  • PTB-approved dose rate meter for measuring gamma radiation and
  • measuring size: ambient dose rate equivalent Ḣ*(10)
  • detector: energy compensated GM tube
  • large digital indication of measured values on LC display (illuminable)
  • selectable dose rate or dose indication with integration time
  • additional quasi-analog dose rate indication
    (3.5 decades, logarithmic bar graph)
  • indication of peak and average dose rate value
  • 4 free programmable dose and dose rate alarm thresholds
  • automatic or manual storage of measured dose and dose rate values
    together with date and time
  • evaluation/indication of residual time for staying in the current radiation field with regard to the maximum allowed dose
  • switchable acoustic single-pulse indication
  • clear menu-driven user navigation for easy operation,
    partly secured by password
  • storage of set parameters even when device is switched off or during battery change
  • continuous self testing and monitoring ensures high reliability
  • compact, metallized housing made of high impact-proof plastic (easy to decontaminate), sealed for submersion up to 1 m depth (IP67)
  • extensive accessories, as e.g. probes for extending the measuring range and fields of application, probe cable, leather carrying bag, transport case (aluminium or plastic), accumulator, recharger,
    PC cable, etc.
  • direct combination with Telescope Probe DE CE-Telescope or Telescope Adapter
  • automatic probe identification
  • RS-232 interface
