Dose Rate Measuring System Graetz X5C plus

 
  • PTB-approved dose rate meter for measuring gamma radiation and X-rays
  • measuring size: ambient dose equivalent rate H*(10)
  • detector: energy compensated Geiger-Müller-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 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 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
  • compact, metallized housing made of high impact-proof plastic (easy to decontaminate), sealed for submersion up to 1 m depth (IP 67)
  • power supply by 9V battery 6LR61 or alternatively by 9V accumulator (option)
  • EMC-screened
  • RS-232 interface
  • basic unit can be combined either directly or by probe cable with various probes of the GRAETZ probe programme for
    - extending the measuring range up to 10 Sv/h
    - detecting alpha, beta and gamma radiation
    - measuring in liquids
    - measurements at "hard-to-get-to" places
    - for measuring low dose rates by means of the Scintillation Probe
  • directly to be combined with Telescope Probe DE or "CE"-Telescope for measurements from a safe distance
  • automatic probe identification
  • when using GRAETZ "CE"-probes: measuring size H*(10) (ambient dose equivalent rate)
  • when using GRAETZ "D/DE"-probes: measuring size Hx (photon dose equivalent rate)
  • extensive accessories, e.g. probes, probe cable, leather bag "D", transport case (aluminium or plastic), accumulator, recharger, PC cable, etc.

Dose Rate Meter Graetz GammaTwin

 
  • small, handy, PTB-approved and easy to operate dose rate meter for the measurement of gamma radiation and X-rays
  • measurand: ambient dose equivalent rate Measurand H Star*(10) and ambient dose equivalent H*(10) (local dose) 1)
  • detector: energy compensated Geiger-Müller-tube
  • large, digital indication of measured values on LC-display (illuminable)
  • selectable simultaneous or separate indication of dose and dose rate, additionally quasi-analog indication of dose rate (logarithmic bargraph)
  • 4 preset dose rate alarm thresholds
  • 4 preset dose alarm thresholds
  • acoustic single-pulse indication can be switched on; especially for the use in non destructive testing it is possible to reduce the pulse rate of background radiation to 1-2 counts/minute (to be set in a special menu point)
  • automatic and continuous storage of the dose
  • storage of the dose and of set parameters even during battery change
  • continuous test functions and permanent self control (displayed by a function control symbol) guarantee operational safety and suitability for daily use
  • designed for "heavy-duty" use, housing made of aluminium, protection class IP54 (splash proof)
  • menu-driven user navigation
  • power supply by 2 standard batteries type AAA 1,5V
  • supply together with a robust Nylon bag

    1) For detecting the personal dose a measuring instrument with the measurand Hp(10) is required.
