The NukAlert-ER is a unique radiation detection and measurement instrument. It is a Geiger Counter in the truest sense, but it is able to measure radiation levels far higher than traditional Geiger based devices.
  • Measures radiation rates from 1uR/hr to 700R/hr with a +/-20% accuracy
  • Will not saturate below 1000R/hr and give false readings (like traditional Geiger counters)
  • Runs on 2 AA batteries or USB power
  • Can connect to a PC via USB for data logging and reporting
  • Functions as a sensitive Geiger counter, "survey meter" and dosimeter
  • Performance verified by Oak Ridge National Laboratory
  • Size & Weight: 135mm x 70mm x 25mm, 165g
  • Range:1R/hr to 700R/hr. 20% (No saturation below 1000R/hr)
  • Accuracy (Cs137): 20%, background through 700R/hr
  • Power source: 2ea AA alkaline or NiMH cells, or USB
  • Battery Life: (2600 mAh Alkaline battery):
    • Up to 65hrs at background count rate, 24hrs above 100mR/hr
    • Up to 1 year in periodic monitor mode
    • Up to 3 years sleep mode
  • Data access by: Display, USB.
  • Display: 2 line x 16 character backlit LCD
