  • high measuring accuracy
  • reliable and safe measurement of radiation in front of the user's body (detection of a solid angle of 180°)
  • especially shaped display ensures optimum reading of measured values
  • switchable, acoustic single-pulse indication
  • 4 dose alarm thresholds
  • 4 dose rate alarm thresholds
  • menu-driven operator guidance
  • optical interface
  • storage of dose value and set parameters also during battery change
  • high reliability by continuous self control and test function
  • small and handy metallized housing made of high impact-proof plastic, easy to decontaminate
  • watertight up a a submersion depth of 0,5 m acc. to protection class IP67
