Please note: The X 5CEx optically corresponds to the doserate meter GRAETZ "X 5 C plus".

    • PTB-approved doserate meter for measuring gamma radiation and X-rays
    • measuring size: ambient doserate equivalent H*(10)
    • detector: energy compensated Geiger-Müller-tube
    • large digital indication of measured values on LC display (illuminable)
    • additional quasi-analog doserate indication (3,5 decades, logarithmic bar graph)
    • indication of peak and average value of doserate
    • 4 free programmable dose and doserate alarm thresholds
    • automatic or manual storage of dose and doserate values together with date and time
    • indication of residual time for staying in the current radiation field with regard to the maximum allowed dose
    • switchable acoustic single-pulse indication
    • menu driven operator guidance for easy operation, partly secured by password
    • storage of set parameters also when device is switched off or during battery replacement
    • continuous self testing and monitoring ensures high reliability
    • metallized, compact housing of high impact-proof plastic (easily to decontaminate), sealed for submersion up to 1 m depth (IP 67)
    • power supply by firmly installed accumulator
    • automatic probe identification
    • EMC-proof
    • Absolutely necessary accessories:
      - recharger "461L" for recharging the built-in accumulator
    • Optional accessories:
      - probe 

"18 550 CEx"

       for measurements at "hard-to-get-to" places 
      - probe cable "CEx", length: 1,25 m - not extendable 
    - leather bag "D" for accommodating the basic unit, the probe and the cable
