078-510  Ranger Survey Meter only

  • Count Range 1 to 9,999,000 counts
  • Range: 0-350,000 cpm
  • Audible beeper (can be switched off)
  • External calibration controls
  • Adjustable timer from 1 to 24 hours; default is 10 minutes
  • User selectable display for mR/hr, uSv/hr, CPM, & CPS

  •  
  • Detector: Halogen-quenched uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 area density.
  • Window: 1.77" effective diameter
  • Display: Backlit graphic LCD with backlight
  • Averaging Periods: Display will update every three seconds. At low background levels, the update is the moving average for the past 30-second time period. Time period for moving average decreases as radiation level increases.
  • Gamma Sensitivity: 3340 cpm/mR/hr (referenced to Cs-137); smallest detectable level for I-125 is .02 µCi at contact
  • Operating Range:
    - mR/hr - .001 (1µR) to 100; CPM - 0 to 350,000
    - µSv/hr - .01 to 1000; CPS - 0 to 5000
  • Energy Sensitivity: Detects Alpha down to 2 MeV. Detects Beta down to 0.16 MeV; typical detection efficiency at 1 MeV is approx. 25%. Detects Gamma down to 10 KeV through the end window.
  • Accuracy (Referenced to Cs-137): Typically ± 15% from factory.
  • Timer: One minute to 24 hours, default is 10 minutes
  • Count Light: Red LED flashes with each radiation event
  • Audio Indicator: Internally mounted beeper (can be switched off for silent operation)
  • Outputs: USB
  • Menu: Options accessed by holding down menu button. Pressing the menu button toggles you through functions. Select “+” or “–” to change setting.
