GammaTwin S su Sonda Nal 2000                      GammaTwin S inserto nella funzione di Personal Dose allarm

Features

• small and handy dose rate meter for the measurement of gamma radiation and X-rays
• measurand: ambient dose rate equivalent Ḣ*(10) and
  ambient dose equivalent H*(10) (local dose)
• built-in detector: energy compensated GM tube
• large, digital indication of measured values on LC-display (backlit)
• selectable simultaneous or separate indication of dose and dose rate,  additionally analog indication of dose rate (logarithmic bar graph)
• display of the dose rate history as a search function for the detection of radioactive sources
• 4 preset dose and dose rate alarm thresholds
  (on demand adjustment of customised alarm thresholds) 
• additionally switchable acoustic single-pulse indication
• automatic and continuous storage of the dose into a
  non-volatile memory
• storage of the dose and of set parameters even during battery change
• permanent self test
• designed for rough use, housing made of aluminium,
  protection class IP54 (splashproof)
• menu-driven user navigation
• supplied with robust nylon bag
• optional: external probes, probe cable
• connection facility for an external probe:
  • 18526 D or ABG170 for contamination measurement (α, β, γ)
  • immersion counter tube ZP1083 D (β, γ)
  • NaI-scintillation probe 2002 for high-sensitive measurements (β, γ)
• with connected probe:
  • display of measured values in cps
  • display of the pulse rate history graph as a search function for the detection of  radioactive sources or contaminations
  • pre-selectable alarm thresholds: 2x background or 3x background

PLEASE NOTE:  Detecting the personal dose requires a measuring
                            instrument with the measurand Hp(10).
