Dose rate meter GRAETZ GammaTwin S


  • Small, handy, calibratable dose rate meter for measuring gamma and X-ray radiation for the measurands Ḣ*(10) ambient dose equivalent rate and ambient dose equivalent H*(10) (to record the personal dose, a meter with the measurand Hp(10) must be used).
  • Detector: Energy-compensated Geiger-Müller counter tube
  • Large, digital measured value display on LC display (backlit)
  • Optional simultaneous or separate dose and dose rate display, additional analog display of dose rate as logarithmic bar display
  • 4 factory preset warning thresholds for dose and dose rate; customer-specific modification on request.
  • Switchable acoustic single pulse detection
  • Automatic continuous storage of the dose in a non flüchtiger memory.
  • Storage of the dose and the set parameters even when the battery is changed
  • Constant self-monitoring
  • Designed for rough use, aluminum housing, protection class IP54
  • Menu-driven operator guidance
  • Durable nylon belt pouch is included in delivery
  • Connection option for an external pulse probe:
    • 18526 D or ABG170 for contamination measurement (α, β, γ)
    • Immersion probe ZP1083 D (β, γ)
    • NaI scintillation probe 2002 for high-sensitivity measurements (β, γ)
  • With the probe connected:
    • Measured value display in Ips
    • Display of the temporal course of the pulse rates as a search function for tracing radioactive sources or contamination possible
    • Preselectable pulse rate warning threshold: double or triple zero effect

Compact electronic dose rate meter with a “twin display” that shows dose rate and dose simultaneously. The dose rate meter GRAETZ GammaTwin has a connection option for a pulse probe.

 

  • Large backlit LC display with a so-called “twin display”: Simultaneous display of dose rate and dose
  • Acoustic warning signal when warning thresholds are exceeded
  • Intuitive operation
  • Compact and robust design, dust and splash water protection (protection class IP54)
  • Integrated connection option for pulse probes
