  •  jumper allows board to be run with a 9V battery or AA batteries + 4 jumpers for other functions
  • high voltage power supply – adjustable from 200 to >940 volts (preset at 450V for most tubes)
  • miniature speaker instead of piezo for a classic Geiger counter sound
  • IR sensor on board
  • LED indicates activity directly from the GM tube
  • capable of displaying high CPM counts (over 1,000,000) 
  • FTDI connector outputs activity to serial port and also allows for reprogramming
    ( low cost adapter required for PC connection)

  • low battery indication
  • alarm for high counts with settable threshold triggers off of either CPM or dose
  • Setup Menu - configure parameters and features with a TV remote
