L hammer is used on NX or larger core specimens or block specimens having an edge length of at least 6 cm.
  • UTR-0565 Rock Cradle apparatus consists of a universal V shaped sample holder unit suitable for all standard rock core specimen sizes from EX to NX (21.46 mm to 54.74 mm dia.) and a V shaped guide attached to the core holder to keep the rebound hammer perpendicular to the surface of the test specimen.
  • The impact area of UTC-3040E Calibration Anvil used for the calibration of rock test hammers. is hardened min. 52HRC.
