Dose rate measuring system GRAETZ X5C plus

The dose rate measuring system GRAETZ X5C plus has a dose display as well as a warning function for personal radiation protection when handling ionizing radiation. The GRAETZ X5Cplus is PTB type-tested and can therefore be calibrated. The measuring system is also equipped with an RS-232 interface and an interface for connecting external probes.

Product Highlights

Dose rate measuring system GRAETZ X5C plus

Calibratable electronic dose rate measuring system in compact and robust design

Approval for use by fire departments

Extension of the measuring range by interface for external probes

Dust and splash protection as well as protection against short-term immersion in water (protection class IP67)

  • Calibratable dose rate meter for the measurement of gamma and X-ray radiation for the measurand Ḣ*(10) ambient dose equivalent rate.
  • Detector: Energy-compensated Geiger-Müller counter tube
  • Large digital measured value display on LC display (illuminable)
  • Optional dose rate or dose display with integration time
  • Additional quasi-analog display of dose rate (3.5 decades, logarithmic bar display)
  • Display of the dose rate peak value and the dose rate mean value
  • 4 freely programmable dose and dose rate warning thresholds
  • Automatic and manual storage of dose rate readings together with date and time
  • Dwell time/residual time determination
  • Switchable acoustic single pulse detection
  • Menu-driven operator guidance, partially password-protected
  • Storage of the set parameters even when the device is switched off or the battery is changed
  • High reliability due to test function and continuous self-monitoring
  • Metallized plastic housing, well decontaminable, protection class IP67
  • RS-232 interface
  • Can be combined directly or via probe cable with various probes (see brochure “Probe program”):
    • Measuring range extension up to 10 Sv/h –
    • For the detection of α-, β- and γ-radiation
    • For fluid testing
    • For measurements in hard-to-reach places
    • DE telescopic probe for measurements from a safe distance
    • Scintillation probe 2002 for measuring low dose rates
  • In custody transfer applications, the probes of the GRAETZ “CE” program are used
